Microstructure and Properties of Al Alloy TIG Welding Joints
摘要
Abstract
The microstructure and tensile properties of A1 alloy TIG welded joints were investigated by metalloscopy microscope and tensile test.The results show that the welding surface is well formed,no cracks on the surface,and the mechanical properties were the best when using the ER5183 welding wire.The mechanical properties of welding variable angle joints were lower when using the 5083 welding wire.The surface crack is obviously,and more pores and inclusions in the welding joint when using the copy-ER5183 welding wire.关键词
