This isn't 'cold welding', it is TIG 'fusion' welding (without filler rod in most examples). Miller Corporation explained many of the pitfalls of 'fusion' welding as much as 16-years ago...such as the tendency for cracking, very superficial penetration (1/16th inch), insufficient weld strength, and when it comes to aluminum, the tendency for it to crack upon cooling. Cold welding is NOT shown here...cold welding occurs in a vacuum, and is a completely different process (as different as TIG is from MIG or SMAW).
This is ' cold ' welding in that it is done so fast that there is no real heating of the metal beyond the weld itself. It is only good for teenie weenie parts that are so thin that they heat up almost instantly. Anything of any real size just doesn't get any real bonding unless they go over it a bunch of times then it is not very much ' cold ' welding anymore. It really is ' tig fusion spot welds ' that you might do by just hitting the pedal for an instant only it is more like holding the pedal all the way down and turning the whole machine on for half a second. All it is.
For Cold Welding, I thought the prerequisites were: Being in a vacuum, the metals being extraordinarily clean as the cleaner they are the stronger the weld. I knew not to expect too much but having the title the way it was I thought some information would be given. If anyone can break the video down I’d really appreciate it. Also if you can clarify if there are two different versions of cold welding.
There’s not two different forms of cold welding. You are right about the vacuum but not only does the metal have to be clean but also there can’t be a metal oxide layer around the metal. They call this cold welding because you aren’t applying direct heat over a extended period of time hence why these welds break very easily
@Gus Good for light duty welds only. You know like sheet metals and such, did a good job with the copper/nickel (braise) alternative. There are only three types of welding- s.m.a.w shielded metal arc, fluxcore- MIG, tungsten- TIG. Also (Aluminun) but this falls back to TIG setup.

So it's a double-amperage TIG welder with a MICROSECOND PULSE timer. It doesn't show but it's using 100% ARGON (mandatory). The reason it's called COLD is that there is no hot puddle to maintain during a weld - and there is no feed rod. The bond is technically a weld because the base metals are being fused - the lowest temp first. This is an inferior weld for strength - but you have here a highly viable METHOD that is far closer to "hot" welds than it is to any chemical bond or mechanical fasteners. ALSO it seems AFAIK UNIQUE in terms of joining DISSIMILAR metals. Would be cool!!
@@darklight4889 Yeah It would be great for aluminum sculptures especially - really anything that isn't "massive" that can benefit from extra super-neat weld joints and obviously mixing metals would be cool.

One tiny worry (with heat, dust, voltage & amperage issues) would be to ensure the high-frequency radiated power is properly isolated and isn't going to shorten the lifespan.

Fusion, TIG Fusion welding is got to be one of the cleanest welds there is using the natural ingredients of the part. I learned how to Fusion weld with a torch back when I was in school as a kid funny though my teacher couldn't break the weld that I made he could only break the actual Steel. Thank you so much for sharing
Nothing about this is cold welding, it is tig welding where she just taps pedals once fast for quick pulse of electricity. Any metals can be welded, the properties turn liquid and mix together to form a new alloy. The trick is will it be strong or just appear a copper pipe is welded to steel. She has to put the 2 inside each other because end to end they would not stay connected. This is click bait to get attention and nothing more.
Agreed. Cold welding is where pressure causes fusion. As in the occurrence of overtightening certain types of threaded matarials.... Titanium being one of them.
TIG fusion welding is very useful for taking the place of glue, tiny spot welds, and for tacking/positioning. It's great for attaching thin parts where cosmetics are critical, but strength is not. I have never heard a "cold welder" claim their welds are structural, so there's nothing to argue.
This is not cold welding. This is tig welding on a spot weld setting. Cold welding involves pushing metal together at great pressures and them welding together by the molecules exchanging atoms at the surface of the metal. An example of this is that you leave a block of lead on a block of gold after a week they will weld themselves together just from gravity. This can happen with gold and lead because they are similar but other processes need pressure to do so.
@@rduse9197 although this is not cold welding, cold welding is real. It is something that happens with pure(unoxidized) metals in a near perfect vacuum. They will naturally bond together. the astronauts who work on the space station have to have ceramic coated tools because of this problem.
