I'm finishing my first frame. The welds have gone well, except for the last one. The mother fing seatstay-steattube joint. I know I've put too much heat into the area trying to get the tungsten into cramped joint. When I finally was able to lay a bead it was bubbly and left pits. I've been told its from overheating or contamination. I've cleaned off the area with a wire brush and let it cool but I'm still getting the pitting. Its only like a half inch long area.
Is grinding the bubbled area down my best option? Anything else I should try? Thanks!
