Regular old brazing rod > doesn't work well with TIG. I did some TIG brazing recently to have a filler material that would hold up to powdercoating temperatures. It worked pretty well on some 16 gauge 1" square tubing I built tables out of. I filled in some undercutting and a few other sins, ground everything flat and sanded it before sending to the powdercoat shop. It came back looking great! With the Silicon Bronze rod, you can still overheat it, but it takes a good bit of heat. It's kind of cool the way the metal flows toward the heat, just like my old O/A brazing days.

I just double checked, the filler I am using is marked Silicon Bronze and it says on the label that it is suitable for for TIG, Plasma or O/A brazing on steel. It is marked AWS 5.27.

I thought we already had this talk. Am I going to have to come down there and slap the crap out of the counter guy at the welding supply store? Similar Threads Posted Hey, Ernie ......
