I have been hobby welding for 50 years gas, mig, tig, stick I now restore classic cars and build restromods in my retirement about a year ago I got a 3KW laser ($19K+)that easily does full penetration from one side of 5/16" metal and also plastic panels parts can be repaired even nylon. If the fit is good no wire is needed and its about 5x+ the speed of MIG It also does cleaning and removes discoloration and can actually offer alternative to sand blasting w/o the finish issues I can restore a carburator in minutes and removing paint is simple. I was able to exceed the quality of my conventional welds in less than a day skills I had invested decades in reaching. I am able to hold and handle welded objects almost immediatly it's actually scary how soon I can handle welded parts with my bare hands and heavy gloves are almost not needed because the heat is focused on such a small area.Without the welds shrinking I can continously weld panels without having to tack weld adnauseam and very little grinding is needed. One important safety issue is that the wand/torch should be treated more akin to a gun as the laser beam will travel for long distance and can be reflected from certain surfaces, only one person should be in welding room at a time to prevent an accident. Like everything I get first the price starts to plummet shortly thereafter. Ray Stormont

Good details .

[@deankay4434]

Is the weld a soft weld as it fuses the parent metal? Like a TIG during planishing, hammer & dolly. Makes sense but curious. Thanks kindly for your answer in experience.

[@nigelbailey1711]

Got one, need u to teach me a bit more about how to use it please reach out

[@deankay4434]

@@nigelbailey1711 The best thing to do is buy the gear, PPE, leather gloves, vest and practice on material you may most likely to use. Then practice! There are excellent welding videos on KZbin and learn from mistakes. Just remember the laser is capable of thin metals. I don’t even have a TIG but my 1984 MIG is a true 150amp that does 1/2” easy, but I can install tiny wire (0.30”) and don’t have drive rollers for (0.23”) wire used on sheet metal. If you hammer & dolly you can do sheet metal better with a TIG as the weld is softer. It flattens well and requires less filler. It depends on your future requirements! Best of luck on your projects!

A bit of information to help everyone - general rule of thumb with a laser welder is 500 watts per mm of material thickness (so 1500 watts for 3mm, 2000 watts for 4mm and 3000 watts for 6mm). When you get up into the bigger wattages you will need a welding helmet but at 3000 watts you only need about shade 5, maybe shade 6 if welding aluminum. While these produce far less radiant heat than other forms of welding they do put out more invisible IR light so you do need to keep your skin covered to avoid sunburn.

[@PaganWizard]

Good to know, TYVM for sharing!!!

[@PatrickKQ4HBD]

My 5x8' utility trailer is all 19 gauge steel angle iron, which is 1mm or 0.040". A 700W unit would be perfect for my uses.

[@orcoastgreenman]

Great info… one terminology point: IR doesn’t produce suburn though… IR just produces regular old burn burn, like sticking your hand three inches below the broil element on your electric oven for a minute or two. No doubt it FEELS like sunburn, and probably sneaks up on you the same way. Sunburn is from UV light.

[@DimaProk]

I don't know how thick the plates he used at 11 min mark but it sure looks like at least 1mm thick and he said it got full penetration with 300W unit.

[@melgross]

I’ve used less power in demonstrations that worked pretty well. And for a lot of work that this might be used for, you can get to the back and weld that too.

[@lamania32]

