I got myself a couple silicone bronze rods from the local welding shop the other day and have been having a go with them today.
I had a go with DC and AC and found that DC was a bit nicer (although I read elsewhere that AC is better?).
I found that when the rod was put under the arc and started melting it hissed, fuzzed, and kicked out some horrible nasty smoke. The weld bead was left with black soot all over it and it basically just looked nasty... with a quick wire brushing it shined up nicely and looked like a pretty good weld...
I had the amps pretty low, there was barely a weld puddle forming on the base metal (mild steel) when the filler was added.
On the left is before I attacked it with a wire brush, on the right is after.
What I want to know is if this is what usually happens, or if I'm doing something wrong?
I want to use this silicone bronze stuff to stick some EN3B bottle cage mounts into a 4130 down tube of a bicycle. I don't have the equipment for normal brazing, but if you know of a better way, I'm all ears!
Cheers,
Burf
