摘要
Abstract
A7N01-T5 aluminum alloy was welded by ER5356,ER5183 and ER5087 wire,and the mechanical properties were analyzed.The results show that the residual stress of these three joints are similar;the ER5183 wire joint has the highest tensile stress and elongation after fracture and the best bending property which are resulted by the low number of welding blowholes in the joints;ER5356 wire joint has the highest impact energy in its weld seam and heat affected zone while the value of ER5087 wire joint is much lower.Taken together,ER5183 wire has a better matching with A7N0 1-T5 aluminum alloy.关键词