@Timothy Wess Ceramic tools in space. I was unaware of this, but the only thing I can think of is there is no shielding from the Sun as a radiation source. So through electromagnetic radioactive force, metal tools either magnetic or highly conductive can but slightly ionized causing the molecular bond to be in a semi-solid state....but why wouldn't the laws of thermodynamics take place? The tool should not only weld but also heat up to an extent... unless the laws of physics are different in space's vacuum. You may be able to glue an object to another like solder, but as to fuse into the other metal and realign it's crystalline structure, I don't think that is possible and I would definitely not trust its strength or integrity.
no. cold welding is when you have a super clean surface that attaches to another metal surface without it being warmed up in any way, its possible to do with gold, explosive joining sort of utilizes "cold welding" but with a lot more pressure on it
It's actually Pulse Welding. You send a high current short duration pulse. For pipe to get a strong weld you need to be able to pulse weld the inside seam as well.
For a pipe to weld with strength you need to do a root run. As you pump in the filler you'll notice a small hole that looks like a key hole. As you pump in the filler it developes a type of run which is also purged internally at the same time as the filler is applied from the top through the Keyhole effect. Once the weld is joined probably 2 CAP RUNS are done over the root run deposit. They are a little hotter allowing the cap runs to help suck up the lower root run into the CAP RUNS...this is where the strength of the weld happens. Some seem to favour " Walking the Cup" creating a one seam that is just a little wider than the 2 CAP RUNS. Walking the Cup can make the weld look better visually. I favour being effectively, leaving a 1st Class result. Per industry Standard. There is no inside welding to smooth things out. Unless it's a robot sled doing Pipe lines. I've seen root run leave Haemaroid like hangings inside food grade tube joins. All has to be cut out...&...not from the inside I assure you.
This welder is a absolute piece of crap. None of those welds are strong enough to hold anything worth welding. You can break it apart with your hand in order for a will to be strong, it must fully penetrate the metal. This has zero penetration. It's garbage do not waste your money
Muy interesante pero los que nos interesados en ese tipo de soldadura necesitamos más información ya deperdido cómo se llama la máquina o de que tipo es 😁
Как быть с зоной термического влияния, где концентрируется напряжение возникшее от кратковременного разогрева и быстрого охлаждения сварного шва и основного металла?
The real problem is it isn't anything. These are just tacks but every single tack is completely edited to look like an instant shot but that's not how it's actually done. So it's wrong and misleading and also useless
@@valkenburgert no for some specific uses this can indeed be useful, artistical use like you said, or for fill up welding on parts where you want to avoid as much heat as possible. But for real welding this is not good.
@@UkanlosSmasher For real welding obviously not. But would that render my applications “bullshit”? Joined a welding forum too so not talking purely RUclips but definitely feel the welder community is not the easiest to access. I think experienced welders forget how mental welding is to the general audience. Loads of people find changing a lightbulb quite scary 😂 I will start to weld by lack of good (practical affordable) alternatives. But trust me I’ve looked. If someone looks at cold welding they are most likely scared of welding. Welcome them, be nice. Laughing and calling it bullshit doesn’t help. It took me forever to figure out you need gas and an expensive machine for “tack welding” like this. Anyway, totally unfair to call you out, could have been most people here, so please consider this message to be directed @all. Just trying to stand up for the noobs like me that will take interest in this nice, safe-looking, easy way of welding 🙃
@@UkanlosSmasher I got that in the end 👍 My point is that loads of people watching this are trying to avoid real welding. Most likely since they are intimidated by it. I still am 😊 They need reassurance and explanation. Being ridiculed doesn’t help if you’re new to something and people believing this movie will be new to welding. It’s the target audience…
@@jerrylvega8446 this isn’t literally cold, it means that it doesn’t dump a whole lot of heat into the entire part. If you have a tig machine this function would be called Tig spot.
@@hetrodoxly1203 I don’t know. It seems like a good weld. But as someone pointed out it is superficial. If you could do it from both sides seems like it would be good on parts not too thick. I liked the welding track. At least it’s not chicken shit. Seems ok for lighter stuff actually which is desirable.
@@whereswaldo5740 As a retired welder in all it's forms i can say with all certainty this would fail all known tests, these results can be achieved with a standard TIG set.
Call it what you like, but metals (mild steel, stainless steel, aluminum, brass) don't melt when they are cold. I've been a welder for 55 years and I've seen almost every kind of welding, in all cases the metals have to be melted. Lead/tin solders melt at the lowest temperatures, a couple of hundred degrees, still hot enough to destroy your skin if it were exposed to that temperature.
