There was gas welding of aluminum long before there was TIG. My Mom was a welder at Curtis Wright before North American Aviation took over.



They trained the ladies to weld aluminum with just blue glasses a gas torch and some water based flux on the filler rod.

The next time you see a war bird at an airshow, look for an oil tank. Gas welded BT, (before TIG).



I have a 600 amp Hobart, so it has never come up, but this year at the Sun&Fun flyin at Lakeland Florida I took a turn at gas welding aluminum. I was giggleing like a school girl. It is so easy, and the weld is so nice looking. When I get some time I will make a setup to practice until I get 1/10 as good as my Mom was.

The picture is from the bottom of the engine just after a race. Those are scavenge out lines to the pump. The rod end thingy prevents fore and aft movement of the engine.

I would really rather avoid sending theem out, but will if i have too,.. anyone know a shop in the bay area thats rotary literate?

Mariah Motorsports in Monticello/Santa Barbara can do it. They'll charge $50 labour (one hour labour). How far is that from you?
