摘要

Electromagnetic pulse welding (EMPW) utilizing a magnetic field shaper for dissimilar sheet metals is a newly developed and high promising welding technology. Currently, there is a lack of research on this welding process concerning the plastic deformation of the workpiece and formation of metallurgical interfaces. To solve this, this paper initially employs the finite element simulation method to simulate the electromagnetic and structural fields, elaborating on the macroscopic and microscopic plastic deformations, as well as the local temperature variations in the workpiece under the action of electromagnetic forces during welding. Subsequently, welding experiments were carried out using 1 mm thick 1060 aluminum plates and 316 stainless steel plates. A microscopic examination of the welding interface was then performed, revealing that the numerical calculations align with the experimental outcomes.
