There are many arm chair welding experts debating about penetration of welds and stress tests etc. Try and remember this is a trade show and NOT a LAB and NOT a TESTING facility. There are also some people posting comments this type of welding is not good and seem skip off my opening segment about how it is already used in the automotive industry for welding synchro cones to gears. Here is a good link that explains some of the benefits--- www.acornwelding.com/blog/post/5-benefits-using-laser-welding-aerospace-industry/ . Also this link---www.thefabricator.com/thefabricator/article/laserwelding/the-evolution-of-laser-welding-technology . Try and be open minded and learn about about new technologies. It may just advance your career.
Thats amazing i started welding with a stick in the seventy's and the first time i used a mig it was like a great leap forward this is like that. thanks for the video
I just got my first stick Lincoln AC 225. How big of a generator do i get next?
Paul,
A great video on laser welding. You have shown us an interesting new (to the garage builder) concept. I appreciate the time you took to pick a subject that is not the run of the mill content, like many of the YT guys show.
Thanks again for the InSite into laser welding.
Take care,
Rick
Thanks for watching.
Oh btw Paul, thank you VERY much for that 3 part series on the T5,
Rebuilt mine this summer with all the mods and upgrades suggested, and a MUCH better understanding of the functions of stuff inside thanks to you
Thank you!
That was amazing. I feel that's the future. It's always good to know tig welding, but I feel this laser welding will eventually take over.
Wow, what a time to be alive...
We had a lot of fun with this too 😎 - Taz.
It was fun having you there! -Evan
Outstanding!
Everything has an application. I think its pretty dope! Very weird clean looking weld.
that looks pretty awesome! Thanks Paul!
GEAT VIDEO PAUL! LOOKS LIKE FUN AND YOU DID GREAT WELD FOR FIRST TIME..HAVE FUN..
I worked as a production welder for a long time and part time from my actual business.. so no. But the first time using a Laser Welder.
Absolutely amazing...🙂
Thank You, Paul Learn Tech. As Much I Can Thank You, Lightsafe & David Sesdoyro Good Video
really impressive
Good job Paul. Thanks.
Ive been watching the videos from china for about 2 years on this, super excited to see it finally showing up here!
Hey Paul, always good to see you. Great video I love this type of welding, I can't wait for it to become more affordable.
True. I'd buy one today. But for 30K makes it hard to justsify
Good Job David!
Very cool !
Awesome video Paul. I've been fascinated with laser welding a long time. Man, that quickie reference to Rocket Man took me way back.... I LOVED that show back when I was a little kid.
I think you were the only one who picked that up
@@GearBoxVideo Not true, I got the reference as well. but I was reading the comments before mentioning it.
Great work on the second side of the joint. I was amazed with the uniform speed of your pass.
I wish we had gotten a better view of the first pass when you weren't wearing your glasses.
Even so, the difference in results was very noticeable.
You were right, it was an amazing result for a first attempt.
Really interesting. I really want to try it now...
Looks very very user friendly.
Welding is like a mystical,secretive art form to me lol I’ve never tried to do it before but hopefully I get the chance someday soon
Great video also!
Nice video and product
wow, nice
Started looking at this tech because I'm not a welder, but have friends who are. They took one look and asked where to get one. First application I thought of was aluminum sailboats. The manufacturers who TIG their boats, take 15 months for welding. Laser is 4x faster adn more accurate and as shown here, stronger. When a boat hull flexes and vibrates it's stiffness and strength that prevents welds from breaking over time and stress. I know what I'd want in the middle of the Pacific with no hope of rescue.
cool.
my shop just bought an IPG laser welder I am the guy they picked to use it. I start tomorrow
Let us know what you think!
Well damn bud don't leave us hanging how was it?
It’s totally different then any other type of welding. Torch angle and travel speed are the most important. I’m still getting the hang of it. The little distortion it has in stainless steel amazes me.
My shop also just bought one and I was the one they picked to run it
@@adolfoflores-mx9ll it’s definitely not like any other welding process. You gotta watch the laser not the puddle. I’ve gotten pretty good at it.
Paul many thanks for presentation. Would be helpful to show the components for a shop to stand up allowing one to weld.
I am standing up and welding . If you have a shop you can weld on any bench. Welders are portable just like any other welder.
@@GearBoxVideo as a novice could you identify the components
A bench. Various clamps and fixtures to hold materials together. Most importantly take some lessons
That’s interesting.
welding will be a lost art before you know it
Just like everything else
There are far too many welding jobs that this won't be feasible.