We are using LightWeld 1500 since it's on the market in the US. I do not have enclosed room, either using the laser glasses, today my vision is like "you are looking trough a sieve". My POE: short sleeves T's, shorts, tennis or running shoes. No jokes a side the incident ray angle and reflected ray angle is always equal. ( you have to take in consideration the surface of the material you are welding is not like a mirror so the reflected ray will be like spray of rays) If you are behind the the rays you are safe. (don't pee against the wind) But recommended to use 1070wl laser glasses at list. If the ray hit you anywhere on your body its feels like a hot needle punctured your skin. We did a banana cutting video with our laser welder which is not intended for cutting, and it did cut the banana. Ours is the very first handheld by IPG. You can weld thicker, 70-80% thicker material then the factory specs, in order to do that: slow down your travel speed, with the 1500 you can do 3/8 with enough practice. I'm constantly welding 1/4- 3/8 aluminum with my LW1500 it specked for 4mm . Your parts have to be "clean" just like any other typical welding procedure, any foreign material will cause craters and will be hard to fix it on crucial parts. As he said in the video you can manually add filler metal, We do that when a larger gap present. Also with the laser your fitment has to be spot on. If you have a large weld gap the laser beam will bounce back and fort on the edges and it wont weld as intended, the rays have to penetrate you material. Also if the laser beam "escapes" your weldment it will light up everything in its way (distance depending by the wattage) you can easily light up a wooden table, shelf, or anything like it, puncture your 18V battery sitting close by your welding zone, Its kind of fun if its Lithium ion battery. 5053 0.45 filler 60-80 on wire feeder in general is good for any type of aluminum 1/8-1/4, if you go to slow you can blow trough, on thin steel or ss you can bump it up 95-105 and use higher W settings. You will save lots of time on the post processing literally no sanding required unless its specified by the designer or you want to sand it or...... You can weld up to 12X faster in most cases. Chinese units the better ones start at 8 grand and up, IPG 20+. I think Miller came out with a system for 45+ I don't know what fck they thinking its over priced. IMO IPG does not worth the price either you can pick up a few Korean brand fro half the price and its 3KW but it requires 3phase 380 and its quite large compared to the IPG1500, Also IPG gun has lots issues but the company has awesome customer support ( 4 years 6 guns trigger switch 10+times, Loop pogo connection to nozzle 6 times ( in that case you have send gun back for repairs), and galvo problems (gun replacement) Asian units have the same gun (not the same as IPG) in most cases and its 1500 US when you buy one recommended to get a replacement gun right on the bet. If you drop it accidentally you will kill the galvo, I did drop it in the first 30 days. Cons: heavy gun compared to any other type of welding procedure, cant do hard to reach areas simple because of the laser gun geometry and the extensive wire connections, inside corner welding on table is no go. you have to elevate your parts off of the table 4-6" at list. Pros: overhead welding no cherries what so ever some light sparks that's all. as I said up to 12x faster and almost 0 post processing. Oh an other tip you can do unlimited thickness V grove it and run multiple passes. its not qualified by D 1.1 but it works for other purposes.( I did fix a Bobcat arm 1/2 plate with this method and it still works did not break so far) good video thanks.

Laser welding has also been a gamechanger in mold repair. What used to involve cost-intensive grinding, filling, re-milling/re-facing, etc... can now be a two step process with far less base material removed, less material added, and less refinishing required. As a matter of fact, the welds can be so small/smooth, some molds don't even require milling. Many metals don't even require feed material. For hairline cracks in mold that doesn't require a perfect finish, you can flash weld the base material, and be done in one step with no added material/finishing.

Laser welding companies are literally all over the place in the US.

[@quinoje]

Really important: anyone in the room should have eye protection on when the machine is on. Reflected laser light can still blind you. This is different from the light generated by any other type of welder. I’m not an expert but know a physicist who specializes in laser safety in labs and she said even pets in the home of a laser cutter or welder should not be in the same room. Those open-bed types of laser cutters are really dangerous to your eyes.

The difference between laser & standard welding, Laser will permanently blind an onlooker. Tig, Arc & MiG it may hurt but it will heal. I have a friend who just recently bought one (7-10k comes to mind). He offered to loan it to our Makerspace, however without locking a room to do the work in, it’s too dangerous to others. In a factory environment, it’s different because you have controls in place.

[@TheJohn8765]

I don't think brazing is actually welding, tho. You're not melting the two surfaces and joining them via the heat and added material. Brazing just joins two+ surfaces together by adding in a melted material that acts more like glue rather than actually joining the surfaces.

[@Diving_Into_History]

I was in China last week and got to use a new laser welder model and was easily welding 5/8 mild, stainless and aluminium with full penetration. Many people compare the W's with laser welders, but there is a big difference between companies in what percentage of that wattage is converted to actual light(heat) output from the laser source. The good ones are approaching 60%. The other thing is the annual rate of dropoff of this conversion - it can be as high as 5% or more.

