  • Manojkumar V. Sheladiya

Abstract

20MnMoNi55 is very critical material to weld, as the material is grouped into the P3 category according to the ASME Standard, which has lower weldability then other steel. The various parameters affecting the welding of 20MnMoNi55 like Welding current, welding speed, Voltage, Wire feed rate, stick out etc. should be in optimizing range. In this research paper, the attempt has been made to optimize the welding process parameter using Design of Experiments with help of Taguchi method. A number of experiments were performed for finalizing the optimum range of welding current, welding speed and voltage using Submerge Arc Welding(SAW)
