Keywords:
Thermal, Convectional Welding, Advanced Welding, Friction stir weldingAbstract
The welding joints formed from the method of advance welding technologies shows higher mechanical and thermal strength as compared to conventional welding technology. This review article discuss the basic principles of advance welding techniques like friction stir welding and laser submerged arc welding with solid state lasers and their advantages over the conventional welding technology. The basic study includes the terminology, process of conduction, thermal, mechanical strength and defects generated. Aluminum is taken as the base material because of its utilization in many industries like aerospace and shipping industry .The comparison has been done on the basis of strength of joints formed, thermal conditions, defects and their effect on environment. The applications of advance welding technology are also taken into consideration for the comparison. It provides us the view of modern practices done in the field of advance welding technology and also explains the future research area and modification
