- Опубликовано: 14 авг 2020
- I couldn't resist! Once the so-called "cold welding" videos went up, and everyone started messaging us about it, I had to go buy one to figure out what the real deal is behind cold welding. Is it real or is it just someone clicking a switch for an inch? Let's find out! #ColdWelding #ColdTIG #ColdWeld

What's with the nails? Really... WTF is with the nails? I can't watch this because of your nails!!
The fact is - you saw the nails which means you'll recognize those nails when someone tries to steal this video to promote their product (watch the vid if you don't understand).
Yes. I also have a daughter. If she wants to do my nails or put makeup on my face (which she has in the past), I'll totally sit still and become beautiful. She actually would have done better on my nails than I did for this vid.
If a black marker on someone's nails ruined your day - you have some serious issues 🤣. I appreciate the views either way.
that's ingenious!
You’re pretty! Stop it!
You can have custom fingernail decals made with your logo or (ie stolen from) and restrict access to you and your sproutlettes. Sign me 'Father of ALL sproutlettes and Papa of mostly grandsproutlettes'...
i figured you made your nails looks so igly that no one would want to steel it
Now my YT ads are about nail health products! Thanks....
Watching this vid in a pitch black room is like being flashbanged non stop
Fr
It’s all flash and no bang
lol

@@azligckshibson870 why?
This machine is the equivalent of cooking a chicken at 1240° C for 15 seconds
that was actually a pretty cool way to compare it to something respect+
You mean ppl don't do that?
Isn't that 'Cajun Style'? I've always called it 'burnt & raw' but that's just me....
That's why my kfc is so dry....😆
Yeah, then the best meat would be the one between the outer carbonized skin, and the inner frozen tissue.
I own 2 miller tig welders & a multimatic 220/ac/dc & a Lincoln mig w/spool gun....I bought an Andeli cold tig welder for $450. Came with 2 torches (wp-9 & wp-17) plus a simple trigger foot switch. For the specific type of low load stress, high precision tiny parts I make it is fantastic. Limited application for sure, but its incredibly easy to use & fully programmable in microseconds dwell, amperage, cycle(in pulse mode), preflow & postflow. Fantastic for precise tacks that are followed up with silver brazing, short burst spot locks things in place without oxidation & fluxed silver brazing flows beautifully over it. I regularly use it for very thin guage stainless sheetmetal parts as well & never burn through... All you do is regulate your trigger finger timing (or set simply set it to pulse mode) & you can get perfect weld penetration. I see so much hate in comments sections I really don't get it. (*Except it is made in China...& there is an irrational hatred of their products & manufacturing capabilities)
Good review on this I have been picking up a lot of kitchen stainless jobs and was looking at this machine myself!!
Agreed,its for a purpose,not building aeroplanes and as Flatbob says it works well.
My Unimig Razor 200 acdc tig has a spot function which does exactly the same thing,its not new,just another option for your particular circumstance
Imo, "cold welding" is just a gimic! I was doing this 35 years ago. I had a spring loaded on/off micro switch taped to my tig torch, and I would either preset my amperage or use the pedal. The switch would completely break the arc/amperage. I referred to the process as manual pulse.
spot on mate so did i been air craft approved for over 20 years and asmi 9 and 6 g app
What do you mean by gimic?
Yeah - I'm not professional but I used to make some custom decorative pannes that had NOT to twist or buckle so I just used to pulse the trigger on the TIG welder.
So there was nothing cold about it - only it did not allow time for heat to build up and the metal could dissipate the heat.
It's not comparable because because here it's electronically controlled at high amperage and very short duration that's perfectly timed. You can't achieve that manually. It's like cleaning fuel injectors with a homemade switch that ruins the injectors vs. a designated device that opens them for a split second just like the car ECU.
@@anancapcat4221 Also known as bullshit.
It's wintertime here. My workshop is not heated.
All my welders are cold welders.
Ah rather you're the cold welder.
Best comment 😂
Hilarious
What model welders?
