Pulse Welding

This paper provides details about the adjacent parallel seam welding of a pair of aluminum sheets by a magnetic pulse welding (MPW) method. An impulse discharge current from a capacitor bank passes through a flat one-turn coil and concentrates on two parallel along the narrow middle parts of the coil. A magnetic flux is suddenly generated around the middle parts. This flux intersects the sheets which are overlapped on the middle parts. The resulting eddy currents are induced in the sheets, applying two parallel strong electromagnetic forces to them. The sheets having a gap collide with each other at high speed in two parallel. In this time, four metal jets occur just ahead of the collision front along the middle parts. Two metal jets occurring in the inside collide with each other if the experimental conditions are suitable.

The Magnetic Field

Magnetic pulse welding is a high-speed welding technology, which is suitable for welding light metal materials. In the magnetic pulse welding system, the field shaper can increase the service life of the coil and contribute to concentrating the magnetic field in the welding area. Therefore, optimizing the structure of the field shaper can effectively improve the efficiency of the system. This paper analyzed the influence of cross-sectional shape and inner angle of the field shaper on the ability of concentrating magnetic field via COMSOL software. The structural strength of various field shapers was also analyzed in ABAQUS. Simulation results show that the inner edge of the field shaper directly affects the deformation and welding effect of the tube. So, a new shape of field shaper was proposed and the experimental results prove that the new field shaper has better performance than the conventional field shaper.
