Investigation of Welding Parameters of Dissimilar Weld of SS316 and ASTM A36 Joint Using a Grey-Based Taguchi Optimization Approach

A grey-based Taguchi method was applied to investigate the optimal operating conditions in shielded metal arc welding (SMAW) join SS316 and ASTM A36. This work aims set parameters for mechanical properties of weld joint. The effects various factors on electrode type, current, welding, speed have be characterized optimized achieve an optimum condition. An L9 orthogonal array used group components. a dissimilar joints were described through hardness, tensile flexural strength tests. obtained simultaneously as type E309, current 100 A, voltage 14 V, 4 cm/min, which predicted improve 23.0% its performance.