@@deankendell6644 No, certainly not. None of them are models.
"Honey, they didn't have any of the long rolls of aluminum foil at the store." "Hold my beer!"
Is this not pulse welding or arc welding? Is cold welding a new name for it?
@@democracyforall this is not real cold welding. Real cold welding does not use any heat.
totally going to steel/ borrow the "hold my beer" thing for Aloonium foil "cold welding BS"!! (bringin back Bugs Bunnies pronunciation of Aloonium)
Hahaha this is gold!
Haha very funny...😁😆
I'm happy to have watched your testing of this "welding" process. You have proven what I suspected. I have no problem with the nails. Thanks for posting!
Nothing like a narcissist looking for a way to make some money ....which at 1,604,514 views ....he is doing.
This guy is a clown. The nails is evidence of this.
But as far as really understanding the concept of APPLICATIONS ....he really doesn't get it.
I note he mentioned NOTHING about AUTOGENOUS WELDING .....which is what he was doing, almost throughout .....and very little mentioned about weld strength, prepping, or penetration.
I also note it took him up to the half-way point to start talking about "PULSE" ....which is exactly what this is all about.
If you take the heat source away, ....the material cools. It is NO LONGER HOT AND MOLTEN .....MEANING IT IS NOW "COLD".
But if you turn the audio off, you can SEE some interest welding APPLICATIONS going on .....which the audio portion is a god-awful distraction.
.
The “spacey spaciousness” footnote to the Cold Weld definition made me a fan for life. Well done.
I want one! But then again I never needed a backhoe until bought one. Holes all over the place!
😆
I agree, I didn't know I needed sticks of dynamite untill i didn't have them any more.
Haha. This is the best comment on the internet
Same
Don't put them in your back. Can you dig it man?
I could see this for a jeweler. Neckless, bracelets, etc. Even setting stones. Or if you wanted a second machine to tac sheet metal without fear of melting.
Or maybe prototypes so you can break welds quickly with less loss
Jewelry, and also chainmail!
Eric bloody good idea
Or metal frame eyeglasses (or sunglasses) repair.
Yup, i wonder if it could weld (or rather join) thin silver (0.5-0.8mm) plates?
You can buy a version without the gas and various amounts of capacitors missing for 60 bucks sold as a jewelry welder I have one works okay once you put in the capacitors.
If you want to look into it I have pretty much all the videos in a playlist on my channel and I made a video about modifying them myself, but it's not really informative.
I found it quite useful for mixing small items. A/C pipe leaks, for example. Leaks are small, pipes are copper, valves are close by.
i use oxyace for ac leaks, first get qualified guy to empty it, weld it and have same guy fill it. Heck i need to qualify in those too im plumber and i only can install the systems but not fill them or mess with them
Would also be useful for figurine artists
The arc sounds like the old miller snap start which works very well. Super for small tacks.
I never seen any one weld aluminum foil together before. That was kinda cool. Cold weld could be termed as a Hobby craft welder
We used to do that in tig class. Its good practice for heat control.
exactly how we practiced as well learning tig!
This isn’t actual cold welding. It’s just low amp tac welding.
learned that trick way back in 1985 the trick is, bet ppl and tell them they can set up the machine ac or dc +/- any amperage there choice and you will weld it i must have made $1000s of dollars since trade school.
Amen brother, Amen
The Chinese people sure DO understand the word "copyright".
It's the right to copy. 😎
Forced Technology Transfer is an interesting arrangement. They will manufacture stuff for you cheap, so long as you sign over your Intellectual Property to the CCP. Then, everyone (Chinese Manufacturer) is free to copy the other. That's the deal. Its completely transparent. Take it or leave it.
😂
It’s a copy? Right!
Well, I've seen "consumption rights" used around when they were trying to say "consumer rights". I can just hope that is a translation mistake and they actually know the difference...
You need left copy also
I've been a Blacksmith for over 60 years had black nails many a time, like your vids learn new things everyday never to old to learn TKS God Bless you and your daughter
A nice, precise and short tutorial. Thankyou for your time and expertise.
