Interference-fit joining of Cu-SS composite tubes by electromagnetic crimping for different surface profiles

Kumar, Deepak; Kore, Sachin D.; Nandy, Arup

2021 Welding in the World

doi:10.1007/s40194-021-01081-8

This paper explores the possibility of producing an improved interference-fit tubular joint between pure copper and stainless steel tube by electromagnetic crimping (EMC). Successful joints are obtained with optimal parameters consisting of the outer surface profile of the inner tube and...
