One of the difficulties of gaswelding aluminum i think is welding over the tacks. When
you've adjusted the torch to make the final weld and you're going fine till you must
run over a tack. In my experience the setting with gaswelding is for a tight material
thickness( I don't know how to explain it in an other way) When you reach the tack, which
is a bit thicker, the flame has insuficiant heat to let it melt in the same way as it
could with the sheet. I tackle this to grind the tacks to the same thicknes as the sheet
, which works well, but this is timeconsuming and you have to be careful not to ruin the
sheet. Sounds this familiar and is there an easier way to solve this? All suggestions are
welcome.
Cheers Richard.