That thing would keep your auto darken helmet scrambling to keep up. Kind of a war of micro seconds you might say.
If there was a way for the trigger to also trigger the darkening you basically wouldnt see anything going on, just metal fusing since the darkening is so short and the arc so short
@Todd B In a serious setup you're looking through a 10X stereo microscope and it has an automatic shutter to protect your eyes. They are very sweet to use. You can hold small pieces with your fingers next to the joint- THAT'S why they call it "cold welding". You can run along about one hit per second.
@@craigwall9536 Could you elaborate on this, please? Your comment has well and truly caught my interest, sir.
You can set a delay on most helmets, so it can stay dark for 5 or more seconds.
I have Optrel Crystal 2.0, it does not triger when trying out "cold welding"
Looks like someone was reliving highschool with NiN, Marylin Manson, and Lincoln Park. I havent seen nails sharpied black that poorly since I did it in the lunch room bored af. Love it. I'ma go cry to some Dashboard now...
Im glad you cleared up this cold welding thing.
thanks for making this consumer oriented video. I was very interested in COLD welding until seeing this. Much Love!
I'm glad someone took the time and money to look into this!
We need him to do a follow-up video showing how this can be accomplished with a mts 252 or 275 pluse DC TIG welder
@@772777777777777 yes i need this is video
@@billelnaruto5390 mr tack....can you follow up this video...
I watched a few cold welding video... and observed a few things for thin gauge mild steel ie .035
The setteting are preflow
Ramp 0 tig base amp equal sheet thickness ie 35 amps..tig base on time is low..20-50%, freq pluse is equal to amps ie 35 pps, tig base % amps is set low? No down slope...tig end is very low, pre flow 3 sec
I would experiment more but got not argon to play with st this time.
Just look into tool and die (injection molds) repair business. Example: SANWA SW-V01 machine.
The first definition you mentioned is also called diffusion bonding & we used to do it @ Pratt in a vacuum chamber welding turbine components together. metals were very thick & clean , pressed together with many tons & sometimes had an ultrasonic vibration applied to one part.
RIP to the people watching this at night lol
🤣🤣
HAHA, When i first watched this finger nail and "sparking" welding , reminded me of the Mrs.welding youtube channel bragging of "cold welding" lol.. But you do it so much better. .lol Good job..
As a matter of fact, it is actually legitimate process that my Kemppi Masterig MLS also has_ _but its called microtack.
And it is meant for tacking very thin parts without penetration, without the need of grinding tacks, need for purge gas and so on.
Are u using shielding gas for the cold welding?
@@ianmoore525 Shielding only one side like regular Tig welding, tack welds only, so there is no full penetration, thus no need for back- purging.
Main downside is, ideal fitment- absolutely no gaps allowed.
@@hdjawa You need to figure out how to feed filler wire in, to close the gaps and add thickness. I think it's better with gas. Argon.
My Kemppi at home has a similar setting called "Micro Tack", it works pretty good when tacking and not being able to hold wire with the other hand.
Yeah , I've got masterTig 335 AC/DC , welding some 0,8mm on 120A 30ms ,50ms continues program .. amazing job
My curiosity has been satisfied. I see these videos on tiktok but was lost in the comments finding the name. Thank you for taking the time to explain what it is. I was fascinated by how the sharp tip on the hand tool could do the weld but then be sharp again after each tack. I thought if it was being melted then it would end up bulbous like soldering wire looks.
As an old school Coded Welder in ZA i do appreciate your Videos so Much cause at 71 Years of age still Welding everyday of my life i have no rye Bries for anything Chinese !! In Fact i don't understand why i were not Born in USA ! Keep up the Good Work , GOD BLESS
Maybe this is something for sheetmetal repairs on classic cars, because you dont get the destortion, that you would get with normal TIG
This is nothing new. Single "shot" TIGs are used in the injection mold repairs, for example.
