I like how, when I have questions.. I type it into UA-cam, and we get smart dudes like this detailing the answer.
You are dumb we know
@@joemarooni4580 and you're not?
Stumbled on another one of your videos again trying to learn something else. RIP buddy, thanks for helping us!
if you are welding thin gauge copper argon works just fine. the tuff part is that the puddle wants to get too big and fall in....you have to move fast, or have a backing plate that absorbs heat and support weld.....I find keeping the rod in the puddle using it as a coolant pushing it in extra fast when you got the puddle to large and hot......also using rod to shield the edge from melting too soon. I use sheet metal screws as clamps and weld the holes later when screws removed. got to keep sheets together tight in overlap to weld thin gauge, protect edge from melting by shielding it with rod....put heat to bottom layer, then let the puddle swallow the edge in the bead as you move along.
I have literally performed thousands of welds on copper using pure helium as cover gas with a gas lense and other than the heat absorbing rate issue never found it any more difficult than aluminum or stainless. Argon was a different animal and I was rarely able to make as nice looking or clean welds as I could with helium.
Thanks for lesson! I am a beginner in welding and this learned to me how to weld a moonshine device. Thank you twice!
Dude has some title, world renowned tig expert
I welded some copper bars together at my job and I used argon and it worked pretty good. ( ??? )
They were rather small. 1/8 x 1/2"
We don't have any straight helium gas, but sometimes they have helium/ argon mix. I'll have to try it again sometimes and use the mix.
Initially I was like wow someone's full of themselves with a nickname like that.
But by the end of the video I fully, fully understood why that name was earned. Very impressive sir.
Good video! We were welding some 316 s.s. heat exchangers many decades ago and we ran out of argon. Since it was the weekend and we were on the clock on o.t. and all of the welding supply stores were closed, we grabbed a chromatograph grade helium bottle from the tech. service department's bottle rack (don't do this, those bottles , back then, cost about $400.00 each for refill!!) and hooked it up. Upon t.i.g. welding again w/the helium I had to turn the amperage down from 92 amps to about 55 amps as it was running too hot/fast to keep the stainless in the "cool zone" and not "sugar". I didn't know about the heat transfer/active properties of that particular inert gas back then, thanks for explaining the 1.7/1.0 thing to us! Keep up the excellent work and just ignore the trolls! : )' p.s. I have often wondered how the other inert gases (xenon, neon, etc.) would work for t.i.g., with the obvious exception of RADON !!!
I have also used an Argon/Hydrogen mix for this purpose.
A Coppersmith friend recommended this mix and they were using it on Brewery/Distillery stills up to 6mm thick.
I love this content! Wanna know how to really heat those metals that conduct heat really well? Hit 'em 70% harder! I don't think the topic of ionization energy of our shielding gas comes up often enough. Not trying to tell you how to do a job you already rock at, but maybe show the people DC (He shielded) aluminum vs AC TIGniss. Thank you for the content, Cheers!
What a difference helium made. I think the other channels struggle and have to go very slow in comparison to what I just seen you do . 👍
You just saved me a lot of headaches on my first attempt when I go to try my first copper to copper
This is a great start for an idea I am working on... Welding cymbals. My video project is on cymbal refurbishment and the alloy involved is mostly bell bronze (80% copper, 20% tin with a trace amount of silver). I also have some brass too.
I am looking at welding as an possible option for repairing the cymbals but their are considerable challenges involved with the alloy's properties.
I would love to see an episode on this specific application.
After watching his series of welding cymbals it just came to my mind why he didn't use this method to weld them. He only used that torch to melt filler material. I don't think that method can create a good solid weld like the method on this video presents. I would like to see the resulting sound of a cymbal welded like this after some lathing and polishing.
Cymbals are very strange metal indeed.
Drummer in my brother's band had good top name cymbals and doing a lot of playing in cold garage made them crack all up.
Good luck welding them
Thank u! I can say I learned something to day about helium! Thanks again for the video
I'd like to see how to do this with argon. I don't really want to buy another cylinder just for an occasional copper project.
The argon taking quite a bit of the heat away with it so unless its quite thin plates or such it just won't go through. Helium does not take the heat away and thus you can get quite deep with that, its much more expensive though.
You can do it with argon, just takes longer to heat the copper up until it will pool. Helium is more efficient for production work if you have to make 1000 pieces of something but if you’re just doin a one off it’s not economically viable to buy a tank of helium you aren’t going to use up. Argon will get it done, just 4x slower
Very cool video. I honestly thought copper could only be soldered!
