Keith Hartley Memorial Award Lecture 2021: Recent Developments in Materials Joining and Welding

Abstract

.Joining and welding is an essential component of manufacturing technology. New developments in joining and welding are evolved in order to acquire extraordinary benefits such as unique joint properties, synergistic mix of materials, cost reduction of component, increase productivity and quality, complex geometrical configurations, suitability and selection of material to manufacture new products. This paper provides an update on recent developments of welding and joining to showcase above benefits. Theoretical background, process parameters, novel aspects, process capabilities, and process variants along with its application are presented in this paper. The recent research works carried out in Centre for Materials Joining & Research (CEMAJOR), Annamalai University on advanced welding and joining techniques such as friction stir welding (FSW), diffusion bonding (DB), linear friction welding (LFW) , gas tungsten constricted arc welding (GTCAW), rotating arc gas metal arc welding (RAGMAW) and wire arc additive manufacturing (WAAM) are discussed in this paper.