Yea I noticed the tungsten tip looked weird. I put mine in a drill and use a carbide grinding wheel. Hers looks shaved almost like a pencil sharpened with a razor.
@@duncanweir8773 Seems like it would be good for lighter stuff like expansion chambers on dirt bikes or replacing sheet metal on rusted out auto body. Or things I would want to do. Not actual welding but seems useful.
As a pro Welder for over 30 years I can say this is a long delay pulse welding and is a fun way of welding for cosmetic looks for the home hobbyist. Nice for you to take the time and demonstrate . I'm sure their are going to be many people influenced by this video. Just to say as mentioned in other comments this only gives about 30% to %40 of strength depending on materials used and has a lot of weld pool shrinkage and so makes it no good for parts that need to be strong. Example Steam pipes, as in no time there would be so many leaks.
as a person who has been around a lot of welding through work , whats the difference between this and a TIG? this looks a tig welder to me (but of course just because it looks like that to me doesnt mean it is)
@@antaLord It is still Tig welding but without forward heating. Well the Chinese are calling it Cold welding In welding terms it is a failed weld. But cosmetically looks and performs ok on decorative stuff as shown here and these items don't require structural strength and is just to look good. Meaning this Cold welding saying is a spot weld feature on the Chinese welders that are being marketed as if its a new idea of welding, in fact its been around since TiG machines were invented, It was a way i started to weld a long time ago on very thin metal. Almost a tin foil for British aero Space as forward heat would burn it to nothing. So If you have a TiG welder with a Pulse feature, your more likely are able to change the frequency( Pulse duration ) to a very slow rate and so you can do the same. just turn up your AMP's to around 100-120 for 1mm to 2mm metal. you may have to tweak the up and down cycle rate to, also you don't have to use full Argon, you can also use just Co2 or a Argon mix as their is no burning for oxidization
@@spudnickuk so the slower the pulse, the thinner the material you can weld without melting it entirely? I'm thinking about learning to weld watch cases/parts using TIG as a more affordable alternative to laser
@@kevintanumihardja3881 It is not just about slowing the frequency to achieve thin metal welding. other factors like a smaller Tungsten suitable and a narrower Gas shield and getting the right Volts and AMPs and that said the type of metal all take a factor on achieving a perfect weld. Just to say Stainless steel is very easy Well if your doing small items, I would recommend a machine like this DX-808 80A Pulse Spot Welding Handheld Pulse Spot Welding Machine As it has very low Amps suitable for small stuff. But if you already have a Tig welder then play around with it from the suggestions/Advice mentioned and let us know how you get on, Oh i would say practice on thinner metal than what you intend to use, as harder it is the better you will become. and easier .
Google cold welding. It is actually very interesting but not what I would call welding. More like fusion welding. Two surfaces which are clinically clean are brought together under pressure and the atoms of each surface can't distinguish between the two so cross over and form a homogenus bond and become one.
It's an editing trick, it's just regular tig welding but they edit the cooling and make it look instant. No doubt to get views, engagement, and comments. It worked!
Mig or stick welding is nice on bigger things but this is neatness without much cleaning afterwards also thin materials burns away quickly with mig & stick
@@shotgunsam23 thats pluse tig he has a pluse setting on his machine u arnt welding aluminum to steel i r melting it over its not good for and pressure like pipe nothing special at all
There is nothing cold about this. The welded area is so small that the surrounding metal absorbs the heat from the plasma arc so you can touch it almost immediately after welding. That arc temperature is anything but cold.
I have tig welder with spot welding function and there's nothing cold about tig spot welding, maybe joints can be "cold welded" which is imprfection or lack of fusion in weld.
You are awesome. For all of you saying this is not cold, it is cool enough to keep on a table after it is welded, that's pretty cold. For all of you saying it is not structurally sound, wtf, she's just showing tack welding, and melting small parts together, filling tiny holes in cans and tanks. She's not working on a skyscraper or bridge you daft pricks.
Eso se llama suelda tig y suelda mig. En un distribuidor grande de soldadores puedes encontrar. Esto no es suelda fría por cierto, aunque el título así lo dice.
@@fepto118 this is technically TIG spot welding. Most of the welders I have used has this function. You can set it to dump say 220 amps in 1/10th of a second.