Soldered, silver-soldered, brazed and welded!
always love when he says "let me get my gear on"
I learned a few things in this video. I will review it again to see if I miss anything. I will experiment using pulse. I have a project that I need to get back to. Thank you and as always good job.
I weld copper and another good tip is use stainless brushes to clean and run extra high purity helium for cleaner welds
So, you're getting your filler rod from Romex, residential wiring? Very neat.
I wish I could afford a Tig machine, I learned and got certified in collage, but haven't done any work in a million years, I am now making jewelry, and have been using the stove and a torch to fuse the ends, but it's eating more gas than I like.
No visible warping, porosity, or undercut. Fine video.
Do i need to use hilium gas right? mr tig instead of Argon? what type of tungsten do we need to use for tigweld copper to copper?
Can you do a video on how to weld copper on copper with a mig welding set-up or tecniques explaining step by step on how to do it by using wire copper feed
Doubt you can get copper might wire
Good stuff. Thanks for sharing.
How many amps DC? Great video. Thanks
I would have loved to seen footage of a copper fillet.
Hey can you make a video tig welding very thick copper ???
I would like to know how thick a piece of copper I can weld with a 250A everlast welder.
Probably not! Unless he does some heavy preheat.
What kind of tungsten did you use? and do you have to use a air cooled torch for copper?
fast and smart. tnx, Mr. Tig
Gorgeous weld.
Thanks, Mr. Tig!
That's such a bad ass face plate.
awesome very helpful... I'm an artist.... these videos are helpful, with my understanding how to effectively combine different metals/alloys together in one art piece.. thank you
Do ou think is it possible to TIG weld a plate of aluminum and copper? Thanks from Brazil.
how did the old-timers weld copper? i have seen old steam-driven machines with pended copper joints as well as old food grade applications. I was in an old beer brewery and one of their kettles was welded in two half globes
how the heck could they do this before tig??
weld done
underrated post
would this weld hold up to heating , like if it was used in a still, and still be air tight
Weldign copper looks like fun. I need to try that with my powertig. Can I weld copper to steel?
100% helium?, I always wondered what filler metal to use, Romex solid copper electric cable, thank you, Great Video
Maybe you could preheat it with a blow torch then use your regular argon.
I want to try this, I have a miller inverter machine, honestly can't remember the model number, bit it will work on 120v bit is much happier on 210
Do you need a water cooled torch at 200 amps plus helium? I know I'm at my limit with an air cooled torch at 200 amps with argon.
I guess it depends on the model of the torch. Some have a higher amp rating but they get pretty big. I'm saving up for an everlast mig welder that can tig weld. If I were welding that high with helium I would go for a water cooled torch because it would much smaller than an air cooled one with the same rating.
If you’re welding for just ten seconds, or so, then no.
How do you harden the metal?
Is it annealed after tig welding?
I need to weld three soft copper 1/4 OD refrigerant tube together for the purpose that they will conduct heat between each tube. It is not important that the welds are perfect because they don't need to hold refrigerant just the copper has to conduct heat. I am welding about 1000 feet so I am not sure which is the best method for speed. I think even the plumber's solder would work but this is a lot of soldering. Any suggestions?
Nice video (as always)! Would working in a purge chamber (like I do for Titanium) make longer runs and more complex geometry easier to work with? I've welded with Argon in the past and found it to be challenging, but not entirely impossible.
The problem is thermal conductivity. You have to have a certain amount of intensity (watts/square cm) to GET a puddle, otherwise you just get the whole thing hot. My Everlast machine would not start in Helium, it also warns about this in the Everlast manual. I found that with say 20% Helium the action is different and I can get a puddle on a copper plate.
You awnser my cuestion thank you mr tig
Why did we not get to see the final product?
hi Mr TIG, thanks for uploading this, you answered a long lingering question on my mind about welding copper.
the machine i have is a lincoln invertec V130S, it goes to 130 amps. up to what thickness of copper do you recommend to weld with small of a machine?
I tried to tig weld copper once, it went like this:
Start arc. Sit there for 5 minutes waiting for puddle to form. Cut arc, give it 50 amps
Start arc, sit there for 5 minutes and wait for puddle to form. Cut arc, give it 50 amps
Start arc, sit there for 5 minutes, the whole peice flash melts. Give up
Quarter inch thick 4x8 inch plate, ended on about 250 amps.
Great instructional!
That was cool! I'm such a newbie to this, I'm new to power tools, let along welding! :) Just found your channel. I'm hoping to weld some different sized copper pipes together using a joiner - 1/2" and 3/4". Any advice for that? Thanks Mr Tig!
Are there any special precautions to take when welding food grade copper?
