Abstract
Gas Metal Arc Welding (GMAW) is widely applicable across various sectors due to its ease of operation, higher welding speed and high production rate. The present work aims to determine the effect of welding speed in a synergic GMAW process with ER-NiCrMo-3 wire to produce a bead-on-plate on AISI 4140 base material. The results showed that the beads produced were free from defects like porosity and cracks. The increase in welding speed decreases heat input (HI), bead penetration and weld width. However, the effect of speed was found least in heat input and most in bead penetration. The variation in bead geometry hence, clearly suggests that welding speed plays a significant role in the selection of weld parameters during the fabrication of IN-625 joints.
