Influence of Process Parameters on Weld Bead Geometry and Mechanical Properties in GTAW

In this paper, the structural and mechanical properties of IS:2062 mild steel after single-pass gas tungsten arc welding (GTAW) were investigated and evaluated, to reveal the weld strength and microhardness of welded joints. The properties of the welded joint are affected by various welding parameters, such as welding current, welding speed, gas flow rate and groove angle. This work concerns with mild steel plate joining with bevel angle (30°–50°) and also using filler material same as the base metal. The quality of welds will depend on the modeling of weld bead shape.
