Titel
Shock welding: Process variants and measuring procedures for assessing the welding quality
Abstract
The prerequisites necessary for joining using shock welding processes were investigated within the framework of a research project. Both explosive welding and magnetic pulse welding were considered. In this respect, the investigations encompassed process requirements as well as defined parameters. The shock-welded joints were classified on the basis of the evaluation of metallographic specimens using a light microscope and the technological limits of the process were described. The determination of the degree of hardness H, the welding zone length lSZ and the adhesive shear strength tH served to establish the welding properties. The bonding zone of the welded joint was investigated with the EDX (energy-dispersive X ray spectroscopy) procedure using scanning electron microscopy (SEM).
