In this video: Jeff does a quick tig welding/brazing demo of 3/8" copper round stock. Welding with 14 gauge copper wire and brazing with 1/8" low fuming silicon bronze rod (flux removed). Its not the best video on this topic by far but we just wanted to get the concept out there for you to think about ;)

dude that was a very cool vid.....straight to the point, honest, accurate and helpful....thank you

You're absolutely right about using helium. Alushield - 27% Helium, balance Argon - is the shielding gas of choice. Much more stable arc for welding copper. Used this for all electric motor rewinds, DCEN with thoriated tungsten (red) for my career. Good comparison video. Thanks for taking the time to post. ✌

Nice ❤

Great video. I need to try brazing with my powertig welder.

@mattali3414 3 года назад

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?

@kaseychambers4788 6 лет назад

The problem might just be that when you weld one side it shrinks when cooling making the other gap slightly bigger on the opposite side. You could try tacking it down to keep it from distorting, or put some vice grips or a clamp on there to help prevent it from rolling open when that welded side shrinks.

I've never tried tig with copper but it's on my list. I've always been told to get de-oxidized copper filler. Do you know if it makes that much of a difference? Also curious what your parameters were. Doesn't sound like the buzz of AC so i'm assuming DCEN. How many amps? Great vid, just found your channel and sub'd. Blacksmithing was a big interest to me during welding school, and I plan on taking it up as a hobby eventually. Off to check out more of your vids!

@dougankrum3328 8 лет назад

...DCEN....right, and you'll need a good size welder...you have to get a lot of heat in there fast....de-oxidized copper...don't cheap out on the filler wire, or cracks can be a problem....

@drunkenmoose8063 8 лет назад

Thanks for the info. I have an everlast powertig 250EX, hopefully be enough. Thanks again!

@PinoyBlacksmith 7 лет назад

was that straight argon when you used the copper wire?

Boa noite sou do Brasil, estou escrito no seu canal, qual vareta de adição que você usou para soldar, obrigado.

Wouldn't a "brazed"lap joint be MUCH stronger, if it were done between two relatively flat, and well mated surfaces (with lots of intimate contact surface area= instead of using round bars, use SQUARE/rectangular bars)?!... Great demo!!! Thanks! [&...Best wishes for your family/ and business, and a speedy recovery to your Father-in-Law!!!]

I plan on buying a Audew Welding helmet as my first helmet any tips?

@jeffreysanto 9 лет назад

+Caleb Couch Just make sure wherever you buy it from has the replacement lenses in stock, some companies do not use standard sizes and they can be a real pain to replace.

@jaydendavis7596 7 лет назад

I really like your work. I'm saving up for a everlast mig welder but now I'm thinking I will get one that can tig weld too.

@jasongill828 8 лет назад

LOL ALL THAT SMOKE.

@jasongill828 8 лет назад

AND USE SHARP LANTHANATED TUNGSTEN.

@mrod4864 7 лет назад

What is the point of recording this if you aren't actually filming the weld?

@jeffreysanto 7 лет назад

Point is there are people who so not know your can do this with TIG. That is the point. whats the point of having your own youtube channel if you don't upload your own content?

@jasongill828 8 лет назад

TRY HARRIS 15 BRAZE.. DONT USE BRONZE.

@craigrmeyer 5 лет назад

Can you comment on why everyone says to use SILICON bronze for TIG brazing? Everyone says to NOT use the brazing rod that one uses with a gas torch, but I still don't understand why. Do you?

@leonardpearlman4017 7 лет назад

Why not use Cu-Phos? I mean, there's rod just for this! People have been welding copper for a long time, there's literature about it. If it's a cosmetic application you can do anything of course.

@jeffreysanto 7 лет назад

You could use copper phosphorus brazing rod for this application, for me there were 2 reasons that I did it this way. The first is that this job needed to be done quickly. I do not normally stock this rod and the only smallest package of rod at my supplier was about $40 bucks and I could not wait for a cheaper online source to get it to me. If I bought it the remainder of those rods would have sat in my shop for a 100 years... and I only about 45 inches of rod of that. The second reason is that I never tig welded with it and didn't have a lot of extra material to practice on, I've brazed with it using oxy acetylene a long time ago but no longer have the oxy acetylene rig. I switched it over to oxy propylene a few years ago, its wonderful for cutting and heating but oxy propylene won't braze or gas weld well at all. If fact I think I remember hearing that brazing and gas welding is not recommended with it.

@melgross 6 лет назад

Propylene smells terrible.

@leonardpearlman4017 6 лет назад

(months later) The copper weld actually looks well, and is clearly welded! I'm not complaining here, it's an interesting area. Low fuming bronze seems to still have lots of fumes, I can see why people use silicon bronze... it looks like there is a lot of zinc fume when you're TIG brazing there. The flux normally helps to keep that down, and also an oxidizing condition of the torch if you're using a torch. It looks like you got something good at the end!

@alekseygrun2315 4 года назад

A lot of talking ... and low skill level. I did not realize what do you want to show - technology or skills? It is not necessarily to make video for video...

@jeffreysanto 4 года назад

Says the guy with 2 subscribers and no videos posted. It takes no technology or skill to be an ahole, but at least you give an effective demonstration in showing how to be one... hats off to you buddy. video has over 30k views and your the only one to say anything negative... Says a lot more about you than about the video.
