FUNDAMENTALS OF EXPLOSIVE WELDING

An account is given of the basic mechanism of adhesion in all welding processes, and a brief review of fusion and pressure welding techniques is given. A completely new method of welding which employs high explosives is briefly described and explained in terms of the principle used in the hollow charge, which wm developed during days of war to defeat heavy armour plate. The results of experimmta carried out to find the mechanical properties of explosively welded joints are discussed and the application of the principle to the problem of welding tubes into end plates is described. Results of metallurgical examination of the welded joints are presented and discussed and the mechanism of the formation of the interfacial waves is briefly mentioned. © Taylor and Francis Group, LLC.
