TOPSIS is an extensively used multi-criteria decision making tool. It is simple in form and easy to apply in complex decision making problems. In the present work, TOPSIS is applied for selecting appropriate process parameters for Gas Metal Arc Welding (GMAW) of High-Carbon Steel specimens. Experiments were performed on specimens using MAG welding with varying process parameters. Experimental outcomes are analyzed and the results obtained from the TOPSIS process are depicted in ranking the best alternative corresponding to a set of process parameters. It is found that160 A of weld current, 30 V of weld voltage and welding torch speed of 370.5 mm/min setting with the highest heat input in the present investigation is giving the best result according to TOPSIS.

Abstract


TOPSIS is an extensively used multi-criteria decision making tool. It is simple in form and easy to apply in complex decision making problems. In the present work, TOPSIS is applied for selecting appropriate process parameters for Gas Metal Arc Welding (GMAW) of High-Carbon Steel specimens. Experiments were performed on specimens using MAG welding with varying process parameters. Experimental outcomes are analyzed and the results obtained from the TOPSIS process are depicted in ranking the best alternative corresponding to a set of process parameters. It is found that160 A of weld current, 30 V of weld voltage and welding torch speed of 370.5 mm/min setting with the highest heat input in the present investigation is giving the best result according to TOPSIS.
