Multi-criteria decision-making approaches in welding processes: A review

Welding is a technique used to join, repair, and manufacturing new products. In welding to select the best parameter, several optimization techniques were available, and among them, Technique for Order Performance by Similarity to Ideal Solution (TOPSIS) algorithm is one. TOPSIS algorithm is also one of the optimization processes that also used to generate various welding process parameters. In this paper, the main focus on TOPSIS algorithm used in various welding. The review work on the TOPSIS method used in the welding process like TIG welding, laser welding, friction stir welding, manual metal arc welding, and other advanced types of the welding process, for an enormous scope, was not performed prior. This review work will be future information for the ensuing researchers, to find out their exploration in research for working on TOPSIS algorithm.
