Is 2062 E250 mild steel plates to be welded using CO2 as shielding gas. Welding speed is select as process variable while arc voltage, welding current, wire feed rate distance between the nozzle and the plates are fixed in this experiment. The effect of weld speed on the weld bead profile is been discussed with the effect of weld speed on he fusion angle and wetting angle. The effect of weld speed on the weld bead dilution i.e. penetration area and reinforcement area also be discussed.