The Tesla Cybertruck has the highest precision welds I've ever seen. Since the Cybertruck's armor shell is bare, uncoated metal, Tesla needed to be able to weld to the inside of the body panels without overheating and discoloring the outside of the panels. So, they used computer-controlled laser welders to (for example) weld the inner stainless steel door panels to the outer cold-rolled hard fricking steel. They are such precision welds, so perfect, so controlled, they look like alien technology. Tesla left the surface discoloration for all to see. You can easily see the welds by looking inside the doors (which are 100% unpainted stainless steel). BTW, most of what you read about the Cybertruck is false, based on my 4 months of ownership. It drives like a spaceship of a sportscar with a rigid chassis on the road, it's surprisingly smooth, quiet and comfortable, even when railing a twisty road. Off-road, nothing can touch it. It just walks away from Land Rovers, Jeeps, and Toyota Land Cruisers. More ground clearance (by far), smoother, quieter, more comfortable ride (by far). And, when the going gets tough, the Cybertruck doesn't disappoint. Front and rear mechanical lockers can be activated from the touchscreen, and they turn the Cybertruck into an unstoppable climber, through steep, slippery slop. I can only imagine what it could do with grippier off-road tires! In tight spots the maneuverability is insane for a big truck, closer to a Toyota Land Cruiser. I've been off-roading for over 40 years, and I've never seen anything like it.

[@TheKiltedYaksman1]

There's also friction stir welding, but it's normally an industrial use situation that doesn't have much application in a garage or home setting. But it lets you do cool things like weld two disparate types of metal, or even polymers, that you'd have to bolt, rivet, or glue other wise.

Great video Jared... I REALLY like the technology. I do have to say, the "easy weld" machine looks like something that was made in the 60's LOL The ability to easily make very thin weld lines is amazing. Yeah you can do it with TIG and MIG, but this is easier, cleaner, and doesn't require very much finish work. Especially from warping. I can see this becoming very popular here in the U.S, especially as the prices start going down like everything else does, after they have been on the market for awhile.

[@_droid]

The main problem with lasers is their "danger zone" is huge. Anything that can poke an eye out from across the street needs more than a bit of caution. Or set something ablaze from across the room, etc. Plus with the invisible infrared people won't even realize they're losing an eye until it's too late. The danger can be managed with a machine, handheld not so much.

We have been using laser welding for a while now. Bit expensive compared to a sprayweld. But seems to work good with soft metals.

[@Bobbycleff]

I had been a A level certified pressure welding procedure #9 (PWP#9) Welder for years I welded pipeline and titanium, which is probably the hardest thing to do cause you must keep-the purge gas over the weld puddle till is solidifies, but when you welding with that laser equipment you have, I noticed that you pull your nozzle and will cause weld buildup and less penetration . whereas keep nozzle tip 90° to 105 degrees facing toward area to be welded when using a fill rod so the laser light is creating a molten puddle and heating up the metal filler rod prior to just making deposit like in oxy/acetylene and TIG welding when using a manual filler rod (hand feed) anyways it works better. When welding metals that are easily contaminated by atmosphere gas , you may have to build a customized inert gas cup to extend behind the weld with steel wool inside it so it’ll disperse cover gas evenly over the cooling weld so it won’t contaminate . You will know a weld is contaminated by it having bluish rainbow colors in it after it has cooled.

As a generalization as much as all polymers are plastic, lasers are light. Being technical me, I will say that in terms of accuracy, lasers are photon-based EM energy.

My ideal would be a modernized acetylene-gas welder via a modified plasma torch, surprisingly which I've yet to see a viable option other than experimenting with my own tips and fumbling with feed air pressures.

Can you do any plastic welding with the laser welder? I could see how it would be possible. Same concept as with the one that just fuses them together and dosent use a filler rod. Just melt together and join two pieces of plastic. With the one that uses the filler wire, you could have a plastic filler material that gets fed into the joint. Can these machines be set up for plastics? It would be a neat idea!

Wow. YT suggested a video from a Subscribed and Notified channel for the first time in 3 months. Well done YT.

[@randr10]

When you started talking about it my head went right to body work, and someplace that does a lot of it. Probably wouldn't make sense for the home gamer given the cost, but could bring the cost of sheet metal work down when you farm it out too.

[@Ada..D]

It would be good to see a thermal image camera view of the various welders in operation, to see what the heat spread around each type of weld actually is on thinner sheet metal. Could laser welding cause less deformity when used in say, car body panel welding, etc ?

