Ni中间层对6061T6铝合金板/08Al异种金属电阻点焊接头的力学性能及组织的影响
Effects of Ni Interlayers on Mechanical Properties and Microstructure of Resistance Spot Welding Joints of 6061T6 Aluminum Alloy Plates/08Al Dissimilar Metal
摘要
Abstract
By adding Ni interlayers to steel plates,the reliable connections between 6061T6 alumi-num alloy plates and 08Al steel plates were successfully realized,and the mechanical properties of alu-minum/steel spot welding joints were significantly improved.The results show that the thickness and distribution of Ni intermediate layers on steel plates may be controlled by using the prefabricated Ni intermediate layer processes,and the formation of Al-Fe brittle intermetallic compounds may be re-duced.Compared with adding Ni foil intermediate layers directly,the prefabricated Ni intermediate layer processes may effectively increase the nugget diameter.The maximum tensile sheer force of alu-minum/steel resistance spot welding joints with laser cladding Ni layer on steel plates is 35.5％higher than that without intermediate layers.关键词
