Influence of Process Parameters on Depth of Penetration in GMAW Process by Using Taguchi Method

S. D. Ambekar ^[2] | Sunil R. Wadhokar

Abstract: This study is to investigate the influence of process parameters on depth of penetration in Gas metal arc welding (GMAW) process. The optimization for Gas metal arc welding process parameters of Martensitic Stainless steel work piece AISI 410 using Taguchi method is carried out. Sixteen experimental runs (L16) based on an orthogonal array Taguchi method were performed. This paper presents the effect of welding parameters like welding speed, welding current and wire diameter on penetration. The ANOVA and signal to noise ratio (S/N ratio) is applied to identify the most significant factor and predicted optimal parameter setting. Experiment with the optimized parameter setting, which have been obtained from the analysis, are giving valid the results. The confirmation test is conducted and found the results closer to the optimize results. These results showed the successful implementation of methodology.
