Oxy welding aluminuim is an art. It's possible. All you have to do is master the colour of the puddle. When you can recognize the difference between molten aluminium and solid aluminium. (there's very little difference before the whole thing falls away) you can do a very nice job with gas. Make sure everything is super clean. On both sides of the weld. Inside and out. Plus the joints should be super tight.
My dad was an airframe fitter in the war he taught me when I was 16. I haven't gas welded aluminium for a while but when I do, it's a challenge and a real sense of achievement when the job is done. Have fun.
