Chewed up campy dropouts

Won't that melt the brazing

Laying continuous beads would run that risk but the way to do it would be like welding thin sheet. Short pulses of weld with a pause between each pulse to allow the dropout to cool. Not a great technique for sheet because it runs a risk of pin holes and cold joints but this is just to fill the gouges.

TIG makes a narrow heat band, this is probably your best welding type.
