Abstract

Abstract: Tungsten inert gas welding (TIG) is being extensively used as a crucial process in the modern automotive, aerospace, manufacturing and electronic industries as it can produce high quality welds with an appreciable accuracy. Quality of the weld and joint efficiency is the most obligatory requirement. Present work focused on evaluating the mechanical properties for TIG welding aspects of SS 310 and MS materials. An attempt has been made to investigate the influence of various parameters namely welding current, diameter of filler rod and gas flow rate on the responses such as tensile strength, percentage elongation and Rockwell hardness. Welding is performed to join 1.5 mm thick SS 310 and MS plates which were then made to ASTM standard tensile specimens to carry out the tensile test. The mechanical strength is also evaluated using Rockwell hardness test. The results revealed that it has a maximum tensile strength of 424.312 Mpa welded with 60 Amps and having a gas flow rate of 6 Lit/min by employing a filler rod of diameter 2 mm. Moreover, the maximum hardness value of 61 HRB was reported with the sample welded with 40 Amps & 5 Lit/min of gas flow rate by using a 1.5 mm diameter filler rod.
