Welding Tips and Tricks

Hmm..Colour suggests bronze?

Looks like bronze to me. There is a guy in the UK who posts on Instagram who does some amazing work using a torch that puts the flux in the flame. Seems to be really popular over there for for custom motorcycles

You mean Oxy torch? How to do...And get the 'Stack of dimes'? If gas torch, why, when tig should get a better result?

If I'm not mistaken the flux technique is called vapor-flux. I did a heap of welding with it years ago making motorcycle accessories, clip-on handlebars, carriers, crash bars etc. We linished and polished all the steel tube components first, then used vapor-flux with Oxy-Acetylene and Bronze filler. We could get a real neat stack-of-dimes look, essentially using the same application technique as TIG with aluminium. The flame burns extremely bright because of the flux vapor, which is mixed in to the Acetylene gas line.

Ah, interesting...But what/where is the advantage over plain ol' TIG?

Oxy torch is preferred when heat isn't an issue because the whole process is more gradual, not short and SHARP like tig that results in hardness sometimes

Yes, Mike's spot on. It was a lot more controllable.
Most of the gear we manufactured was then chromed. The result was that you couldn't see how the parts were joined together. With 'artisitc' application of the bronze, after chroming they appeared to be one single component

(And also, this was in the 70's - hardly anybody had a TIG welder in those days!)

Groovy

Ok, I see it all much more clearly now. Thanks

we use a Silicon Bronze or Aluminum Bronze welding rod sometimes if we are trying to add a softer pad
that is what it looks like to me . Tig weld

i'm going to have to look for that youtube video sounds cool

yep looks like braizing, seen it done a lot on bikes. +1 to the guy on instagram overseas that does braizing. _kamfab or something
