Effect of Welding parameters on bead geometry of weld by GMAW Process
Rakesh Ranjan,  Ajit Kumar,  Avinaw Pratik
The objective of the present work is an attempt to study the effect of various welding parameters on bead geometry of mild steel specimen having 5.5mm thickness welded by Gas Metal Arc welding process. The welding current, arc voltage and welding speed were chosen as variable parameters. Tests were conducted using CO2 as shielding gas (MAG welding) and shielding gas (MIG welding). The bead height and depth of penetration were measured for each specimen after the welding operation. Further the ultimate tensile strength, Vickers hardness test, flaw detection and grain structure study was conducted and the effect of the variable parameters were studied.
Keywords- welding current, arc voltage ,welding speed, bead height, depth of penetration
