Since we don't have a specific forum for brazing processes, I'll move this over to "general shop talk", which everyone active here visits. (The "how to use the forum" section is intended for instructions on things like posting pictures, linking videos, etc.)
I do a lot of silver brazing, but it's not for color, so I'll defer to others on that subject.

I thought we had athread awhile back about this same subject, but I don't have time right now to look it up. I think it was about matching colors on a brazed frame on a motorcycle.

the bead is very lumpy and there is a lot of porosity
also the filler wire acts like there is not enough heat, it clumps at the end
its on 1/8 mild steel, im on dc
my using gold band tungsten
cfh is at 25 and amps are at 110
aluminum bronze filler.
also tried ac, same results
