Abstract

This paper investigates the effects of process parameters on weld bead width of austenitic stainless steel SS-310 in tungsten inert gas welding. The four parameters namely welding current, type of gas, gas flow rate and included angle of weld plates during butt joint were varied at three levels. The DOE approach was used to design experimental conditions. Orthogonal array L9 was used for carrying out experimentation. The optimization of weld bead width in tungsten inert gas welding of austenitic stainless steel alloy was done using ANOVA. The minimum value of bead width of SS 310 is 8.27 mm at current value 130A.
