Serra Laser's Evan Shea runs us through some of the differences and similarities of a laser welder compared to TIG welding, including why a laser weld can not only be faster but also stronger and cheaper than a TIG weld.
Using the IPG LightWELD 1500 laser welder as the example, we take a look at what shielding gas is used between nitrogen gas and argon gas with a laser welder for copper, aluminium, titanium, steel, stainless steel & nickel alloys as well as discussing if back purging is still required.
Material preparation and fit up are also talked about, along with a laser welder's ability to put less heat into your material while being 4 x faster or more in some cases than TIG welding and at least 2 x faster than MIG welding while still being able to weld material as thick as 6.35mm (1/4") with good penetration.
While the price of laser welding machines is out of reach for most home welders for the moment, this is a technology that has already seen a significant reduction in price over just the last few years as well as the portability (not discussed) of laser welding units improving as well.
We're excited to see where laser welding continues to head in the future regarding motorsport fabrication across all levels, from local club racing to professional race builds.

WOW that video was the worst. You have some really loyal fans to get a 1% like rate. WHY don't you have move video of the welding? Were not buying the product we just want to see it working. I am shocked you even uploaded this. I have no clue why youtube thinks I needed to see this crap. Don't worry I will pick don't recommend this channel so I don't have to waste my time on your videos. you are welcome for the time I took me to write this comments so you don't make the same mistake twice.
We always credit Andre for his interview technique but Evan sure is a confident interviewee here too.
Evan knows his stuff! An asset to Serra and a pleasure to interview 😎 - Taz.
Yeah if only our politicians were like Evan.
Very good interview; straight to the point, no forced humor and clear and concise questions and responses. Bravo
I've had the chance of welding with Laser, and it is a total game changer. It is great for exhausts, intakes, and thin sheet, but for rollcage or other parts, I rather use MIG or TIG.
what about aluminiums?
@@adrianralte Never used it on Aluminium.
@@TonySopeano46 its perfectly fine to do it on aluminum.
How do you feel on MIG Vs TIG for cages? I'm starting to get the hang of MIG but not touched a TIG yet.
Why?
Laser welding has it's place and for bulk manufacturing of items made from thinner material it is very good. It will not currently replace mig for medium to thick materials and it is not currently cleared for use in structural components or the dairy industry. Some are as cheap as $20k for a 1000w power source but that also requires 20amp single phase power to run it.
One last thing he doesn't talk about is how dangerous they can be and how currently there is no safety legislation that covers class 4 lasers in NZ. One I have looked at that was 1500w had a safe distance for a 0.25 sec exposure to the eye of 750mtrs!! Also, they need to have dedicated welding booth like the one they had there. Please don't believe the videos from China showing women in mini skirts with no safety glasses welding with one of these, they can be very dangerous in the wrong hands.
Yes and I wouldn't recommend that this is the only video someone watches to research laser welders before buying one, nor is that the intention of this content 😎
From my personal experience using a laser welder in a previous role, they are no more dangerous than a MIG or a TIG welder noting someone negligent enough can find a way to accidentally harm or even kill themselves with a fork let alone any type of welder.
A healthy & respectful fear of what any tool or machine can do to you and your health is a great asset to have, even if they are as mundane as a builder's hammer 😎
The industries that approve (or not) laser welding is 100% a consideration. I would be surprised if any companies were blindsided here considering they will already be working to and have systems in place maintaining a set standard for their specific industry including 3rd party testing at times where relevant. It will only be a matter of time before industries currently lagging behind will get their ducks in a row for laser welding though I'm sure.
A 20amp plug is also a requirement for some other welders along with some needing 3 phase too, with a 20amp plug being the easier and more desirable option for many - Taz.
PS: While most of your questions here would be answered presale for a MIG, TIG or laser welder, I did notice Serra offer some simple free training with purchase which I'm sure would address the rest of the concerns raised here which at a glance I thought was a nice touch.
@@hpa101 Hi Taz, thanks for your reply.
Having sold welders for 25 years I can tell you that a lot of people don't care about fitting the correct plugs to machines, even some suppliers.
We have had machines turn up for repair that have either had the 15amp earth pin ground down to fit a 10amp socket or 20/32amp plugs removed and 10amp plugs fitted.
Yes, some people are that thick, I believe they are the ones who drag their knuckles in from the carpark...