You could say some adhesives cold weld since they dissolve the material being bonded as opposed to glues which is more like soldering or brazing that "sticks" to the surface.
@@blackz06 think of this a bit as tack welding. If you've ever tacked something together you have noticed that in order to get things nice and secure you need to apply more than a pulse, and more often than not a tiny bit of material. What that extra period of time when tacking does is increase the material temp and increase the penetration, giving you a much better fusion. When you use this type of spot welding, you must use much higher current because of the little weld time that does not create a good fusion. With thin plate, for example, you can use regular tig settings at very low amps to tack/weld, being the most important thing adjusting your speed to your amps. Your aim everytime is to move as fast as possible, so you get your amps higher in order to do that. So jacking up your amps and moving faster will make it cook your part a lot harder. Low amps cook it bad because you can't move. With this thing, you'd have to use ridiculous settings to get a decent weld. Other than those cases, you might be able to use this function in extremely thin material which you might not be able to weld even at super low amps Also, if you have pulse settings, it's always better to use that (if the material isn't too thin anyway) than the "cold" function just because it doesn't do 0-100%-0, it's a lot smoother and still controls heat well
@@jasonwood5988 what? Most definitely that is not the case. You can use copper for brazing joints, but that is NOT WELDING. In order to weld copper to steel you need a special allow called CuNiFer that can indeed fuse with both materials.
This isn't 'cold welding', it is TIG 'fusion' welding (without filler rod in most examples).

@@Bob_Adkins more like the paper glue stick of the welder world. Or maybe the chewing gum...

Fusion, TIG Fusion welding is got to be one of the cleanest welds there is using the natural ingredients of the part. I learned how to Fusion weld with a torch back when I was in school as a kid funny though my teacher couldn't break the weld that I made he could only break the actual Steel. Thank you so much for sharing
Nothing about this is cold welding, it is tig welding where she just taps pedals once fast for quick pulse of electricity. Any metals can be welded, the properties turn liquid and mix together to form a new alloy. The trick is will it be strong or just appear a copper pipe is welded to steel. She has to put the 2 inside each other because end to end they would not stay connected. This is click bait to get attention and nothing more.
Agreed. Cold welding is where pressure causes fusion. As in the occurrence of overtightening certain types of threaded matarials....
Titanium being one of them.
TIG fusion welding is very useful for taking the place of glue, tiny spot welds, and for tacking/positioning. It's great for attaching thin parts where cosmetics are critical, but strength is not. I have never heard a "cold welder" claim their welds are structural, so there's nothing to argue.
This is awesome it's very nice art. I'm going to try this. Looks like fun.
This is not cold welding. This is tig welding on a spot weld setting. Cold welding involves pushing metal together at great pressures and them welding together by the molecules exchanging atoms at the surface of the metal. An example of this is that you leave a block of lead on a block of gold after a week they will weld themselves together just from gravity. This can happen with gold and lead because they are similar but other processes need pressure to do so.
Sounds like you speaking more of explosion welding.
It cannot be done! Even rocks in the Earth need heat to form different elements. It's a law of Thermodynamics of transferring any type of energy.
@@rduse9197 although this is not cold welding, cold welding is real. It is something that happens with pure(unoxidized) metals in a near perfect vacuum. They will naturally bond together. the astronauts who work on the space station have to have ceramic coated tools because of this problem.
@Timothy Wess
Ceramic tools in space. I was unaware of this, but the only thing I can think of is there is no shielding from the Sun as a radiation source. So through electromagnetic radioactive force, metal tools either magnetic or highly conductive can but slightly ionized causing the molecular bond to be in a semi-solid state....but why wouldn't the laws of thermodynamics take place? The tool should not only weld but also heat up to an extent... unless the laws of physics are different in space's vacuum.
You may be able to glue an object to another like solder, but as to fuse into the other metal and realign it's crystalline structure, I don't think that is possible and I would definitely not trust its strength or integrity.
no. cold welding is when you have a super clean surface that attaches to another metal surface without it being warmed up in any way, its possible to do with gold, explosive joining sort of utilizes "cold welding" but with a lot more pressure on it
Clever editing 😉
Necesito una profesora así...😉👏👏👏
I just watched a video on this… cool idea and I believe it works by spiking the voltage however it gives you no penetration in your welds
Right. It's not welding.
This looks like a slow pulsed TIG welding process. So beautiful thank you for the video !