I was thinking this too. 🤔 I wonder if it would be strong enough to not crack later on down the road. (Pun intended)
One summer while building demolition derby cars, my cousin had laid a weld but the machine wasn’t set right. I told him the weld looked cold so the dipshit touched it 😂. He said “no! That’s hot af!”
lmfao !!!!!
Well hell remember that one for sure next time someone tells him his welds are too cold😂
ROFLMAO.
You can wear gloves. An apron boots all the protection equipment and that shits still going into your shoes.
You see a guy welding he stops and starts hopping around you know wtf he did.

Roflmao
Thanks for the clarity and honesty. Im looking at a project that will likely involve repairing corrosion on Aluminium hull , what welding method would you recommend ?
Love your nail work!
I came for the video, I got the popcorn for the nail comments. :)
I can't find a single negative fingernail comment.
We use a "cold welder" professionally. It's a professional machine, somewhere in the 15.000 Dollar-range. This machine is used to tack up woven wire meshes with wires for high-temperature fuel cells (SOFCs). Other possible applications would be jewellery or micro-parts. So yes, there is a field of applicaton for these machines and yes, they work really well. But, almost nobody needs a machine like this at home. I really like the way you pointed out the "cold welds" it produces and yes, on homegamer-sized parts this will mostly be the case. I this it was This Old Tony who showed, that the HTP 221 has a "spot" option for tacking small parts AND it is a fully sized AC/DC TIG-welder. So, if someone had to deal with such situations, that's the go-to machine for the homegamer and also for the fabricator.
The machine in this video can be also used as a normal dc tig welder btw
$15,000?
Or do you measure tenths of a penny...?
@@sourbrothers73 15000 :) That "." vs. "," thing always bothers me. Even though I regularly work with people from over the pond, I get confused with it every time.
@@Gerhardter lmao just ball busting
Lmao did you buy it from "I saw you coming" welding supplies
Thank you, you answered alot of questions in a short time, most people ramble on...
As someone who is very very average with welding I watch video's to try and improve my lack of skills. Having said that I have welded 3,000lt water tanks that held together primarily due to doing back over any bad welds with more wire and accepting I had to do it repeatedly to make up for lack of education. I love watching a true craftsman or woman explain while doing and the explanation usually makes me feel a whole lot better. Loved the vid and the nails made me go WTF then figured you had a daughter. I remember similar activities with my oldest who is now 19.
That moment when you welded shorter filler rods into longer ones together, I was like wow, thats effin genius man. This man will single handedly bring down big filler rod
Do it all the time.
@@michaelszczys8316 Same here with my alloy 602 CA nickel alloy rods, at $36.00 a pound I waste very little of it.
I run kemppi welders, the rigs have a micro tack feature, works extremely well, once you get it dialed in.
Never heard it called cold welding.
Fyi, I met you briefly at fabtech last year, you were too busy to be interested.
I have a small sheet metal shop in Queensland Australia, and enjoy a lot of your videos.
Yup, me too, micro tack is perfect for one handed tackning, it also makes it not too hot either.
It's just a bad translation from Chinese to English. We can see in the video what it is... who cares what words they use.
You clearly earned my thumbs up and I subscribed. I like your style.
Good video. Sometimes when I have to tack weld really thing stainless sheets together, I use high ampere and just push the button quickly. Connects the both pieces easily together. Then fully weld them "normally"
One of the Chinese videos I saw showed a guy doing that stuff with a busted cup-- about a quarter of it was missing. That probably makes the process a lot better.
I used a kemppi that haved a spot/cold weld option, I used it to weld a stainless steel guitar in like 1mm thickness sheets so I need it to be cold for minimize the heat deformation
After first hearing about this process I tinkered with my TIG welder and found done great success fusion welding thin stainless using DC pulse with very short pulse. From memory I was using 120hz with 4% pulse 100/10A - you can really run along a butt, lap, or edge joint quickly for non-structural metal gluing.