All copper has a tendency to release poisonous gasses. So a fresh air system is a must on large stuff
Maybe purge the inside of the pipe? Do people DO this? I don't see why not, but haven't heard of it.
I tried to braze copper to copper using silicon bronze filler rod, but the filler would not stick to the copper, it would always fall off. Any idea why?
What does your reference to CFH refer to? Im guessing its probably linked to pressure but its useful to know! Thanks!
Cubic feet per hour
Can this be used for liquor steel
will pure argon work for 1/64" copper sheet? I have an application where id like to use copper. My tig welder can do 160A to a #17 torch.
Liquor
Same here
Did you buy a small tank of helium
I used pure argon up to 1/8 inch copper using my Maxstar 160 at 150 amps....no problem.
So this does work with pure argon ??
Where do I get copper filler ?
@@TiginwithNic just strip electric house wire Gauge 14, 12, 10...depending what you need. to stiffen/straighten it, put oend of a 3foot length in a vice, grab the other end in a vicegrips and yank real hard several times...this makes stiff and straight easier to handle
@bill hopen thanks !!
Should I clean it up to be shiny?
Superb skills!!
I've been around a LOT of welders/pipe fitters. I've even got a Miller syncrowave 2000 with a water cooled cricket. I've had welders write there name on a aluminum beer can,BUT I never ever found anyone who would even ATTEMPT copper. I've seen my friend do root filler cap welds on pipe and, it got to be a joke. He'd ask me:
" You want nickels,dimes and, quarters?"
I'd reply:
" Dumb ass, you know it's dimes,nickels ,THEN quarters!"
You have to be a welder to understand.
YOU ARE A WELDER
Boa noite, sou do Brasil, estou escrito no seu canal, qual material de adição que você usou? Obrigado.
Hello, please help me. I want to weld 1mm brass and copper sheets. Today I have tryied to weld with silicon bronze rods, but it wont stick. When I set amps to 120, brass sheet was with burning holes. Please share your experience. It's very important to me. Thank you very much!
How much is your welder/inverter worth?
Was the machine on DC - ?
andychrist77 Yes, he states it at 3:03 mins.
How is the best way to put together 2 peaces of 8 gage copper wire ?
The proper crimp and strain relief
Can I tig weld small copper parts with a Cigweld 250i?
Thanks Wyatt! Another great and useful (oh, and timely) video! I'm about to take on a big copper project, but I'll be working with 28oz sheet metal - what would your thoughts be on welding sheet metal and since it's lighter gauge than your 1/8" demo and I have access to higher power machines, do you think it could be done with argon?
How did it turn out?
any tip for welding copper c110 specifically, it must be structurally sound, 1/8" sheet
Why does the amperage have to be so high when welding copper as opposed to steel even though steel has a higher melting temp than copper?
The copper acts as a giant heatsink. You need those amps to create a puddle otherwise all your doing is getting your work piece hot.
thank you Mr. TiG!!!
+jdh023 yeah, I agree...if I remember correctly my dad and I were debating the ability to weld copper. he said it wasn't doable. lol. TiG was 100% for my inquiry. . also, thanks for being a good instructor. welding properly it's crazy difficult if you don't know what your doing.
+jdh023 just age and boasting. lol. I've done minor welds in all fields as an assistant on construction jobs building a baseball park. I wouldn't by far say I'm any good at welding lmao. though, a copper tube was fluxed not to long ago and I mentioned it could be welded and he was saying only a torch and flux....needless to continue I just went to youtube lol.
+jdh023 jet engine blade backups...to weld for something so serious. that's got to be a good one.
+jdh023 I see, the memory is personal, so I do understand the difficult to relate. as for the welding, thank you for the knowledge! it's most appreciated.
What if you have a 300 amp.welder?
sir copper welding haw to gas use
And haw to macin ac dc
What color tungsten?
Could you weld a copper pipe together instead of sodering it for more strength ? For sculpture not plumbing lol
Would you mind a shot of the back side?
Mr Rig if you use heat sink material of copper like hot dam would WELD easier?? RG
Heat sinking would make it WORSE, and maybe impossible. High thermal conductivity is the basic problem.
totally enlightened
i freaking love you man.
I bet that equipment isn't cheap. Can anyone give me a theoretical estimate how expensive it would be for me to do a couple very small pieces for a computer heatsink? I want to make a custom heatsink for a laptop since the one provided is not enough for the hardware I need to cool.
I could knock out a little job like that for 50 depending on difficulty
sir what's problem not use argon gass. sir plz give me aa lecture of gesses use in welding.
