    Tig Brazing

    Anyone ever seen in person or used this method? Was thinking a future pipe might look cool done up with it.

    looks wicked trick. Would look awsome on a pipe. Dont know about for structural strength though, isnt brazing, even with tig, just a surface bond? I dont think you get the same burn in on the base metal with a braze. Looks like maybe some silicon bronze rod, which is super tough, and will bond dissimilar metals.

    Hey Billy,

    I've TIG soldered steel with brass rod before on some pretty stressed parts (lower drag bar mounts) My TIG mentor swore it was a very strong way to attach things to each other, but like the guy in this video say, it won't be as strong as steel to steel, but I'm guessing the welds won't stress crack as the brass is softer. I don't think brass paints well, but for a pipe it should work great. In fact I believe many spring hooks on 2 stroke pipes are brazed on.

    On a sextional exhaust, think it would break apart.Once it starts your screwed.Especially on a.pipe like your building.Not worth the chance.One thing I would have done is purge welded your pipe.Plus used 309 SS tig wire.It would turn out nice and be strong.

    I am just learning to use a TIG but I can't imagine brazing a pipe, that's pretty thin material. As stated above if it starts to open up you're done. It would look beautiful though...

    Fusion weld with gas maybe, Billy?
    My son and I did some playing around with our oxy/propylene smith this past weekend. I was surprised how well fusion/no filler worked on an old roached out FMF. Kenny Roberts fusion welds and then hand pounds each section smooth (no filler). Think he uses oxy/acetylene though. He only brazes the exhaust port bell and spring hooks. Awesome work you do! Love watch'n!

    Thanks for the feedback everyone. I ordered a small 1lb package of Silicon Bronze rods from McMaster to try and do the bracketry on the pipe with as a starter - we will see how that works out before I get any more ambitious

    We did a fair batch of silicon bronze with the tig back at the street rod shop... I think it would hold up on a pipe...
    No trikes. Too old, too crippled. Unless I find one I can't live without!

    About $20 a lb is what it worked out to be. I didn't buy more than a lb

    We use that rod all the time at work. I seen the welders braze 26ga material together. You can also use a stick welder as the heat source, but need a carbon rod instead of the regular welding rods. I have patched up a few mufflers with it and haven't had any problems.

    There were motorcycle frames that were brazed in the 1960" & 70"s (American Eagle & Rickman to name a few) They didn't have any problems.

    Many bicycle frames are still brazed today, including downhill bikes.

    Many old 2 stroke aftermarket pipes had brazed exhaust flanges, pipe spring holders, mounting brackets and mounting nuts.

    An old welder told me it helped with vibration issues.

    As soon as Bill's pipes started Migging everything it seems everyone followed.

    I have used Harris 56 to tig weld with. Mostly socket welding dissimilar metals like steel to copper or copper to stainless ect. The next time I start up the tig welder I will try to butt weld 1.5 SS tubing. Test it's durability.
