It seems people avoid welding aluminum, but I don't know why. The kids in my high school group that welded the electric car together with zero prior welding experience managed to get it done with a MIG welder. The sole brake plate (stopping is an afterthought when figuring how to win a race) only broke off once. I advised the driver on the radio to not touch the brake pedal under any circumstance, and to proceed racing as if there was no brakes (which was accurate). I wonder why PGE stopped sponsoring that race series?
