Advancements in explosive welding process for bimetallic material joining: A review

Abstract

The increasing demand and complexities within the manufacturing sector to fabricate composite materials, particularly bimetallic products for the manufacturing industry, have led to the introduction of various joining processes. Notably, explosive welding which is a solid-state welding process has emerged as a highly advantageous technique for the fabrication of composite materials for lighter weight and durable vehicle components. This review aims to provide a comprehensive study of the explosive welding process. The complexities of the explosive welding methodology are explained, incorporating a comprehensive examination of the influence of experimental parameters on the mechanical and microstructural characteristics of the resultant welded composite materials. Additionally, the review consolidates current research pertaining to underwater explosive welding of bimetallic materials and the joining of different configurations using explosive welding. The challenges encountered during the welding process are discussed and solutions proposed by various researchers are presented.
