Use a pressure washer. 135 PSI isn't even enough pressure to know if your welds are good or not. But it is more than enough to kill you if they do fail. With water, you can easily get up to 3,000 psi and if it does fail, you just have a pinhole to fill or a spilt seam. Instead of a bomb.
I work in nuclear and aerospace and we pressure test laser welded parts from 5000-9000 psi...much cleaner and better weld than tig if you have enough watts for what you're welding.
Yeah I was thinking that. Boilers for steam engines are always tested with pressurised water, never air. The reason is that air is compressible and therefore can accumulate a lot of potential energy when pressurised - water is virtually incompressible so cannot produce a lot of potential energy. The result is a tank pressurised with water cannot explode, but if pressurised with air it can!
@@stumccabe yep, and an everyday way to observe the difference is to watch slow motion video of air balloons and water balloons popping. If they are both the same balloon filled to the same size that means they have the same pressure in them. The air ballon however is MUCH more dramatic looking because the air just keeps on pushing, but the water of the water balloon only expands a tiny bit. After that the water actually holds onto most of the balloon, keeping it from gaining any meaningful speed. 1 gallon of air at 150psi is 11 gallons of air. 1 gallon of water at 15,000 psi is 1.04 gallons.
Hydro testing is very nice! What we use is 250psi hydro or 15 psi air they leak at about the same rate at those pressures too. That's what we do to test rail cars heater coils we the people bump the air number up to 50psi though just to be safe next time it's in for checks will be 10 years from the day we touched it so gotta be sure!!!!
You're more brave than I am, if indeed you were approaching that box when it was fully pressurized. Then again, you're both better welders than I am so maybe you had a reason to be confident.
NDT non destructive testing on the laser quai MiG torch welding might be safer doing a hydro test ver a pneumatic test. Great work. Question can the laser technique use the TIG hand feeding wire rod ? Thanks for any reply.
Depends on the application, From personal use, simliar travel speeds are used. Weld size, and quality especially on thinner metals, i think the laser has it everytime.
Need to see some detailed instructional videos for experienced writers and beginners alike that have never touched a laser welder. Can we still do multiple passes for infinite depth? Can I still run a 3G on 1/4” mild steel in all positions? If I’m winding a 1 Ton truck frame back together with a diamond or building one from scratch, is laser stringer due to the heat affected zone being smaller? Etc…
So i have seen many videos where they question the strength of a laser weld. So i wonder what if you layed a 7018 stick at the joint to be welded , would it be a better weld
I'd be quite interested in seeing a proper cut and etch on various materials and thicknesses of the lazer compared to other techniques on the same joint configuration. I get Lazer isn't at the point of replacing any of the other processes, but I'm curious
The one thing I've not understood about laser welding different types of metals is, does it require different types of weld wire or do they use the same wire for all metals? I've watched several videos on laser welding and it seems that of all the different metals that those videos are showcasing, they never show themselves changing out the wire for specific metals.
I wish I could afford one to try this, but the biggest use for it in a welding shop as I see it would be to run a continuous tack of sorts, using it as a perfect jigging tool.
Hey i hydro test alot of stuff larger stuff maybe 100-200 gallons take a while to get up to 50-100 psi but once they get there they build pressure stupid fast so watch out for that otherwise its super safe for the people around it compared to air!
Honestly if your a young person getting into welding this would be a good process to focus on. Really does feels like It’s going to be the next big thing.
Aye even its a small volume, hydrotesting is the safe way. I've seen a wall taken out by compressed air. Scary stuff. You want something non compressible to limit failue energy.
Still of the most powerful and affordable units out right now. youre gonna see some china im sure. Tack on another 10k and you can have a Nicer looking machine.
@@elcheapo5302 nothing wrong with that. iPhones and most high value items are made in china. Quality comes down to checks, quality control etc, not where it’s made.
@@brendancooney9401 agreed. Once you start dealing in manufacturing you'll know that quality is largely dependent on design, specifications, quality of parts used, and quality checks... All of which is dictated by the owner of the product, not the manufacturing plant.
While I agree with you 100 percent let’s face it you’d be hard pressed to find anything that’s actually made in America anymore. Stuff that claims to be made in the USA is “assembled here” the parts and components are all made overseas mostly in China. When is the last time you saw a factory in America? I remember when you couldn’t drive 50 miles without seeing working factories with smoke coming out the stacks. You can drive halfway across the country and not see a running factory today. It’s breaks my heart what has happened to our once great country.
@@Trump985 I would honestly estimate 90% of the things I buy are American made. Yesterday I ordered an extension cord made in America by Southwire and a pair of shoes made by SAS Shoes in Texas. You might have to look a bit harder or pay a bit more, but American manufacturing is not dead yet. Other than electronics, I've had pretty good success finding just about everything I need made in USA.
I see laser welding often for making resonating cavities for microwave receivers. They have tighter tolerances than soldering or brazing. Strength and flexibility don’t matter.
For someone that “ knows all about pressure vessels”’ and doesn’t use a hydro test like would be used on 99.99% of any pressure vessel testing just shows how much you don’t know. Maybe, you should drag a couple more Everlast welders up to stick them in the background for everyone to see.
i stitched my entire e36 m3 body and solid welded the whole shell and it added a crazy amount of stiffness to my chassis. im currently using the the laser welder to do sheet metal paneling and a firewall in my mini pro mod build. its amazing and works fantastic for the thin stuff. im no welder, but i finished the tubs, and paneling on the drag chassis by myself and it came out looking nice.
I got to ask being a hobby welder....is this going to reduce the need ($$$) for experienced welders in the future? Like can anybody with minimum skills complete the task with this LASER welder.
@@LibertyDankmeme every process has its place, you’re not going to stick weld a diff housing together, and you’re not going to braze the I beams on a sky scraper either.
You all are functionally insane testing that with air, few things are as horrifying as compressed air tank failures. We’re talking old school internet facesofdeath type failures. Test em with water, please.
For the love of god, please display the proper safety requirements for laser welding. You’re doing a huge disservice to the welding community by displaying such a lack of safety precaution. First, you need to wear the laser safe hood in addition to the glasses. Second, please stop putting your hand in front of the laser when you’re tacking. That’s a great way to punch a hole right through your hand. Thirdly, this must be done in a controlled environment. You’re literally pointing that thing at a fucking window and god knows who else might walk up into the shop without any PPE. Laser welding is an excellent process but it MUST be done safely. You two are barely one step away from those terrifying Chinese laser welding videos. I expect better from this channel.
All of your points are Valid, especially the hand thing, that made myself nervous. Im curious on the actual safety requirements behind double eye protection, Ive spoken with several companys about this. The double Eye pro was Highly recommended, but not something required technically. Its a powerful laser to your point and if somehow that laser bounced and went to your eyes, neither can help you as it goes right through on a direct hit.. but i can see how it could give you a second longer and save your face. The Complex was shut down for the weekend, not a soul was around for quite aways, doors were locked and we both had our safety's on.. Cant speak on the window.. we just tried to avoid pointing that way. At the end of the say we could use some safety barriers, and for all of our other laser content we have those things. -Austin
@@Welddotcom thanks for the reply! I understand in this scenario it was done safer than what was portrayed. My concern is you might be portraying this process as something that can directly replace TIG, and while the final result is comparable, the equipment required is far from it. I’ve seen too many lasers in shops with less safety than this, so I think you should stress the safety aspect more as an educator.
I was under the impression from material i have seen that laser rated eye-pro protected from direct and reflected laser damage. What makes the welding laser different?
@@legionofanon the hood is there to protect the rest of your face from laser burns. You wear a jacket and sleeves to protect your skin, shouldn’t you also wear something to protect your face?
I can't believe how irresponsible this is to test that with air pressure. I sure hope someone who doesnt understand why this is dangerous, doesn't try this themselves. You really should delete this video, highly unsafe.
So stupid never pressure test a tank with air. good way to take the forever nap. fill with water and use a pressure washer or an actual pressure pump. and see how the weld do when they fail.
I've never seen 2 ppl try so hard to be cool. Ki da like that one at the party doing his best to b everyone's buddy but just comes off as needy. That's the vibe I get from these guys fake and creepy