Yes, people are getting so confused about the bad translation from Chinese to English ('cold welding'). Really, it's just a nice spot weld that's very useful for certain situations. Depending on the situation, it can actually be strong enough to never break, which is all the strength a weld needs.
Thank you for explaining all of this ,...
Thanks for clearing that up. It's been keeping me up nights. Well, not really. But I did kinda wonder what it is a couple of times.
Now I understand the welds on the cheap Chinese motorcycle mufflers
This looks like more work than doing it the right way lol
@@Mrfitrider1 But you don't need professional to do it. You give welder to a kid, and pay him dish of rice a week.
Dude this guy just doesn't have a clue what he's doing with a tig welder lol
@@craigelkin53 So, he faked it until he made it....hehehe....Seriously, I think he has quite a few clues.
I bought a Grom with a Chinese exhaust, and it broke right in half on a weld like these. Found the pieces, and could tell there was so little penetration, you basically could've painted on the "bead."
I enjoy the information you are more informative than most I'm learning from other people's mistakes before I put my toes in the water will say
I noticed that Ms. Weld’s eyelids are special. She uses them to block out the dangerous arc flashes. She really is amazing
Great video as always Justin! As much as i like the new "vlog" style videos with the truck, I really miss this style of video where it just seems like its you and the camera knocking out some cool and informative things!
I can see the usefulness of this process, especially on thin aluminum. It would be a cool function to have on every GTAW machine.
Im pretty sure i can set my pulse tig up to do this, at least i can get it down to a few amps and it can do 20khz blips. Now i gotta go try..
Yay, somebody has actually bloody explained this (finally hit the bottom of this sodding rabbit hole) so cheers for that...oh and you even cleared up the nail business also...double kudos sir.👍👍
This would be great for putting together thicker electronic stuff, as a slightly faster alternative to soldering. Just blast the wires with the arc, then flow solder on. But then again we have bigger solder guns and torches just for that. Maybe making metal jewelry or sculptures where the thinness of the weld is actually desirable?
For me this would be great tool. At least for making my RC models. Small parts, thin metal. This seems to be very easy to use.
Me too. Metal toys? Small kid bikes? And some simple diy in the house that needs to be weld.
Ring and jewelry
Yep it's made for small parts such as for rc hobbyists and jewelry👍
Injection molding, repairs - this is real application of these "toys" (as clueless folks say).
@@qwertyasdfghjkl9604 I am doing so ten years ,recently the name changes to "cold Welding"but before that it was micro-tig and the first machine is from Europe.
Pretty cool to see the foil weld together. I thought it would be too thin. 👌 💯
Thank you. You seve me some money, I was about to buy it, but first I diced to investigate a little bit more.
So its just a fancy name for spot welding...I'm still new to tig welding but I've learned alot watching you and others and lot of practice
I think the best case use for this welder would be for art, or making intricate things out of metal.
TIG welding is a good method for a lot of APPLICATIONS ...art would be good. But ...you don't need THIS one welder to TIG.
@@taxicamel What would be a good welder to buy so I can do this?
@@wiggsan This one (in the video) is Andeli TIG-250MPL.
@@hxhdfjifzirstc894 Thanks!
Forty years ago, before auto helmets and inverter welders, we used a gouging rod sharpened to a point to produce very short/quick arcs to fit-up 20 gauge stainless sheets for bench tops, face-shield down, but shade-visor open, and just blink for the flash. A manageable risk.
Then, do a few very small tacks with the TIG before the weld run.
We also had an assistant trickle water on the back of the weld during weld run to keep the heat under control.
Sheesh, we don't do any of that now with current technology.
Try that sometime; sharpen a gouging rod to a pencil point for very small short arcs. But have a very clean shade glass or adjust your auto helmets to suit.
Or just blink.
I was wondering if anyone ever used water cooling for this kind of thing. Thanks for the info.