Like you said.. When you release the gas trigger, it does go ahead and give you about a 3 second delay of more gas --- and you're supposed to hold it steady at the end of your weld, until the gas stops. What that does is shield your weld for a those few seconds letting that last bit of your weld cool, while still under the shielded gas. If you just quickly pull away the welder right when you're done, it can make cause trouble at the end of your weld. So again, once you get to the end-- you let go of the trigger and hold that final position for those last 3 seconds of gas while the weld cools, and you'll have a perfectly finished weld.
Would be interesting to see it used on coped 4130 tubing, for roll cage / frame applications.
I’m thinking fitment would be even more critical then usual…
Thanks for sharing!
The only issue I see is that the gun is much larger than a tig torch. So in car welding could be an issue in terms of getting around the cage. You can auto feed it like a mig or weld like a hand held tig
How is the red focus light coming out of the gun produced?
i want one
all the Jedis now have a real life LIGHT SABER (for a price anyway). saw this demo'd back at PRI 2021 just with a different vendor/reseller, definitely impressive.
Well done missing the MASK Rubbish ,Thank you for all of your works.
Wish I knew how to weld
He did mention that it was welded flat, then bent..
Take my money!!!!
This is straight out of Star Trek.
...other than the imperfect eyesight. :D
My dad taught me to arc weld back in the 50s when I was a kid. This looks so much easier.
I didn't get the part about the gas. Is it being emitted out of the tube that the laser is coming out of?
I haven't been to a SEMA show in several years. Maybe next year.
Any weld requires a sheidingg gas to prevent oxidation. Stock or arc welding has flux surrounding the electrode which shields the weld
I just got my first welder Lincoln AC 225. How big of a generator do i need to get?
No cut and etch to show penetration of the weld. ? Or does it just lay down a bead on top of the material ?
Read the oother comments about penetration and try and understand that this was done at a trade show.
@@GearBoxVideo exactly .. they should have had some cut and etch examples there .
There were plenty of welded examples at the show on display...
how hot do the base metals get ? is the heat more localized to the weld area ? Or is the thermal action from the laser as hot as using electric arc ?
Think about what you are asking. Base metals have to reach a certain temp to weld.. period. Laser is more pinpoint. Less distortion. More focused heat to achieve the same outcome at the same temperature.
@@GearBoxVideo Common sense would come to that conclusion but I have little to no experience with lasers. That being said metals like aluminum take a lot more wattage to cut using a laser because of conduction so the answer might not be so clear cut. Pun intended !
It doesnt matter with laser there is no AC or DC settings like you would with TIG setup. Obviously 1" plate will require more wattage than 1/8"
Looks like a game changer, cost may reduce over time.
something U might want to think about . they have welding camera gear, & u can also find an IR coated
plexi-glass. and make a camera rig 4 this product! good luck!
I had an early video tig welding using Google Glass glasses.
Question: Would I be able to weld cast iron, cast steel, and cast aluminum with this welder?
Its the same as a TIG method .Just a different way of applying the heat. So however you weld or braze your metals doesn't change .
@@GearBoxVideo Thank you Sir
My employer has several laser weld cells for welding Mufflers and Resonators (our customer has migrated from traditional canned muffler shells/caps to plasma/laser welded shells/caps). And we stamp some body parts that our customer laser welds. Beautiful process, but due to how fine the weld beads are, the tolerances are stupidly tight (to the point that our stamping methodology had to be rethought compared to how we used to make such stampings).
Safety is another issue. At least for our IPG and Panasonic setups, I'm told that the beam will permanently blind until it has reflected off of two surfaces. As a result, the cells are often 100% light sealed when the beam is on (we use cameras inside to monitor things). I am intrigued that hand welding is an option due to such. Taking notes.
The enclosure is by Lightsafe. The company Sera Laser sells the whole package. As a production TIG welder my eyes have been burned twice by flash from other welders so as stated by David in the video safety is extremely important due to the risk of permanent. Damage.
Would it be safe to use Laser welding,as i have a pacemaker now
Since laser is light and not an electric arc, I think your concern should be towards any form of electric arc welding.
The only risk to your heart with laser welding is the possibility of it stopping when you see how fast, easy, and beautiful the result is. 😏😁
The only thing keeping me from having one, is that Price Tag.