I expect laser welding will become more widely used as the prices come down but NZ safety legislation needs to catch up as laser cutters are also class 4 and have been here for decades. The European saftey specs (EN 60825 etc) have been around for years and they will be the ones we adopt.
Some of the first laser welders I saw at a trade show were robotic or mechanised, not hand lasers. I've also seen laser/mig hybrid welding on thick plates, very flash.
I do hope Serra offer more than just simple training as they are capable of great welds but are limited by the knowledge of the user and the price of these machines warrants them spending the extra time.
I think guns are more dangerous than this...what are the worst than can be possibly goes wrong in using this than using a gun?
Well. Laser its always very dangerous for eyes. If you had used laser levels and reflects into surfaces the reflected glitter causes an after image.. , Remember that laser has the power in miliWatts range. And this welder have a millon times more energy . Miller company makes a iterative warning about laser burns by reflect and unintentional flash. Remember the eye damage hazard. Its worst in comparison with arc flash.
Once these become more financially viable for small shops that specialize in production of fabricated parts, this could really open up the amount of not-mild steel products on the market, given how demanding a lot of these materials are to TIG weld. The potential here is pretty exciting, especially if they ever get within spitting distance of the price of name brand consumer welders - I love welding and the skill aspect of it, but, at the end of the day, it isn't about flexing skills, it's about making parts and lowering the minimum skill level only gives more people an opportunity. We still have a ways to go though, but we're making progress.
I wouldn't be surprised if these get cheaper - I look at the cost of other laser-based machines like laser cutters, which have rapidly gotten cheaper over the past few years. These are relatively new on the market to my understanding, a new and in-development technology. In a few years these things will be at Harbor Freight.
@@quillmaurer6563 The real price drops have been in 5 to 20 watt diode lasers. I would be surprised if we get diode lasers in the hundreds of watts range any time soon, if ever.
It really becomes a process application that meets geometry and fit-up to be remotely viable. Precise machined parts is safest for utilizing laser welding processes.
I worry they're too easy to use, and people won't take the safety aspect seriously enough. I can imagine lots of reckless eye permanent eye damage.
Amazing technology though.
@@quillmaurer6563 "I look at the cost of other laser-based machines like laser cutters, which have rapidly gotten cheaper over the past few years."
- Depends on which type.
I can't wait for these things to be in my HF store.
He is hands down the best interviewer on RUclips.
He always asks the questions people really want to know, and without wasting time
The one thing no one would say from $83,837.
@@krusher74 omg! thank you for just dropping that huge piece of info. I am sure that is like question number one. More footage would be cool too but I was really glad for the rest of the info.
I love andre’s interview technique because he does the hard part of chewing the question before the viewer can digest better. However if he has free time i would be interested to know how this changes when he uses Chris Voss’ Never split the difference and The truth detector from Jack Schaffer and Marvin Karlins….tools like labeling, elicitation etc…
The questions would reach another dimension and he has some serious potential.
Very in depth line of questioning. The interviewee semed really knowledgeable and confident in his answers and seems the be comfortable enough to consider this the future of welding.
That was really great interview!!
this interview was on point by both these gentleman. answered everything
Definitely something I'd rather see than all the spot welds on production parts that like to crack
Only advantage to those is that the job is already half done for you when stripping something apart right 😂 - Taz.
Why does this interview sound like a boss and subordinate 😂 almost like the interviewer is actually a sales man and is trying to get right answers from the the interviewee
man this would be great for my line of work, welding very thin stainless conveyor belts. i wonder if this method is better for less undercut and thickness deviation than a tig torch on a linear rail
edit: turns out we do it's just above my pay grade 😂
That was a great interview! Great questions and answers
Excellent interview, direct, informative, lets the expert speak. 👍
Both of these guys know their stuff, great information thank you very much ! Love to have one of these but for a small 1 man shop I couldn’t afford it!
Excellent interview. As always, well thought out questions.
Thanks for watching and the support 😎
Excellent question structure and great responses. 👍🙂
Nice interview, clear and to the point.
Glad you enjoyed it! Cheers 😎
Wow that was amazing! The amount of information that this video just taught me was perfect. I’ve been looking into laser welders and trying to figure out if they are worth the money.
Really great interview
Yet another informative and entertaining interview by HPA.
Thanks, and keep up the great work.
