Insulating cushion materials for electromagnetic pulse welding and methods for controlling deformation of flyer plates

Abstract

Disclosed is an insulating cushion material for electromagnetic pulse welding a method for controlling deformation of a flyer plate in electromagnetic pulse welding using the insulating cushion material. The insulating cushion material includes rice grains or bean grains. The method includes: preparing a base plate and the flyer plate for welding, and cleaning and drying the base plate and the flyer plate; determining an overlap spacing and a collision gap based on specifications of the base plate and specifications of the flyer plate; selecting the insulating cushion material based on the collision gap; placing the insulating cushion material between the base plate and the flyer plate based on the overlap spacing; starting an electromagnetic pulse apparatus and performing electromagnetic pulse welding according to a set process parameter; cleaning broken particles of the insulating cushion material between the base plate and the flyer plate after completing the electromagnetic pulse welding.