$35,000 is a quite $$$ for the average welder !
you can try other brand laser welding machine
~$5500 for a 2kw machine direct from China via reputable suppliers with a Reci fiber laser core. They're not quite as polished but these machines are really simple at a fundamental level. Not to mention that any stainless part from China was welded with a Chinese laser. They're not outfitting factories with American lasers.
How much for the welding set up? 20k?
I was told they start at 12k
The lightwave XC they panned to is on their site for 24K!
For production this definitely would pay for it self in no time
I agree.
well that was a good job for an old bloke 😁😁😁😁
He could have opened with the 'this is bent weld'...
What happens when u got a gap that u have to fill in by weaving
Not any different that a normal weave
@@GearBoxVideo ..it's can stand a regular stress test an things?
Off the top of my head i believe the lightweld XR ($30k+ machine) has auto weaving as a function.
U can achieve the same fusion effect with brazing…. And at about 1 million dollars cheaper… way less to maintain and can buy new tips and guns starting at 15$ …. Only problem for most is it takes time to learn and skill to apply the techniques
Fusion effect? Brazing is brazing and welding is welding ...period. its not done for a "look". Can you braze for certain applications instead of weld... Yes. But its not a cosmetic thing. Ive brazed with TIG and welded with TIG. Depends on materials and engineering requirements.
This is very cool stuff.. but I can't see it being very cheap. lol
Maybe 15 years from now, we can buy a little cheap Chinese cracker box laser welder for $200 that works as good as this one.. I know that my little 120v mig can get a lot done. cheers
To get an attractive weld on the first try with the laser , is impressive to say the least. You won't see anyone doing great welds with their first try at TIG or any other welding method..The possible permanent eye damage from incorrect use sounds very concerning though.
Imagine five blokes welding on the floor with IR beams going in all directions.. Oh crap,i just got zapped in the eyeball..
Since I was a production tig welder I can tell you that every station is shielded. The booth we were in was an example of a large station. Thus the name "Lightsafe"
Yes, to be sure the PPE and safety procedures will need to be tighter with then then traditional welding, but nothing that is excessively burdensome. And I don't think this will replace traditional welding either, this will probably replace some TIG applications, but it also opens up other use cases as well.
I guess the price is the downside...🙂
yes.. but time is money. I don't see it practical for a 100% TIG replacement. I use a foot pedal when I TIG
@Robert even a small fabrication workshop could fit one of these in the budget vs the time gains in usage and staff training, but the price is still quite the stretch for the home enthusiast - Taz.
No more grinding rusty metal to join two pieces together.. laser clean them, weld them then etch for finish. Cool.
Maybe no clean at all!
You still should clean
I'm not seeing the penetration with this. Is this "laser welding" or "laser brazing"?
Do you think you could butt braze 1/8 stainless and bend it 90deg on a brake without it cracking?
typical power density for the weld regime of stainless is from 10^6-10^7 W/cm^2, so penetration of the weld is represented by the heat affected Zone (HAZ) which is a function of laser power density - i.e., function of beam diameter, laser amplitude or pump voltage supplied to the laser pump source (flash lamp or semiconductor laser diode, but usually lamps are used for high intensity welding applications) and the beam pulse width, or duration of the pulse on the material. The weld penetration is directly related to the pulse width of the laser in laser welds. For a weld to be 5 mm deep with the right focusing optics and a power density above 1,000,000 W/cm^2 pulse width should be set to from 1-5 ms, up to maybe 10 ms for a highly reflective part geometry.
I have read a lot of these comments and I think that the welders commenting have breathed in too many welding fumes.
Doubt if it's real welder
Looks robotic!
Laser welding: it's either a critical process that requires the exceptional process control of laser welding... or a $30,000 piece of equipment you can buy so you don't have to pay a *skilled* welder $1000.
I have a feeling that for most ethical employers doing real-world work, a good old Dynasty or TIG 200 will do the job.
Machines will never replace skill. But you dont see a bunch of people welding cars bodies together on assembly lines do you? Its not about replacing talent. Take the time to read my pinned comments and links to the benefits.
@@GearBoxVideo There's nearly as many cars as people in the USA. I sincerely hope we're getting close to having enough.
And your point is?
@@GearBoxVideo I guess my point is that a $30,000 welder with automatic heat control is a boon for the employer who doesn't want to pay a trained welder's salary. But to a trained welder who's got $30,000 to spend on either one laser machine or a tig/stick welder *and* a whole truck full of tools, it's gonna be a tougher sell.
I have also never in my life heard a welder say "gosh I wish there was something stronger than TIG." I suppose it's happened.
