EFFECTS OF WELDING PARAMETERS ON PERCENTAGE DILUTION IN 316L GMAW CLADDING

Abstract

The welding is the well-known metallurgical sculptural process for the fusion of metals and also to increase the surface properties in the case of cladding. The Gas metal arc welding (GMAW) is implemented to achieve the improvement in the surface properties of the base metal. The deposition of 316L stainless steel onto the structural steel is presented in this paper. This cladding gives the weld bead geometry which shows how far the electrode material has influenced the work piece. The extent of dilution of the electrode material or the stool over the base material is to be minimized. At the same time the weld quality has to be increased. The control parameters for this cladding process are the welding voltage (V), wire feed rate (WF), welding torch speed (S), gas flow rate etc. This is to predict the well suiting parameter that satisfies the weld quality and the desired results. These parameters affect the outcome responses such as welding geometry, reinforcement height, penetration depth, percentage dilution, height and width of the weld bead and the ferrite number. The weld bead geometry is constructed using the AutoCAD for predicting the desired parameter. It shows the levels of percentage on which the dilution has been resulted.
