A satisfying repair on a unique piece of custom furniture. Learn to weld in my $39 online courses: courses.timwel... HTP Welders: HTP Welder: usaweld.com?ref=timwelds
I really like these repairs, there's always something to learn as a novice and also in some ways, these are the projects that most of us weekend welders work on.
@TheGodfather101 You're goddmaned right It works great! I don't make a great effort to be wrong about things. Electrical wiring, unlike say copper plumbing pipe, is very pure copper, so it doesn't have a lot of impurities, and it flows even smoother than mild steel, but you have the downside of the base metal Being a really good heat sink like aluminum. Still one of my favorite things to weld
@Rossco139 Never tried ac. You can use both argon or helium or a mix of argon and helium. If you use helium or a mix of the two , you won't need as much amperage. I'll weld up to 1/8 copper with straight argon no problem but for thicker larger pieces I'll add some helium
@@autodidacticartisan I can second this. I had to weld some 1/4" copper plates to ~ 1/2" copper bolts for a job. I welded it at 280 amps after pre heat with a rose bud and a mixture of Helium and Argon welded with DC using thoriated tungsten. It was a difficult job but I got it done and the customer was blown away with the quality of how the project turned out.
I love repair videos. That is what I do the most of (DYI'er). I learn a lot by watching how others attach a repair job. I now do repairs that I never thought were possible.
Great video! Teaching someone the welding skills is great and does need to be covered. Showing folks what they can accomplish once that skill set has been learned whets the appetite for learning even more! Keep up the great work.
That was neat to see how you fixed an everyday object like a coffee table. I never have tig brazed, so that was cool to see a good use of silicone bronze. I might have to use it for some similar repairs around the house.
I have a MIG machine but only run flux core wire for now…can’t afford a gas bottle setup. I’ve always been intrigued by brazing, and would like to see you do some vids on Oxy-acetylene brazing. I might be able to afford an Harbor Freight kit.
Thanks for the suggestion! I was running 3/32” (2.4mm) silicon bronze at a machine setting of 200 amps. I’ll include more of those details in the next one.
Great repair. I've tig brazed with silicon bronze; but if I'm looking for more strength, I prefer aluminum bronze (using AC). Unless you plan on dancing on it😂😂.... your silbro repair will last & is much stronger than the original build.
Don't want to sound churlish (as the TIG welding skill was excellent), but I'd opt for a 2% or 5%Ag CuP Brazing alloy with oxy/propane (and maybe gasflux if appearance is important). Much faster and probably less heat input.
Enjoyed seeing how you can use the tig welder to braze. Given a choice, would it have been easier to braze with say an oxy/acetylene torch? I was thinking the tig-to-workpiece arc would melt the copper, but with a torch you can keep the temperatures below the melting point of the copper base metal. Or does it not really melt the copper done the way you did?
Thanks! I think TIG brazing is easier than oxy-fuel. You can melt the copper with a TIG torch, but if you keep the travel speed high enough for the amperage, it doesn’t melt. The hardest part is getting the first dab of filler on.
To my knowledge, you'd need to silver braze the copper together. Getting paste flux off a joint attached to a table like that would not be very fun. I bet it would also be very hard to keep enough heat localized on copper tubing that large
@@ResonantElecDesign Using a CuP or AG CuP brazing alloy and using oxy/propane or acetylene doesn't require any flux on copper to copper joints. It does take some practice, but it is possible to achieve really neat joints.
Thanks! I’ve never thought about using torch brazing rods with TIG, so I’m taking a bit of an informed guess here. There are several types of brazing rod for torch use, and depending on the rod they may work in a pinch (without the flux). A lot of them contain Zinc which is likely to fume out and make a bit of a mess. I have used alumiweld soldering rods as filler to TIG weld a buckle made from pot metal. It was messy, but got the job done.
What is your current setting? I tried TIG brazing with phosphor bronze (same stuff they use for HVAC) and I couldn't find a line between being able to melt the bronze and melting the copper. It was a VERY fine line, and also the arc was erratic as hell.
Tim I've been waiting for you to do repairs sitting there talking about how to pad out beads and stick weld and used the machine that's all well and good but if you're not putting the practice to the test then what's the sense?????
You are welding and not brazing. Brazing is combining two metals without a filler. Brazing is used on thick metal. I am certified GMA-MIG ICAR welder. You did a good job welding copper.
I would love more of these little project videos. I would love more tig brazing too!
*Did you use copper tig rods? Electropolishing would've cleaned up that discoloration.*
I really like these repairs, there's always something to learn as a novice and also in some ways, these are the projects that most of us weekend welders work on.
If you have a tig welder you can WELD copper. Using some 14-10gauge electrical wiring like Romex works great as filler
second this. works great.

