摘要
由于铝合金和铜异种金属之间的物化性能差异较大,铝合金具有强氧化性等因素,铝/铜异种金属连接是焊接领域的研究难点.综述近年来铝/铜异种金属熔钎焊的研究现状,介绍了铝合金和铜异种金属的焊接性,评述了铝/铜异种金属电弧和激光熔钎焊的研究进展,讨论了铝/铜异种金属熔钎焊仍然存在的共性问题;通过采用合适的焊接工艺配合合金元素调控是解决铝/钢异种金属熔钎焊问题的关键,并对该领域的研究发展进行展望和评述.
Due to the great difference in physical and chemical properties between aluminum alloy and copper dissimilar metals,the strong oxidation property of aluminum alloy and other factors,it has become a difficult point in the welding field of dissimilar metals joining.The research status of aluminum/copper dissimilar metal welding-brazing in recent years and weldability of aluminum and copper dissimilar metal were reviewed,common problems of the aluminum/copper dissimilar metal welding-brazing were discussed.Appropriate welding process with adjustment of alloy elements is the key to solve the problem of aluminum/steel dissimilar metal welding and brazing,and the research and development in this field are prospected and reviewed.