First time viewing and this vid was awesome man great job definitely subscribed now that foil weld was something Iv never seen before thank you for doing what you do wow
I know I'm pretty late to the party on this one, but I thought up a challenge for you with the cold welding. Produce a satisfactorily strong weld with tubing and show us what it took to pull it off, or how much you had to put into it before ultimately deciding it's not possible. Keep in mind that I haven't spent more than maybe 3 minutes searching before deciding I had an original idea so forgive me if it's already been suggested or done, haha.
I always thought this process is designed for cosmetic purposes and not structural. For an example, a range hood made of thin stainless still. Or anything made out of thin stainless sheet for that matter.
Hey I have a TIG welder AND I can't weld
David Guyton so sale it.
@@DavidGuyton or send it to me, i need one
Naaah once it needs to hold something together is structural.
About the only thing it’s really useful for.
What a great vid. I legit have been seeing those "cold weld" videos and was confused. Makes you almost question what you know.. Lol
Also for half the video I legit was confused with the painted fingernails and the watermark. Great job haha
So you're not confused with the finger nails, well I still am whats the deal ? Watermark ? I'm lost.
@@haroldleon7249 there are a bunch of Chinese "Cold weld" like tiktok style videos on the net. And they have the weird watermark and sometimes its a person with painted fingernails.
Thanks for the video explanations. JD
Dude awesome, answered so many questions!
This type of welding has been used here in europe at least for quite some time (at least over a decade, so certainly not new).
Just not in construction welding, but other, more technical applications.
There are also specialized versions with moving tungsten electrodes.
Where do you think the chinese copied it from?😅
Cold welding or "micro-tacking" has its use for, you guessed it - tacking pieces together. quick and simple.
I would not use it for anything structural, however, if used on thin materials (< 1mm), like for bodywork, you can negate any warping that may occur.
thats what I was going to say, it will do great on bodywork
Only a 30 seconds In to the video and I'm realizing that this is the video that explains the other video I had just watched the "Mr.Tack" was a nice touch hahaha I like your humour
So useful for very very small things but not really anything larger kinda what I thought when I kept seeing these on it shorts and having been a welder for awhile now.
I can see this welding process being usefull for hobbyists. Especially for those that work with very small parts. Thanks for the enlightenment on the whole cold welding process.
I can see where it would be handy for sheet/body work. Low heat joint means less warpage during tacking/welding.
thats what i was thinking seeing as i just did a load of rust repair xD
Amen
Thank you...well presented and analyzed
Pretty cool
Haha
Great work!
Keep it up!
“there’s nothing funny about molten metal so don’t be a dumbass” earned you an instasub. 😂

He's forming a BAD habit.
It's those black finger nails.. They Just makes people want to hurt themselves
Don't worry, he lives on the edge.
Good vidjoe. I might be to late for suggestions but here it is. I’ve seen a process where surface pitting on fine steel parts (firearms), were repaired using a high end laser welder. I assuming they have a vacuum box. The pitting on the part is fine. What they are doing is putting a very small cross thatch of spots and then resurfacing using files, stones etc to smooth the whole thing down. And then bluing or whatever original finish type.
Very specific application of antique pieces. Heat distortion is a big deal, and amount of filler if any is minimal. I think I will practice on a garage sale BB gun before I would attempt this on grandads Boar war rifle ?
A laser welder simply uses pre/post argon, like a TIG welder... there is no vacuum. They can use filler if they need to. The only difference is a beam of light melts the metal, instead of an arc. Of course, the laser welder is going to have optics to precisely aim the beam... with crosshairs like a rifle scope. If you crank the laser up really high, it'll blast a hole straight through a coin in one shot. Big lasers are used in the military as weapons.
... ...2:45... That hex nut sure looks pretty warm... and the .035" wire...at one time I used to buy 50# boxes of .030". I don't know if they still make it....it was a Lincoln product...
I do appreciate the time you take to produce these videos.!
Best informative video I've seen! 👍
Thanks!
Hey gang, my lincoln ranger when hooked up as a tig welder with power at zero can scratch start and weld the sharp end of razor blades. Believe it or not it has a rather stable low amp dc arc.
