In this research work the experimental investigation of TIG welding process on ss317 alloy pipe with different process
parameter viz. Welding current, voltage, and gas flow rate with L-9 orthogonal array design of experiment. Bending and Tensile
test are performed for all 9-test sample as an output parameter. Optimization of process parameter is done via ANOVA and
Taguchi method using MINITAB 18 software.
