An Overview of Welding of Aluminium Alloys through Pulse – Gas Metal Arc Welding Process

Abstract

Newer aviation and automobile designs intend at minimizing weight. Motivated by this requirement light metal industry is experiencing some stimulating developments. One of the mainly used light metals is aluminium. As aluminium is exploited as a substitute material, many challenges have been emerged in front of manufacturers. Some of them are development of new aluminium alloys, joining of diverse types of aluminium alloys and enhancement in weld quality of welds and weld repairs. One of the technologies being identified by the fabricators of aluminium is pulse gas metal arc welding (GMAW-P). This paper elaborates about metal matrix composites; the difficulties in joining of different types of aluminium alloys and how GMAW-P can help in fulfilling newer challenges of welding of aluminium are discussed