I REALLY want (need) to see a cut-and-etch of an assortment of laser welds. (Differing material, thickness, joint geometry, etc.)
Laser welding has been the norm in modern cars for years now. It's AMAZING how much strength and stiffness unibodies have nowadays as a result. The strength these days doesn't even mostly come from the steel properties or material thickness anymore, it usually comes from the incredible spot welds that hold these stamped body parts together.
@@spdcrzy unibody cars are spot welded and mig
I've seen a video of a VW factory showing how the seams of automobile roofs are laser welded and that was probably 10 years ago. Here's another example: "Comau Roof Laser Welding"
Sounds pretty good to me, would love to have a go with one.
You could have a crack at this display stand yourself at SEMA which we thought was a nice touch.
Hope you get a chance to have a play in the near future. Very simple to use/hard to get wrong compared to both MIG and TIG - Taz.
Cant wait to have one of these in my garage
Wow what specific informative good questions and answers. 😊
Damn it. I'm an American consumer and I want a Laser welder now!
saw this IPG unit demo'd back at PRI '21 (sorry forget the name of the vendor) but the speed was damn impressive. this SEMA demo looked to be an even better display than what i originally saw given the more numerous and greater variety of samples shown. there were only a few coupons made from joining 1/4" plate out on the table at PRI, but still that was enough to get my attention. my Father in Law's a long retired Welder and former Vo-Tech school Welding Instructor so i literally stopped at this booth all 3 days to watch demos and gather info to bring back to show him. so between visits to the PRI Show, SEMA Show (and other industry shows) there's very few booths i've ever felt the need to stop at 3 times.🤣
The ease of use is pretty phenomenal eh! Not without pros and cons like any tool but pretty exciting tech to see trickling down slowly 😎 - Taz.
@hpa101 indeed, I was hoping you guys might cover this.👍
Sweet! This should drive TIG machine prices down
It's really the price of the argon. The tig rig will pay for itself in a couple of jobs. Unless you're using some crazy setup
also i see a "Co-Bot" in the background. at PRI '22 Lincoln had a traditional welder set up with a Co-Bot doing a "cold" demo. made me think how combing the Laser seen the previous year with a Co-Bot, one could indeed set up some small scale Automated Welding in their garage. savvy CNC guys are ALREADY using Co-Bots to load/unload parts for small production runs IN THEIR GARAGES.
Good interview, you asks some good questions about laser welding vs tig and mig. I welded 40 years, my experience is a good fit is always best and mig is best for gaps...........
Welding has been around a 100 years +. But seems like in welding machines the equipment is always expensive and big, only in the last 25/30 years has welding machines started to shrink in size and cost, even in the last 10 years welding machines has gotten smaller and lighter and more affordable for home owners....
Now if the Laser welding machines can shrink in size, cost, and be able to easily fill gaps, more and more home owners would be more likely to buy one..........
Excellent questions by the presenter!
Is it strong enough to replace rug weld for motorcycle exhaust fabrication? Will it stand the excessive heat?
Great questions
GOD if you were welding 1/4" stainless plate the thing would pay for itself in no time JUST on not having to V out or prep etc.
Very good information . I hope the prices come down for the average guy. many thanks.
torch looks big and not very handy for restricted area but for many applications it seems better for sure
Torches will get smaller, as improvements come.
Do you need to increase the preheat temp on account of lower heat inputs for materials like thicker CrMoV's...?
What's it like on thin stainless for food equipment. Will the weld cause burn through ? And do the welds clean up any discolouration with a electro acid machine ?
Love this guy
If you had access to both sides of the weld, could you weld 8-10mm aluminium plate? Thinking boat hull here...
Very cool tech!
We were very impressed with how easy these are to use too. Great to see things like this coming along to this point. They're not cheap but it really wasn't long ago the only laser welder/s I saw around that price were very large fixed location units for small electronics/jewellery applications etc! - Taz.
We usually need to disconnect all electronics from a machine in the field before welding.
Can these welders be used in the field for repairs at some point? I'm assuming we wouldn't have to worry about a ground clamp with this tech, and therefore don't need to worry about frying the electronics on a machine?
How does laser welding work on cast iron engine blocks. Do I still need to heat the block up before welding because you where saying laser welding doesn't doesn't heat the surrounding material up as much as regular welding??