Bara Jee if you have enough power in your welder, you can use argon. But for what he did, you would need 300 amps.
can copper be somewhat welded without shielding gas?
Don't talk to Mister TIG like that! People used to weld copper with torches you know, but that's a different channel.
which type of filler wire can use in copper welding
Copper wire
Can you weld with hydrogen?
I was wondering: Could you wrap several layers of fiberglass, or welding fire-blanket around the copper pieces, to insulate them, so that they don't keep sucking away the heat?.... (just a thought).... and, perhaps support the pieces on a more insulative material, (fire brick, charcoal blocks, etc)?
guloguloguy the fact that copper takes the heat so fast away from the weld joint is the issue. Copper is very thermo conductive and this is why it's so hard to weld
guloguloguy no. Because that would shield it from external losses, which are minor. But the copper is so conductive that it will suck the heat away under the insulation.
What machine do you recommend for welding copper. I am Yartist and want to weld copper to remove any seam. You used an air cooled torch is that really enough?
Thank you
It all depends on what thickness of copper you will be welding. If you are doing short runs on thin copper you can get away with air cooled. Copper takes about 20 - 25% more amps to weld than steel if you continue to use Argon, so if you are doing any sort of thickness you should move to water cooled. There's a Mr. TIG package on Weld.com that is a good water cooled package for a good value: weld.com/index.php/shop-weld-com/shop-weldcom/mr-tig-kits/everlast-power-tig-250dx-water-cooled-package-detail
aerowave,
lol. or a dynasty 350
you could do a lincoln nascar square wave welder too.
always water cooled with copper
Helpful information for writing here! #Steampunk
I'd be curious to see the amount of penetration. Good video

ok can the exact thing be done by using an oxy/propane torch? in other words can i braze cooper using cooper wire ? also why are you calling this welding if the heat needed to melt cooper is at brazing temps? is it because you are melting the base metal along with the filler rod? what is the definition of brazing vs welding then if they say that brazing has to be above 840F and below the melting point of the base metal but what happens when the base metal is the same ,is it now considered a weld and no longer a braze?
Brazing has nothing to do with this! Oxy Propane can hardly weld anything, but can solder, silver-solder and braze a lot of things! If the base metal is melted, it's WELDING, no matter what the material! An example, BRASS can be welded or brazed, I've done this as a demo. Using the same torch! To weld you get a puddle, and might or might not use any filler. To BRAZE you heat the base metal but only the brazing rod melts. With care you can get the brazing material to flow like water over a piece of brass, which is CLEARLY not melted!
@@leonardpearlman4017 yep thanks
Thank you, Mr. Tig! I feel sorry for you - having to read all the stupid questions and dumb comments below must be excruciatingly painful. “...uuugh, can I weld super thick copper to very thin sheet of plastic? Uuugh... with my new power blablabla Tig?” Jesus!!!
Baby stuff try welding t4 2½ copper pipe using a pulse mig welder and a rosebud or aluminum bronze wire welding copper to steel alot of technique
Man you're so tough. You realise this is a tutorial on how to weld with copper and not whatever you said, right?
Yes I do realize that we use copper wire to weld copper to copper pipes we use deox mig wire by harris with 100 argon and preheat with rosebuds
Pretty much all he's doing is melting thin material together all I'm saying is the amount of heat that is used to heat thick wall pipes is high like 5 minutes of just preheating with a rosebud doing that in the middle of summer is a bitch we build copper panels that go in furnaces at steel Mills there's only a handful of places that do it in country
@Freud Madebetter I'm not a know it all but welding copper is something I do on a regular basis so it is something I am familiar with
@@chungus100 if you listen to the beginning of the video he is talking about silicon bronze which usually tends to crack especially in copper applications bronze is usually only best when welding steel to copper or will crack especially silicone but he didn't show that in the video but he was talking about it
Can I get away with this if its as thin as sheet metal for an art sculpture?
Helium is expensive!
ok so it's a little different, not so much easy, but just a few different characteristics. I was watching another video, seemed a little easier, but not so much.
Why is it everytime I subscribed to mr. TIG it gives me some other guy on wild.com can you explain that to me
Weld.com has several shows and people.
No hate for Mr. TIG, but I prefer to watch my man Bob Moffett(?)
Is it possible to build up a copper contact like on an older starter motor? Anybody know?
Dylan Dembrow brazing may be a better option
I would machine a new one instead. No guarantee that building it up wouldn’t result in porosity, and oxidation along multiple passes.
The only way it works is with helium huh? Pretty funny that Jesse James does it with argon all the time..
Tempting to run it off an engine drive to get enough amps for it.
mig can weld copper neikel
Is name really Tig?