It is a mis use of a tig torch.
SE VEE MARAVILLOSA LA SOLDADURA...
You picked some nice music for this!
It's actually Pulse Welding. You send a high current short duration pulse.
For pipe to get a strong weld you need to be able to pulse weld the inside seam as well.
And now we know why plumbers steal wives.
This is capacitive discharge..
For a pipe to weld with strength you need to do a root run. As you pump in the filler you'll notice a small hole that looks like a key hole. As you pump in the filler it developes a type of run which is also purged internally at the same time as the filler is applied from the top through the Keyhole effect. Once the weld is joined probably 2 CAP RUNS are done over the root run deposit. They are a little hotter allowing the cap runs to help suck up the lower root run into the CAP RUNS...this is where the strength of the weld happens. Some seem to favour
" Walking the Cup" creating a one seam that is just a little wider than the 2 CAP RUNS.
Walking the Cup can make the weld look better visually. I favour being effectively, leaving a 1st Class result. Per industry Standard.
There is no inside welding to smooth things out.
Unless it's a robot sled doing Pipe lines.
I've seen root run leave Haemaroid like hangings inside food grade tube joins. All has to be cut out...&...not from the inside I assure you.
Buenas tardes,

This welder is a absolute piece of crap. None of those welds are strong enough to hold anything worth welding. You can break it apart with your hand in order for a will to be strong, it must fully penetrate the metal. This has zero penetration. It's garbage do not waste your money

Как быть с зоной термического влияния, где концентрируется напряжение возникшее от кратковременного разогрева и быстрого охлаждения сварного шва и основного металла?

That is awesome 👌
She gives a clear explanation of this process domo arigato.
It's so nice to see even its not cold welding or whatever you call it (pulse welding) ;) It's like magic for "the one who don't know" :)
The real problem is it isn't anything. These are just tacks but every single tack is completely edited to look like an instant shot but that's not how it's actually done.
So it's wrong and misleading and also useless
2:05 gives a good example of the weld strength lol
👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻 Excellent. 😊
That is the coolest thing I've seen today
This would be good for fine or a small weld of tiny objects. Where can i get one.
Just buy a tig welder and pulse that.
Deadass
@@mrgreenswelding2853 thats all this is is a mini tig. But i was talking very small welds like in very tiny spaces.
What's the weld penetration depth?
Can this be used in construction or not?
Because these welds look very superficial, not deep enough to be strong.
This can't really be used for anything.
I want to know more about this, Ms Weld!
Very nice
Imagine buying a car with this kind of welding, it will split in half just after goin around the first corner hahaha 😆😆😆
yea it's BS
@@UkanlosSmasher Would it be bullshit to weld sculptures that require no strength like this? Would you recommend gluing over it?
@@valkenburgert no for some specific uses this can indeed be useful, artistical use like you said, or for fill up welding on parts where you want to avoid as much heat as possible.
But for real welding this is not good.
@@UkanlosSmasher For real welding obviously not. But would that render my applications “bullshit”?
Joined a welding forum too so not talking purely RUclips but definitely feel the welder community is not the easiest to access. I think experienced welders forget how mental welding is to the general audience. Loads of people find changing a lightbulb quite scary 😂
I will start to weld by lack of good (practical affordable) alternatives. But trust me I’ve looked.
If someone looks at cold welding they are most likely scared of welding. Welcome them, be nice. Laughing and calling it bullshit doesn’t help.
It took me forever to figure out you need gas and an expensive machine for “tack welding” like this.
Anyway, totally unfair to call you out, could have been most people here, so please consider this message to be directed @all.
Just trying to stand up for the noobs like me that will take interest in this nice, safe-looking, easy way of welding 🙃
@@UkanlosSmasher I got that in the end 👍
My point is that loads of people watching this are trying to avoid real welding. Most likely since they are intimidated by it. I still am 😊
They need reassurance and explanation. Being ridiculed doesn’t help if you’re new to something and people believing this movie will be new to welding. It’s the target audience…
So it’s like single pulse high amp tig welding.
Is it? What about the heat tig welding generates.
@@jerrylvega8446 this isn’t literally cold, it means that it doesn’t dump a whole lot of heat into the entire part. If you have a tig machine this function would be called Tig spot.
@@jerrylvega8446 As you can see from the video, it's not cold, and a poor weld.