I hope people are talking about the toxic dust that is created by these when welding stainless. I’m sure no one is so I will, I wish I were wrong but I’ve used these first hand and they create a heavy dust rather than a fume created by tig. Both create toxic hexavalent chromium, yes but the issue with the dust is if it gets into you’re lungs it stays there rather than being exhaled. It’s happened to me and feels like you’re lungs are burned, and I wouldn’t be surprised if I develop cancer 10 years down the road. If you look into this and ask laser regulation departments, they all seem to give the same answer “We don’t know” or seem unsure of this issue. This becomes a major issue when the area is improperly ventilated which most shops are not to the extent lasers need. Lots of these systems come out of China are not geared towards safety to begin with. I along with many others left a prestige exhaust shop for this very reason.
Fumes from TIG welding can be very toxic. Breathing them out is not really solving that issue as they enter the bloodstream too. Just want to clear that up, use extraction with adequate ventilation etc where applicable rather than hoping you can simply breathe that stuff back out dude!
Otherwise, interesting points and very valid! Sounds like where you worked had little interest in PPE for TIG or laser welding. A quick search will show you some of the safety issues with laser welding as well as the solutions. Your workplace might have made it seem 'hush hush' if they didn't want to deal with it, but that is not the same for every workplace and the information is readily available and material specific 🤘
Hope you're in a happier and healthier environment these days! - Taz.
@@hpa101 I may be wrong - but hexavalent chrome (or something as 'nasty') is a product of welding SS and most people have NO idea of the dangers from the fumes.
I have complete sympathy for you. I work in oil and gas, and know lots of welders with cancer. I know nothing about welding myself but I have hemochromatosis which causes pancreatic cancer. I was told the only cure was blood letting but i started Calcium edta and it got my heavy metals (iron), out of me according to my blood tests. Doctors didn’t tell this but they did the tests that showed the excess iron was gone and couldn’t explain it. EDTA removes any element heavier than whatever it’s bonded with (typically calcium). If you want cadmium, nickel etc out, research Ca-EDTA.
I've been watching these welders for years waiting until I can afford one. I want to try one on welding body panels together.
Really cool stuff! Wonder if it will get more affordable in the near future? Looking at other laser-based technologies, like laser cutters, I wouldn't be surprised if these are at Harbor Freight in a few years. This concept not requiring electrical conductivity of the material being welded could make for some interesting possibilities - wonder if it would be possible to weld glass, so long as the glass is opaque to the laser's light wavelength? Or plastics, though that would require a far lower-power laser.
VIP member here. I work for a Machine Tool OEM that does laser welding called TRUMPF. We have a bunch of neat laser welders. All expensive machines, but super neat.
Hey Tommy!
Do you they let you do your own after-hours work with them for the race car, or not quite that kind of workplace 😅
Still interesting tools to use either way I'm sure 😎 - Taz.
@@hpa101 If I wanted too. I'd have no problem =D since I'm an applications engineer for the company. I do all the programing and such my self. I call it practice haha but they let us use the machines after hours whenever we need for personal stuff. Just supply your own materials. Honestly for one off stuff. It would take to long. Plus I enjoy tig welding to much =D
What is the 045 welding wire he is reffering to ( min 6:20 )?
Had some bits of laser welding done. One part fractured on the first use (medium stress/high vibration part) and had to be tig welded and then machined back flat, the other looks good so far and very little distortion (very low stress part).
If laser welded rockets can make it into space, I'm sure whoever did that welding for you can figure out what they did wrong for your part 😎
Note just like TIG and MIG welding machines, not all laser welders are made equal, nor are all operators (a good one knows the strength and limits of their tool/s), and there are some circumstances where a TIG or MIG might be more suitable.
You really need to consider what is in front of you to work out the best tool for the job at the end of the day - Taz.
Welding is multi dimensional. If any one of those is not properly done you have a potential for failure. Your statement doesn’t provide enough information to make a good guess.
How can I get the Lazer welder in South Africa and at what price please
One area it needs work and may never compete is where you need full penetration welds with a smooth ID without processing and of course field work such as process/sanitary piping. LBW tends to make a mess of the ID on full penetration welds being undesirable for any type of precision piping that has a fluid flowing through it or even full penetration sheet metal welds. The weld quality is indistinguishable from gtaw I was welding bellows with a laser system and a lab analyzed the lbw and could not tell a difference. But that weld backside ……..
sounds like a settings issue.
