Material Hybrid Joining of Sheet Metals by Electromagnetic Pulse Technology
Adhesively joining metals of dissimilar melting point represents one of the most sophisticated tasks in joining technique. However, due to light weight considerations this type of joint, for example the connection between an aluminum flange and a high strength steel crash element, is of prior interest. The electromagnetic pulse technology is a proven process to accomplish adhesive joints between tubes made of dissimilar metals. Recent developments of the technique now allow welding even dissimilar and similar sheet metals under industrial conditions. This paper details the underlying mechanisms and shows a variety of samples, depicting for the potential of this new process.
