6063铝合金/紫铜接头异种金属新型钎焊工艺研究

Research on the new brazing process with dissimilar metal of 6063 aluminum alloy/red copper joint

探索了一种用于6063铝合金/紫铜连接的异种金属新型钎焊连接方法,该方法以锌铝药芯钎焊丝为焊接材料,结合了TIG焊的特点和钎焊的特点,操作方便,效率高.通过与传统炉中钎焊进行比较,对其润湿性,接头抗剪强度和微观组织进行了分析.结果表明:采用新型钎焊方法能够有效实现对6063铝合金/紫铜接头的焊接,并且得到较高的接头抗剪强度,最高可达70.2 N/mm^(2).

A new brazing process with dissimilar metal for 6063 aluminum alloy/red copper joint was developed.This method uses zinc-aluminum flux cored wire as welding material,combines the characteristics of TIG welding and brazing,and has the advantages of convenient operation and high efficiency.The wettability,shear strength and microstructure of the joint were analyzed by comparing with traditional brazing in furnace.The results show that the new brazing process can effectively realize the welding of 6063 aluminum alloy/red copper joint,and obtain higher joint shear strength,up to 70.2 N/mm^(2).