@@Kyrazlan it is possible that it is/was, however I’ve seen it happen plenty, where you get really nasty drop through versus a nice smooth weld reinforcement like you get with tig. It could be the sweet spot was exceeded and too much energy was used causing excessive vaporization hence the nasty sharp weld reinforcement but as I’m not laser welding at my current gig to test and verify I’ll just say it’s not like TIG yet. It’s gotten way better than the older YAG systems but still not TIG.
One con of manual laser welding is the narrow fusion boundary, which is hour glass shaped. This can cause LOF that isnt visually inspectable.
Do you have a link covering this topic for people to read? I'm sure anyone seeing your comment that is interested in welding in general would be interested to read your source for sure 🤘
Cheers for sharing - Taz.
@@hpa101 Sorry I don't. This is based on experience. Laser welding is a very common process in the aerospace industry. Mostly used for critical structure applications that require minimum reinforcement, offset and HAZ.
I wish we saw this in action more
I love efficiency
Is laser welding stronger or as strong as all the other conventional welding? Can it hold structural?
If there is less internal stress, full penetration, and it is more consistent it should be far stronger for the applications it is suited to.
very nice
Wow I like this
How do you weld pipe schedule 80 or 160 thick wall close square butt with full penetration as you said don’t need any bevel preparation ? I’m talking close square butt well with thickness over 20mm .
What is the motorsport application you are using this for?
I'd put questions like this to the supplier to make sure you are getting the right tool for your application. Ask a few of them. It's also a good way to get a feel for the support of a company before you purchase anything too - Taz.
look great as long as the weld is not overhead or out of position welds
Love this new tech, how much for the units?
10 to 20k
Are there opportunities for someone who has never welded?
Great questions for what seems like a great product if it really performs as described.
Shame the fit up range isn't wider, but i reckon that can be improved, even if it means manufacturer un-supported operator trickery. I can already see some nerd and his hot-rod uncle coding a robotic arm how to gap-weld 🤣
Really seems like a better way to weld.
Pros and cons to everything but this certainly has some solid advantages over MIG and TIG - Taz.
What would happen if you got an arc flash? Would it damage your eyes more than stick , Tig or mig?
Blindness
Technically the laser is simply concentrated light. No electricity at all so no arc flash risk!
Very informative! Never saw a laser welder before.. I hope the price comes down in the future..
You and me both, they're a very accessible piece of kit skill wise 😎 Glad you enjoyed this one and cheers for the comment - Taz.
I got the impression that it had no downsides over Tig/mig besides cost because it is a newer technology. Is that fair to say? Surely there is some reason why it wont replace those processes entirely, right?
I don't think that is completely fair to say noting just like Arc, MIG and TIG welders etc, there are many different laser welders out there with strengths and weaknesses as well as a HUGE range of applications for welding from tiny medical devices and jewellery to vehicles to ships and large buildings etc in a rage of environments and locations (even under water!)
I'm not sure one tool is ever going to cover such a massively broad range of requirements personally. Might get close though! Only time will tell - Taz.
is this as strong as regular welder
I love innovation.. I'm pretty sure this would have a safety feature so you don't end up playing laser tag in the workshop.... 😅
Yes !
Ebay chinese cans and headers have been using this lately, strong
Thank you for the interview! How to protect lenses?
Laser welding needs a different type of visor to TIG welding to protect the lenses in your eyes if that's what you mean? Like TIG or MIG etc, you just need to purchase the right PPE for this specific equipment - Taz.
@@hpa101 I meant laser optical system. Is it necessary to protect it from the melted droplets? Thank you.
@@MercBenz-oc5fo different welders will have different designs, best you get in touch with whatever specific company provides the unit you're looking at noting laser welding is more comparable to TIG welding than MIG welding, with MIG welding having a lot more splatter etc than TIG or laser to the point it's not directly comparable when you're doing it all correctly - Taz.
"My answer is comprehensive and doesn't need to be repeated."
"So, what you're saying is you do complete answers and there's no need to sum them up?"
After thinking about the dangers of having a handheld laser in the shop, I can see why they are focusing on selling to only manufacturers.