I am pretty sure my last employer will be buying one of these and putting it in the hands of a $16/hour employee, because they've been having a hard time getting a qualified welder to stay on the job at $20.
This has nothing to do with you or your channel so I'm not sure why you're being defensive. I just see a faustian bargain in this emerging new technology and I'm not ready to call arc welding "obsolete."
If wages were not in a crisis right now and the machine was 25% the price, I'd be making my own videos about why everyone needs a laser welder.
The laser welder does not replace skill. You still have to be certified to weld in certain situations. I dont think you spent the time to read the links in my pinned comment. Nobody is going to hire a person with no welding experiance for a welding position. These are not going to replace a skilled welder. I worked as a welder and can tell you its no different then using a Tig torch. The size of the torch is cumbersome and actually is worse in tight applications. It has pros and cons. I didnt make a video on why everyone needs a laser welder, i just made a video to show what new technology is available. Im not being defensive by the way. Just read the links in the pinned comments.
I don't know many, I wanna see structural testing on these. I saw a 25k machine that even has a wire add on, and I just don't trust the penatrstion.
You can easily get 100 percent with these. FYI. Laser has been used to weld synchro cones to gears for quite awhile since heat distortion is negligable
Yeah I'm thinking the same thing, I'm not seeing the penetration here. This appears to be more like laser brazing than welding.
Dont judge on a practice pieces set up for demos. Keep in mind most people trying it at the show, and there were 100's by the end of the show. They are not pros. So, they are not going to crank up the heat and have people blow thru the plates. There were many examples of perfect 100 percent pieces there. This whole thing of people sitting at home computers judging demo weld penatration is silly. Think it thru. Laser welding is used in the automotive and aerosoace industries already. It has been for years. Point of the video is that this technology is now available for small job shops. As I also mentioned the laser welds on gear assembles are a testiment to reduced distortion and embrittlement with certain alloys.
@Billy SBC you are judging penetration based on your knowledge of electron welding. This is a different process. Look at that first piece they showed. My understanding from what they explained is that it was welded from only one side and you could clearly see it melted through to the other side. Sounds like good penetration to me. Especially when they can throw that weld in a brake and bend it like that.
@@GearBoxVideo "This whole sitting at home... behind your computer... judging... think it through... "
What? Think critically and rationally? GOD FORBID!
I've been welding since 1972, and I'm sure, right around then, TIG was being introduced at some show somewhere (I don't know this, the when and where of it all, just saying "as an example...") and stick welder guys were like "There's no way this is gonna penetrate like... (name your rod)."
Technology marches on. There will always be people, and there is more of them now "visible" to us all because we all have these phones, AKA computers, empowering them, who without even trying to think about "the thing" rationally and critically, who will criticize progress. Any progress. In our recent past it was the horse and buggies, now internal combustion.
Not to say each technology hadn't reached their peak of efficiency and performance, but it was nearing that at about the same times, but after a bunch of kicking and screaming the new technology gets adopted and the horses go to pasture, the wheel smith's learn to install piston rings, and the flying car with pulse hydrogen propulsion becomes the common thing.
Rinse and repeat about every 100 years, then 50, then 25, then 10... And so on.
This doesn't just apply to technology. It applies to everything.
Ironic that the SEMA show supports - at the same time - both holding onto a "past" that is moving on and a "future" that is about to replace it.
People, he's just showing you some new technology that's out there! Geez chill out....no ones taking your stick and buzz box ya old salty dog!🙄
Lol….this not really welding, no where near the strength
You need to read the comments. Especially my pinned comment.
Wrong video. This is video on what laser welding is at a trade show.. Think it thru. A trade show. Why would you think we were putting links to stress tests? Just showing what it is. This wasnt done in a lab or a test environment.
Read the pinned comment also...
First off, i never did a short form video for this, so you really need to stop saying I had a link to a stress test. There might be some video along side of mine that made some claims, get it? again, no short form video, no links. Do yourself a favor and check where you get your info from before making stupid comments. Because someone makes a link to my video doesn't mean I made that link. Learn how the platform works.
Rethink it. You are just one of those typical people that want find fault with something, Then proved you were wrong accusing me of something I had no part of. Look at your first post. Telling me l need to do this... Etc Usually I would take this whole thread off. But I wont because its your ignorance and tone that makes you look like a fool
What happens with rust in surface?
One doesn't weld rusty metals . Any weld wuld clean the surface prior to making a weld.
Zap zap zap zap zap zap zap...