@@hetrodoxly1203 I don’t know. It seems like a good weld. But as someone pointed out it is superficial. If you could do it from both sides seems like it would be good on parts not too thick. I liked the welding track. At least it’s not chicken shit. Seems ok for lighter stuff actually which is desirable.
@@whereswaldo5740 As a retired welder in all it's forms i can say with all certainty this would fail all known tests, these results can be achieved with a standard TIG set.
Very cool.
Is that a capacitor? What are the characteristics of the rig, schematic? It's really cool! Thank you!
Call it what you like, but metals (mild steel, stainless steel, aluminum, brass) don't melt when they are cold. I've been a welder for 55 years and I've seen almost every kind of welding, in all cases the metals have to be melted. Lead/tin solders melt at the lowest temperatures, a couple of hundred degrees, still hot enough to destroy your skin if it were exposed to that temperature.
Totally not what we call Cold Welding in the US..... But it was still very well done and im glad to have seen it.
Much appreciated :)
Love these tack welds
What do you use to sharpen your tungsten?
Yea I noticed the tungsten tip looked weird. I put mine in a drill and use a carbide grinding wheel. Hers looks shaved almost like a pencil sharpened with a razor.
This is cool.
This is great for holding parts together until you actually weld / braze the parts.
Isn't this real welding?
@@wagnerjunior6524 basically no. This doesn't penetrate the base metal much at all so it will be a very weak weld.
@@duncanweir8773 Seems like it would be good for lighter stuff like expansion chambers on dirt bikes or replacing sheet metal on rusted out auto body. Or things I would want to do. Not actual welding but seems useful.
If you notice all their joints are perfect, if you have a gap it would be very difficult
Good point
As a pro Welder for over 30 years I can say this is a long delay pulse welding and is a fun way of welding for cosmetic looks for the home hobbyist.
Nice for you to take the time and demonstrate .
I'm sure their are going to be many people influenced by this video.
Just to say as mentioned in other comments this only gives about 30% to %40 of strength depending on materials used and has a lot of weld pool shrinkage and so makes it no good for parts that need to be strong.
Example Steam pipes, as in no time there would be so many leaks.
as a person who has been around a lot of welding through work , whats the difference between this and a TIG? this looks a tig welder to me (but of course just because it looks like that to me doesnt mean it is)
@@antaLord It is still Tig welding but without forward heating.
Well the Chinese are calling it Cold welding
In welding terms it is a failed weld.
But cosmetically looks and performs ok on decorative stuff as shown here and these items don't require structural strength and is just to look good.
Meaning this Cold welding saying is a spot weld feature on the Chinese welders that are being marketed as if its a new idea of welding, in fact its been around since TiG machines were invented,
It was a way i started to weld a long time ago on very thin metal. Almost a tin foil for British aero Space
as forward heat would burn it to nothing.
So If you have a TiG welder with a Pulse feature, your more likely are able to change the frequency( Pulse duration ) to a very slow rate and so you can do the same. just turn up your AMP's to around 100-120 for 1mm to 2mm metal. you may have to tweak the up and down cycle rate to, also you don't have to use full Argon, you can also use just Co2 or a Argon mix as their is no burning for oxidization
@@spudnickuk ok, yeah i thought this looked alot like a tig, thanks for explaining!
@@spudnickuk so the slower the pulse, the thinner the material you can weld without melting it entirely?
I'm thinking about learning to weld watch cases/parts using TIG as a more affordable alternative to laser
@@kevintanumihardja3881 It is not just about slowing the frequency to achieve thin metal welding.
other factors like a smaller Tungsten suitable and a narrower Gas shield and getting the right Volts and AMPs
and that said the type of metal all take a factor on achieving a perfect weld.
Just to say Stainless steel is very easy
Well if your doing small items, I would recommend a machine like this
DX-808 80A Pulse Spot Welding Handheld Pulse Spot Welding Machine
As it has very low Amps suitable for small stuff.
But if you already have a Tig welder then play around with it from the suggestions/Advice mentioned and let us know how you get on,
Oh i would say practice on thinner metal than what you intend to use,
as harder it is the better you will become.
and easier .
This actually pretty interesting.
Would this method work for joining 2mm galvanised steel wire mesh together?