[@MrPruske]

Jared, ive seen you other places but now stumbled on your chanel and its on a topic im interested in so i guess you got s sub

[@cidercreekranch]

Great video! Note, laser stands for light amplification by emission of radiation.

[@PaulG.x]

Fusion welding is any process the melts the items being welded. MIG , MAG , TIG , Stick , resistance , friction , laser are all fusion welding processes.

[@raven54021]

love the tech but one thing you missed is why you need the ppe for a laser eye damage man warning dont look at the laser light very bad for your eyes

[@blainemilliron3870]

the light duty one might be good for a juller doing silver rings and such

[@Blackinterceptor999]

Depends on the size of the "Garage" if your doing custom RC trucks and cars, then sure, using this to build those small tube chassis for those cars and trucks would work perfect

[@Ma_X64]

Ultrasonic welding, oxy-acetylene welding, spot short circuit welding, vacuum electron beam welding, capacitor impulse short circuit welding, carbon rods arc welding (no current through a part), carbon rod nitrogen welding (like a TIG). I think there're more. *By the way!.. There IS "welding" with sunlight concentrated with a lense or a concave mirror. Never saw it as exactly a welding device but there was the Laboratory of Extremelly Pure Alloys" in Crymea where they had such an apparatus. They were melting metals with the sunbeam! Isn't it cool?

[@dean_c]

If you are going to try plastics be very careful as certain plastics can let off very toxic gasses when lasered

[@jtippin2001]

I was a LASER weld automation expert, Edison help with developing the schedule I developed for Nitrogen. shield gas. Much cheaper and prettier. Welding MGG safety systems. Micro Gas Generators for seat belt pretensioners. Millions of those welded, Push material is better for heaver material. Must replace the shield lenses more often. ND YAG what we used.

[@taurota1554]

Thanks for sharing and taking us along

[@morgansword]

I have seen those type of welder used with a robot. I have been trying to keep up on them and so far, I see most try them, the cost of consumables seem to just leave them angry if on a tight budget. I also think its going to take a while for most to fully understand this and keep it going as a first choice

[@stevenoe6395]

When are they going to be available to purchase I couldn't find the welder on there site and the ones they do have you can not just buy you have to contact hero that kinda sucks

[@hojo9115]

This looks like it would be great for home use. But I reckon it's gonna be real expensive. I remember when my boss bought a plasma cutter for us we thought it was awesome because we were used to using cutting torches during repair work

[@YellowAstra]

Less heat into material while welding means less problems at the end.

[@Yackhammer75]

The white safety glasses remind me of the glasses the oompa loompa's use in the tv room in Willy Wonka. I kinda want some

[@mikekozi-lester3887]

Hi Jared nice video 📹 and workmanship those are nice welders LASER ONE LOOKED GOOD

[@PsychoticusRex]

Culture shock: You don't need a ground loop, working flat on a metal table is probably holding you back. You might try elevating your work and possibly working on wood or something dirt cheap.

[@ronr344]

There have been $1000 China units out for over a year now. Plastic injection mold makers use these types of welders for very small intricate geometry for quite a few years now.

[@scoobysean555]

All the oldschool welders hate this as old school is best ...people dont like change 😂

[@dzzope]

How much power do they use? How much heat is in the piece vs mig/tig? (Thermal camera side-by-side to see how much and how far it travels through different materials) How much do they cost? How delicate are they? How clean do you have to keep the lenses and any thing special about cleaning them? How much to replace? Would love to see a few months of a test in a shop and see what it's great and not so great at everyday. (great to hear we'll see that) Looks super useful TBH, the interest is real though at the right cost (obviously much more expensive than a reasonable multi mode machine).

[@nirfz]

The S in LASER is for stimulated not simulated the T makes a big dfference! Imagine a tube where a particle is emitted by one end of the tube, hits the other side and that triggers ( *stimulates* )an emission of a particle in that end, and that goes from one end to the other and due to the nature of it, they will group together. Until the number of particles in a group is high enough that they can pas through one end. That's in a nutshell what happens in a laser, just that some people argue if light is a particle or a wave and for engineers it's both.