Ok now that I watched this video I decided I really don’t have any use for it. My small welding business is all about penetration. And wanted to add Keep up the videos your videos are very educational and interesting 🧐. I wouldn’t be surprised if you already are a welding instructor for a Tech college 👍🏻
Thanks for the explanation!💐
Thank you
Best explanation yet.
Dude ! You're freaking me out!
I thought I clicked on the Sharpie Goth Welding channel.
HAH, before I looked in the comments, I was like he must have done the nails so the welding shots don't get posted somewhere for advertisements. Great idead, but at first I was a little thrown off by it.
Love it man! Lol the sharpie nail polish is the cherry on top lol nice work!
You Vado the same with high frequency tig and set it to tack weld. I’ve done this 20 years ago. I’m always a fan of welding stainless steel sch 80 pipe full peno
My first thought at the beginning of the video was, wow, changing up the video format here and diving into some informative aspects. It was certainly that, but then transitioned to satire all while maintaining an objective stance.
Great video! Very entertaining and also quite informative. Thanks for sharing
i could see where it might be used for small scale modeling or adapt it to 3d printing unit with a wire feeder.
With a hellavalot of fans to keep the part from melting while printing it, so you don’t have to wait 14 years for it to cool down in between adding filler material
Very informative video, thanks!
I have the same model. Excellent welding machine.
As a woodworker, who could benefit from occasional welds but always finds a work-around to avoid welding, the thing that appeals to me about Cold Welding is how simple it appears to be. I attended welding school and certified almost 20 years ago, but ended up going another direction. The thing that prevents me from my welding when I'd like to weld, is the complexity of all the necessary equipment, setup, and the knowledge that goes along with it (I've forgotten most of what I've learned). For example, if I want to weld two pieces of scrap together, I don't want to have to figure out what type of metal I'm working with, order the specific weld rods, etc. This seems to cut out the entire step of selecting rods, and creates a neat (if weaker) joint. Also, it appears that you can join dissimilar metals rather easily.
If you're gonna weld wood I'll gladly watch the video😂😂 . Seriously, this process is nothing more than short pulse tack welding. I've seen similar function on reputable brands such as Kempi etc for a number of years before this 'cold weld' bullshit.
Mig welding the the answer you are looking for then!
Its a fair amount easier to Mig weld than Tig or Gas weld. You could be good enough for hobby type stuff in Mig by watching some RUclips videos.
Don’t have to worry about selecting rods, just take two pieces of steel and go do it. You can find pretty inexpensive Mig welders at Harbor Freight and places like that.
This ‘cold welding’ is basically useless. If you tired to do this the piece would be about as fragile as if it was stuck together with Elmer’s glue. You could really only use it to weld things you wouldn’t be touching or moving. Like a model of some kind that is never coming off of a display stand.
What I know about the cold welding is about the nonexistent layer of oxidised on metal. Which usually occurs in outer space where there is a lot of that thing happen to the machines up there.
This is just a bad translation from Chinese to English, not the kind of cold welding you're referring to.
Thanks! Great, honest information!

Yes. That is the purpose of those machines. Example: SANWA SW-V01 - this is the real deal, not toy.
Im glad you made this video. I understand what's going on with the process, but I also understand if you fuse the base metals without fillermetal (particularly with the "jogging" or pulsing on and off) the weld will almost always fail due to thin weld zone areas, inclusions in weld and poor fusion.
With this method sure, welding without filler with tig is good enough to meet standards for balcony Railings or some other stuff that people can lean on. Iirc its 1kN per meter or something.
@@readordienn that would depend on what metal the handrails are fabricated from. I would not recommend welding ANY handrail without the proper filler rod AND joint preparation. Stainless is probably the only material, but if there's any gap on the fit up when welding said handrails, you are going to need filler wire.
@@yourdrummer2034 ah forgot to write. Ss304 no gaps, holes filled if they appeard
@@readordienn sounds legit.