Nitrogen in the atmosphere is what gives weld porosity when you run low on the actual gas you are supposed to be using star gold
What’s it run
My concern with laser welding is, to some owner/investor types it's a depreciable capital purchase that enables employers to lower their welder pay scales. To a welder or an engineer it's a really expensive machine that some clients are going to be wary of. I've heard "well we've validated with this and this and this, but at this point in the lifecycle we're not prepared to get everyone together to approve a new process, soooo..." more than once, and often about something involving lasers.
I don't quite understand your comment sorry but will give it a nudge.
You are concerned you will be paid less as a welder to use this is what I'm picking up, correct?
If so, I would agree it will cost a business less to both employ and train a laser welder vs a TIG welder for a higher upfront cost, if this is something then can consider for their application.
This is something we have seen many times over with various tools throughout history.
If a business wants to wait a few generations before investing that is up to them too. Being late/slow to adapt has been the death of some businesses just as jumping on things too early has been the death of others. That is just business. If it was easy, every business would be killing it and none would ever fail 😅 - Taz.
@@hpa101 As an engineer I get it from both sides. Owners want the next big thing so they can charge more for it. Sales people want to be known for having the high tech stuff. Customers are easily misled. And MIG/TIG are hundred year old processes with volumes and volumes of validation data behind them. Most of the time the most sensible option is to use the familiar inexpensive stuff that's all around.
With regard to welder pay, what worries me is that employers will see this as a way to justify paying the lowest wages and then I will have to deal with the problems that come with hiring the lowest-paid welders in town. I kind of imagine laser is not really going to sizzle on a resume the way TIG or SMAW do. All the promo videos show a dainty woman in office attire using it.
Obviously laser welding has perfect applications and is a fantastic tech, I just don't yet see it as *the* successor to anything we're currently using.
@@stickyfox if an employer doest want to pay you what you want for doing the job why would you work there? Negotiate you have the power they need a Welder fabricator because they can't do it themselves they need you,, don't be desperate for a job or you won't get paid what you want. You are not a slave to your employer you agree to work for the pay you get complaining about it makes you look ridiculous because your the one who agreed to the terms, non union im getting paid $8 more an hour at $34/hr production mig welding then my fellow fabricators working there how? I asked for it told them why and what their getting for it and if they don't give it to me im fully willing to walk away. Really pisses me off when someone comes in as a new hire desperate because I know they are getting low pay, are going to complain, produce bad quality and they are the reason in any kind of drop of pay across the free market of employment
@@codeack101wlck I guess you'd have to ask some of the 75% of Americans who feel "trapped" in their jobs why someone would stay with a steady almost-good-enough paycheck rather than risk unemployment to find something better. With the housing shortage and skyrocketing cost of living it's beyond most working Americans' means to just go find a better job.
And on top of that, employers are actively discouraging Americans from improving their work situation. Our biggest companies and our railroads are engaging in unionbusting and wage theft, and using health insurance as leverage to keep people from jumping ship. It's not pretty out there.
The last place I worked for went through 2-3 welders who all left after a few months, and eventually shuffled the job off on an unqualified maintenance person who was later fired. None of them were making more than $25/hour. Now they just pay insane amounts of money to an out-of-state welding contractor when they need something welded. They'd rather burn fuel and add lead time and raise prices and even cut into profits... than to give the guy holding the torch another $100/week even on days he's not holding the torch. But hey that's business right? Gotta spend money to make money?
When it gets at garage level it replaces the stuff. But right now it’s way to expensive so it doesn’t make sense.
Its used a lot in moldmaking
Is a 40 pound robin Big?
Thanks for that info! Well explained. cheers
Cheers for the support, glad you enjoyed this one 😎 - Taz.
I dnt comment on things much but great interview
Thanks man, appreciate that and glad you enjoyed it 😁 - Taz
GTAW will always be superior on chrome moly and other heat treatable alloys which are quench sensitive.
So the same tech that welded gen 2 gt40 chassis back in the day
Can this technology be adapted to the auto body industry?
I'd have a chat to your chosen seller about what you need from a unit like this and they can help you figure out if it is going to suit you or if your current setup is still a better option - TAz.
3d printing is the future of welding.
I’m curious as to the limitations of welding in position (3g or 4g….or F)? And the cost of consumables (filler materials,contact tips)? Oh, and welding dissimilar metals?
