Systematic Welding Process Parameter Optimization in Activated Tungsten Inert Gas (A-TIG) Welding of Inconel 625

This article presents the welding process parameter optimization for activated tungsten inert gas welding of a 6.5 mm thick Inconel 625 plate. The experimental design L 25 has been undertaken to obtain optimal parameters for inputs, including welding current, torch travel speed and arc gap on penetr...
