In the present work, the effect of heat input on weldability of austenitic stainless steel (AISI 304) in pulsed current GMAW has been investigated. The weldability has been investigated in terms of tensile properties (Ultimate Tensile Strength (UTS), Yield Strength (YS), and % elongation). Further results have been verified by SEM analysis and porosity content. The welding parameters were adjusted to achieve a weld bead contour corresponding to DIN 8563 class AS at different heat inputs.
