GMA Spot Welding of A7075-T651/AZ31B Dissimilar Alloys using Stainless Steel Filler

The aim of this research was to investigate the welding joint's fracture toughness and fracture surface morphologies between A7075-T651 aluminum and AZ31B magnesium dissimilar alloys welded using a new technique of gas metal arc spot lap welding with unconventional ER308L-Si stainless steel fil...