Do you have to use helium as a shielding gas, or is argon possible? What about with AC?
@Rossco139 Never tried ac. You can use both argon or helium or a mix of argon and helium. If you use helium or a mix of the two , you won't need as much amperage. I'll weld up to 1/8 copper with straight argon no problem but for thicker larger pieces I'll add some helium

Yes, I would absolutely appreciate more repair videos! On a side note, I'm totally stealing this table design!

NICE WORK THOUGH! The bead appearance and the clean up really elevated this job to the next level !!
Love to see repairs, especially on the out of the normal stuff. Thanks.

I would enjoy seeing more welding repairs. Always learn something new on your channel!
Thanks again for your time and information, always learning something new, all the best to you and your loved ones

Yes, more please. Thanks Tim.
Yes I love these little techniques I'm a Tig welder I wish I knew how to how to Tig copper I always use a cutting torch with a tip
Thank you. Love your videos. They are informative and straight to the point.
That would be a yes on repair projects I have been watching your videos for some time now and get a lot from them (good job)
Love these videos, it's very helpful to see how you approach a project.
Great video
Yes more projects and more tig brazing
Yes please!

One suggestion is to include some important data points like rod size and amperage in these kinds of videos.
Thanks for the suggestion! I was running 3/32” (2.4mm) silicon bronze at a machine setting of 200 amps. I’ll include more of those details in the next one.
@@TimWelds Wow, that’s really hot! Impressed you didn’t melt the parent metal.
More of these projects would be pretty cool
Cool video small projects are always fun to watch and learn from keep it up

Great info . Please do some more flux core Mig .
I would like to see more hands on repairs/builds on the channel.
Yes to repairs!

I get asked to repair a number of things. Having just purchased a TIG machine, I may have to give this a try.
Very nicely done! Thank you for creating and sharing.
you can braze cast iron too ! and you could not just tig braze but also pulse mig braze .....
Repairs ... Yes.
I would love to see more repair videos
Autosol is a really good ceramic based micro powder polisher. Works on Chrome aluminum titanium and softer materials like bronzes brasses and copper
Really handy Thanks
Looks good Tim, the customer must have been happy
Keep em coming.
Hi was this done on AC or DC love these type of repair videos 📹 keep up the good work
this was done on dc
Half and half projects and education stuff I learn a lot form both
Would love to see repair vids
Thanks for sharing this! I've started playing with Tig brazing on some coupons, I'm curious to know why you chose to braze instead of copper Tig weld?
SIl-bronze is way stronger than most people give it credit for.
Wow, thanks for sharing! Subscribed!

You keep the amps down lower than you would for a weld.

great what size silicone bronze was you using, and how many amps was you using ,any info would be great thanks Mark
Is flux ever used when TIG brazing?
Repairs yes. Question, can you tig braze with regular Oxy/acc brazing rod? Flux on or off?

@@TimWelds thanks for the insights.
Thank u that was very informative
Great video! We're you using DC Tig? I would love to be able to do this but my machine only does DC Tig.
Yeah, standard DC Electrode Negative.
What is your current setting? I tried TIG brazing with phosphor bronze (same stuff they use for HVAC) and I couldn't find a line between being able to melt the bronze and melting the copper. It was a VERY fine line, and also the arc was erratic as hell.
Can welding be done using only argon gas?
What shielding gas did you use?
What that sanding tool called the mawike
💙💙💙
Tim I've been waiting for you to do repairs sitting there talking about how to pad out beads and stick weld and used the machine that's all well and good but if you're not putting the practice to the test then what's the sense?????
How many amp ?
I had the machine set to 200 amps, though I was running a foot pedal with it.
Nice shootin'.
Which gas you in tig?
Straight Argon 👍
what gas do you use for this?
Just straight Argon.
Thankyiu
it looks easy but it is not, i tried and it sucks