[@michaelogden5958]

Man, lasers have (obviously) come a long way since I was in college in the early 70s. Back then, a laser powerful enough to burn a hole through a wood 2X4 in about 10 seconds - was about as big as a good-sized modern refrigerator on its side. I wasn't into the electricity aspect of things, but I'm pretty sure single-phase 240V was WAY less than those lasers needed.

[@ruwithlee1970]

Hey Jared do a show on the Laser Rust blaster thing it looks really interesting I've seen it a couple times on KZbin!

[@TheQuestionableGarage]

We are talking about getting one sent over, they are still finalizing the air cooled versions

[@juangarcia-kq8zp]

What is the range of the laser? If you burn a hole in the base metal, will the laser burn whatever is behind the base metal such as: your table or your leather glove and then your hand or your foot or someone across the room? If you point the laser at a mirror (or chrome), will the laser reflect back onto you to burn your face or set your clothes on fire or permanently blind a passerby who is not wearing shaded eye protection?

[@DivineMisterAdVentures]

That's the Holy Grail of Heat Control - wow - it's almost perfect. (Nothing is Perfect.)

[@juangarcia-kq8zp]

Will the laser melt plastic? Can you weld plastic with the laser welder? What about white plastic versus black plastic or clear plastic?

[@erichkoehrsen959]

Great video and really cool technology. You should know that this info will send me down a rabbit hole doing research 😂. My 20+ year old Harbor Freight flux welder finally gave up the ghost and I’m in the market for a much more capable replacement.

[@TheQuestionableGarage]

As much as I would love to send you right to a laser welder, the Vulcan mig max might be an awesome fit. I’ve really abused the heck out of it and it’s just stunning.

[@craigbowley6783]

Brent up at half ass customs has one of those but it's the huge Unit and has a laser stripper on it.

[@markrowland1366]

Great report. Good demonstration.

[@rvarsigfusson6163]

Thanks for this go-thru..... A nice one..... But Nitrogen gas is used.... I did read in a manual to a laser welder ?name..... It was using a CO2 and for all metals!! That`s a plus to cut down the cost of buying a gas bottle for BIG bucks because of MONOPOLY.... A MAG welder can weld not so precise cut parts but Tig, Plasma and Laser welders are forced to have nice cut parts...... but now to days we cut things in a CNC but that was not common for some years ago. So comparing Laser and MIG/MAG is like apple an orange. A friend of mine did buy a Laser and I have to go on surprise visit....... few times!!

[@darylhudson777]

You did not mention Thermite Welding...example: connecting railroad tracks. Oxy-Acetylene Welding.

[@PatrickKQ4HBD]

I only got interested in metal working after I got my pacemaker, but before I learned that pacemakers and welding don't play nice together. This tech could be VERY interesting to people like me.

[@jvmiller1995]

There is a lot of advantage to using laser or rust removal. It is not as fast as media blast just yet but it is clean and can get to many places a wire wheel can not go. I think ten years from now they will certainly be into many home shops and most production shops. I never see them replacing mig or tig out right but then I do not think that is the goal either. Thinner metal they might one day surpass tig just because out of all forms it is the hardest to master.

[@georgeferlazzo7936]

Hello again, Jared Thank you for another Great Video 👍 I didn't know that this was even possible to lazar Weld. Thank you for introducing me to this technology.

[@TheQuestionableGarage]

Glad I could help!

[@scudzuki]

I call it TIG but the name has changed to GTAW (gas tungsten arc welding)

[@Trash_panda_real]

You also have explosion welding and thermite welding

[@oldphart-zc3jz]

It''s intended for autogeneous welding of thin stock properly prepped (cleaning with acetone like prepping for TIG is never a bad thing) which is outstanding for sheet metal. I suggest adding (many) safety warnings because inevitably some Bubba will blind themselves sooner or later by treating it like an arc welding process which it is absolutely not. Anyone buying one should as with any welding machine weld some test coupons for destructive bend testing to ensure making sound welds. A weld can look good (like cold wire welds) but not be good.

[@dave6501]

Thank-you for the video Chad. Love the team work with the boys. Keep it up .

[@VolkerHett]

Once you start repairing cylinder heads from vintage racing cars like the venerable Cossworth 2.5 16V in a DTM Mercedes 190 Evo 2, you might want to have a look at Alpha Laser in Germany :)

[@dwayneharris3874]

It looks like it would work very well for autobody work.