Approaching that thing at 135psi air pressure is insane. Not in a good haha way either. It's nuts. Use water pressure. You know, like professionals.
we de pressurized it from the other end before approaching. Water will be the method to the madness next time.
@@Kesterlath I came here to say this when they had their face next to it at 15psi.... I haven't even watched the rest of the video yet 😱
As someone who works in pneumatics, use water. Compressed gas can be terrifying and when it goes wrong it can easily be life ending.
Fill it with water first and then use the air pressure. Air is compressible and can kill you. Liquids just split and spit out a little bit
we have come to the conclusion, this is the way.
I was concerned as well. Could have exploded at any point as they walked up to it.
You're more brave than I am, if indeed you were approaching that box when it was fully pressurized. Then again, you're both better welders than I am so maybe you had a reason to be confident.
yeah!! using water would have be vastly safer!
@@finlaybichan1275 The safety censuses is water is the way! we will try it out.
We relived the pressure after a bit from the compressor end.
I really want that 2000 watt model welder. One day!
its pretty handy! treat it like a loaded gun though!
I never thought Eminem had an interest in laser welding
Great video. Nice to see Jesse still at it.
These lasers have him busier than ever!

NDT non destructive testing on the laser quai MiG torch welding might be safer doing a hydro test ver a pneumatic test.
Great work.
Question can the laser technique use the TIG hand feeding wire rod ? Thanks for any reply.
Is it faster than MIG?
YES it is !
Not a chance. This procedure is basically for thin material. I wouldn't build a dune buggy with one for sure.
Not a chance. Look at MiG videos and compare.
Depends on the application, From personal use, simliar travel speeds are used. Weld size, and quality especially on thinner metals, i think the laser has it everytime.
Does laser welding machine requires argon or any other shielding gases
Yes, Argon or Nitrogen are the main ones they use.

Different wire, the heat source does not change the fact that the filler needs to be compatible with the host material.
I can’t wait to try this out at FabTech in Orlando this year 🤘🔥
I reckon you need one at Underground!

What Laser welder was used?
Our redsabre 1500watt model
Do you have to worry about flagging someone with the laser similar to what you have to pay attention to when holding a firearm?
I don't see why it wouldn't hold decently. I've done some oxy welding/soldering that's held well enough for small home projects.
Always good to test to see
Didnt know they had a place in kc for everlast
Honestly if your a young person getting into welding this would be a good process to focus on. Really does feels like It’s going to be the next big thing.
Try filling it with water next time to prevent possible shrapnel injury.
Aye even its a small volume, hydrotesting is the safe way.
I've seen a wall taken out by compressed air.
Scary stuff.
You want something non compressible to limit failue energy.
idea to test: safety clothes and masks with laser welder, does anything really protect on direct or reflex shot
Great info
Thanks!
Should’ve used a Hydro machine!!!
This way you could really find its limits
Use a pressure washer if you want super high pressure you can get a 2500 PSI pressure washer and turn it into a balloon
I really felt like something was trying to be sold to me throught this whole video 😂

The price needs to come down considerably. It's too expensive for the average joe. At $9,999.00 still too expensive
Never use air to pressure test containers always fill them with water.
I wonder how much more that is compared to a normal welder.
Dude looks like me with my dad as a kid. I'm excited to do some welding... My dad still welding showing me till its done to completion