Trying to find out about actual cold welding and I get some slag with a TIG
Lmao
Google cold welding. It is actually very interesting but not what I would call welding. More like fusion welding. Two surfaces which are clinically clean are brought together under pressure and the atoms of each surface can't distinguish between the two so cross over and form a homogenus bond and become one.
This would be interesting to see in a high speed camera how the molten metal is forming and cooling
It's an editing trick, it's just regular tig welding but they edit the cooling and make it look instant. No doubt to get views, engagement, and comments. It worked!
SALUDOS DESDE PANAMÁ Y EXCELENTE TRABAJO😀🇵🇦😀🇵🇦🇵🇦😀🇵🇦👍🇵🇦🇵🇦
So very cool
Im no welder but this looks cool, thats a very large amount of energy concentrated in a small area
Mig or stick welding is nice on bigger things but this is neatness without much cleaning afterwards also thin materials burns away quickly with mig & stick
It’s basically single pulse high amp tig.
@@griffin2zion if you had a Tig welder this function is called TIG Spot.

@@floorify1398 okey

That's awesome
There is nothing cold about this. The welded area is so small that the surrounding metal absorbs the heat from the plasma arc so you can touch it almost immediately after welding. That arc temperature is anything but cold.
2:08 That should hold up... Isn't that how they weld pipelines? HAHAHAHAHA
It was already cracked 😂 this is great
Probably broke it apart intentionally for repeat demonstrations of the welding process.

How much does it cost a cold welding machine. I hope you can help me. Nice video.
Reputable ones (SANWA/NOVAPAX) cost about 6000-10000 Euros.
It's tig with a timer.
And we wonder why chinesium parts fail.
What amazing magical machine?
That works good
Poor penetration and porosity left behind on most of the examples.
How much does it cost a cold welding machine. Thanks
Seems very good for art project welding.
I have tig welder with spot welding function and there's nothing cold about tig spot welding, maybe joints can be "cold welded" which is imprfection or lack of fusion in weld.
Extremely weak welds. The welds do not penetrate the pipes only the surface.
😂😂😂
You are awesome. For all of you saying this is not cold, it is cool enough to keep on a table after it is welded, that's pretty cold. For all of you saying it is not structurally sound, wtf, she's just showing tack welding, and melting small parts together, filling tiny holes in cans and tanks. She's not working on a skyscraper or bridge you daft pricks.
Those welds wouldn’t hold shit, there’s 0 penetration.

I don't recommend using the phrase "cold wielding" as it's inaccurate and bound to attract less views and make people mad
No such thing as "cold" welding.
It's nothing but a pulse tig welder set to only arc up for a short amount of time.
Thank you for watching and wish you a happy life😉
You could say some adhesives cold weld since they dissolve the material being bonded as opposed to glues which is more like soldering or brazing that "sticks" to the surface.
Another too good to be true for guys that want instant welds where not much work is intended.
Always nice to see a vid from people that have no clue what they are doing
This is just a tig welder with a switch, the welds are not cold, they're weak. Also, you cant weld copper to steel, wtf mate
Would it be good for thin stuff?
@@blackz06 think of this a bit as tack welding. If you've ever tacked something together you have noticed that in order to get things nice and secure you need to apply more than a pulse, and more often than not a tiny bit of material. What that extra period of time when tacking does is increase the material temp and increase the penetration, giving you a much better fusion. When you use this type of spot welding, you must use much higher current because of the little weld time that does not create a good fusion. With thin plate, for example, you can use regular tig settings at very low amps to tack/weld, being the most important thing adjusting your speed to your amps. Your aim everytime is to move as fast as possible, so you get your amps higher in order to do that. So jacking up your amps and moving faster will make it cook your part a lot harder. Low amps cook it bad because you can't move. With this thing, you'd have to use ridiculous settings to get a decent weld. Other than those cases, you might be able to use this function in extremely thin material which you might not be able to weld even at super low amps
Also, if you have pulse settings, it's always better to use that (if the material isn't too thin anyway) than the "cold" function just because it doesn't do 0-100%-0, it's a lot smoother and still controls heat well
yes u can mig weld copper to steel , just have to heat up the copper have a nice day mate
@@jasonwood5988 what? Most definitely that is not the case. You can use copper for brazing joints, but that is NOT WELDING. In order to weld copper to steel you need a special allow called CuNiFer that can indeed fuse with both materials.
@@jasonwood5988 did they fuse together or the copper make a seal grip to steel so it looks like welded?
