In the present work, bead-on -plate welds were carried out on 304L austenitic stainless steel using synergic MIG process. In this present investigation 304L having 1.2 mm diameter was used as an electrode with direct current electrode positive polarity. Argon and CO2 was employed for shielding purposes. The fusion zone is defined by a few geometrical characteristics, such as bead width, bead height, and penetration depth. A number of factors influence the configuration of the fusion zone, including gas flow rate, voltage, travel speed, and wire feed rate. Micro hardness measurements were done over the weld bead base material to better understand the Knoop micro hardness.
