Experimental Investigation for Parametric Optimization of Gas Metal Arc Welding Process for Welding Of AISI 1018

Mechanical engineering

Gas metal arc welding is a fusion welding process having wide applications in industries. Gas metal arc welding is one of the conventional and traditional methods to join materials. The present study is to investigate the influence of welding parameter on the penetration. The effect of welding current, welding voltage and gas flow rate on the depth of the penetration in gas metal arc welding of AISI 1018 mild steel having 8mm thickness has been going to study through experiments and analysis, and investigate the optimization process parameter. The optimization for gas metal arc welding process parameters of Mild Steel work piece using Taguchi method will done. Twenty seven experimental runs (L27) based on an orthogonal array Taguchi method will performed and investigate the effect of welding parameters like welding current, welding voltage and gas flow rate on depth of penetration. The depths of penetration were measured for each specimen after the welding operations and the effects of these parameters on penetration were researched.
