Optimization of twin wire automatic welding process for dissimilar Al-alloy

With automatic twin wire gas shielded arc welding process,dissimmilar aluminium alloy 6061 and 5083 of 5 mm thickness were welded.Influence of the welding process on joint strength and formation were investigated with MINITAB.The results which had been proved by optimizing welding process showed that joint strength can reach and even exceed the standard.The efficiency is twice as high as the manual TIG double side welding.
