Abstract:
20MnMoNi55 is very critical material to weld, as the material is grouped into the P3 category according to the ASME Code, which has lower weldabilty then other steel. The parameters for the welding of 20MnMoNi55 like Welding current, welding speed, Wire feed rate and stick out should be in optimize range. In this research paper the range of the welding parameters are optimized using Design of experiments with help of Taguchi method. Several experiments were performed for finalize the optimum range using Submerge Arc Welding.
