Numerical investigation on weldability of workpieces using magnetic pulse welding process

Abstract

Electromagnetic pulse welding is a new and very innovative production process. The working principle of the magnetic pulse welding (MPW) process is based on the use of electromagnetic forces to deform and to weld workpieces. Since this sophisticated welding process doesn't use heat to realise the weld, it offers important advantages with regard to the conventional welding techniques. The present study investigates the weldability parameters of joining cylindrical or flat workpieces using MPW process, particularly in industrial applications. The present study deals with numerical modelling of the MPW process applied to plates and tubes. The electromagnetic and mechanical models were coupled using FEM software COMSOL Multiphysics.