They will never replace tig welders, because of the optics the gun is heavy, it's not for intricate welding round internal corners or narrow passes, more for straight lines or on CNC welders where the focusing point could be far away from the gun and just innert gas is close to the welding point. It is fun to see how the beam is melting the metal but I use it very rarely compared to tig or mig.
It already had replaced the TIG in many applications, but you are right, it is unlikely to completely replace it everywhere for everything (at least where the tech is now) just as TIG hasn't replaced other welding options either itself across the board - Taz.
You should put more pictures in yr video of what you talking about.
I've watched video extoling the virtues of Laser welding and it seemed like an awful lot of gas was being wasted.
It looked like the benefits of a more concentrated heat transfer to the materials is kind of offset by the waste of gas in the process of starting and ending a given weld.
Maybe the folks in those videos I've watched really didn't have the experience that others do. I don't know. It just seemed like alot of gas was being released into the air before and after each weld.
Which type of weld is strongest of all weld
Depends on the welding job in front of you. There are a few different types of welding for this reason - Taz.
why was he welding with only glasses for ppe? what about the potential of laser bounce that could burn skin???
You can wear more PPE than this if you wish to when laser welding. You don't have to do what others are or are not doing, you are an individual with your own brain.
If you are using a welder like this in a professional environment, talk to your employer about PPE noting you didn't mention fume extraction which can be very important in some applications too - Taz.
@hpa101 yes, fumes are a potential hazard as well. My struggle with seeing someone do this at an expo or show is that some people will not realize the dangers if they don't see the expert wearing the proper ppe for the hazards. Even the welding helmets are made with a special shield, so it is sad to me to watch something like this.
How safe I wonder on the eyes is this machine ?
Not good. Use the applicable eye protection for laser welding 😎 - Taz.
About time someone did a video on this technology. I'm seeing cheap products from China and now it is clear that some of them are not laser systems since they would need to be more expensive.
If they're any good you won't have a problem finding many people telling you that because you are not the only guy out there looking. If there is a MASSIVE price difference and the deal looks too good to be true, it could also be just that, too good to be true.
Risk vs reward, we all make our own calls 😎 - Taz.
@@hpa101 "because you are not the only guy out there looking"
You are assuming there's no censorship. They sell fake products using Facebook ads all day long and there's no venue where potential buyers can discuss things.
Same company: there's an instagram user who posts cool laser welding videos. But, any comments that are too critical probably get deleted by him/her.
They all come from China! They just bring them to the US and put a sticker on it. I have 4 lasers from China and one from the US. All the same inside. Same Raycus lasers, Same power supplies and so on.
More amazing than laser welding is the fact they had people who new what they were talking about instead of some moron asking fluff questions.
Laser welding is better in some applications. As cf is but not for submescibles. To do maintenance on field laser is no option. Check out electron beam welding if you like to weld different materials together 😊
What typical field repairs are you doing to a TIG that you can bodge together without outside help or specific replacement parts out of interest?
Not saying that isn't a valid point, depending on what goes wrong and the comparative reliability it could be, just interested in why that is a concern for you is all 😎 - Taz.
@@hpa101 I know this is an old comment, but he may be referring to underwater welding?
Thank you so much for this. I have been doubtful purely due to the sudden advertising storm on hand held laser machines lately. None or at least very few of them answer questions we all want answers to. For me this one covered the all important penetration and I am officially sold. I want one badly.... The price though... :(
Anybody in the market for a kidney? Might be able to manage a lobe of a reasonably well maintained liver too, at a stretch.
Maybe we can do a bulk kidney offering so I can get one too? haha
Have to keep needs vs wants in mind too though right! Every tool has its pros and cons but really unless we have a specific commercial need for a specific tool, it is just a want and we can still do great things fabrication wise etc with other options. In this case, they might just take a little longer comparative to using a laser welder, but the doing part is what is important at the end of the day 😎
Well that's what I think anyway 😂 Happy welding no matter which machine you are using mate! - Taz.
No but robot welding they have been around for quite a while. But laser welding only good for production not when you have to go out somewhere and fix something. And that is just a tig with a spool gun but uses laser as the heat source. Laser probably uses more electricity as well.
trying to get a quote the site aint making it very streamlined
Not something we can help with sorry. We're just talking laser welders here, we don't sell them ourselves.
Serra do have prices listed but perhaps give them a call if you have questions beyond that. Having a chat can be a good way to get a feel for a company too - Taz,
