Gang, Just got through reading older posts concerning gas (O/A) welding of aluminum - and am absorbing a lot - however, all the posts were concerned with welding .025 up to about 1/8" "nice" aluminum. What about a heavier aluminum *casting*. Suggestions, please. And I'm still talking about O/A techniques..... BTW - I have all the stuff from "tinman" - lense, flux, wire, etc.... I haven't tried just plain aluminum in thinner sections but went straight for the heavier casting and had no luck. Is it possible? Thanks. Ken.

It seems to be possible. But I wouldn't even think to try. I have seen OA welds on aluminium 10mm thick (on a MAN double acting, 2 stroke marine diesel). I think it takes a **lot** of training.

Heat! You need more heat!
All things are possible!
I have TIG welded some 1/2 inch thick sections and it took all the heat I could get out of a 300 amp welder. Plus some. Preheating with a rosebud helped.
