Abstract: This work investigates the influence of welding parameters on the impact strength of welded Mild Steel joint, providing valuable insights for the manufacturing and construction industries. The specimens having dimensions of 55 mm? 10 mm? 10 mm were welded by metal inert gas welding (MIG) for single V - Butt joint. The selected levels for welding current are 240 A, 250 A, 260 A; while the levels of wire feed rate 2 m/min, 3 m/min and 5 m/min. Statistical analysis of the experimental results show that welding current, wire feed rate and their interaction have significant effect on the toughness of the welded joint. The optimal set of process parameters for optimal toughness. (299 joules) found to be 240 welding current and wire feed rate of 3 m/min.
