Abstract:Parametric optimization of Pulsed Current Metal Inert Gas Welding(PCMIGW) for Ultimate Tensile Strength and Hardness has been performed by using Taguchi method. Welding Current, Gas Flow Rate and Wire Feed Rate were chosen as welding parameters. The material used for this purpose was ASTM A106 pipes having dimensions with outer diameter 25 mm length 300 mm having wall thickness of 3 mm. Argon (85%) and Co2 (15%) was used as a shielding gas. Mild steel filler wire with copper coated of diameter 1.2 mm was used.… Show more
