By comparing backgouging of plasma arc with carbon arc to the welded joint of 13-5 martensitic stainless steel, the backgouging of plasma arc is proved feasible for the full penetration weld.
Do spot welding experiments to aluminum alloy plate in the same condition of simulation, prepare low magnification metallographic photos of joint, and measure nugget diameter and penetration rate.
