Abstract

Flux cored arc welding (FCAW) is a semi-automatic or fully-automatic welding method that is widely used for welding large sections and with materials of great thicknesses and lengths, especially in the flat position. In the present work a MIG welding setup has been used to join boiler quality steel. For the experimentation, three process parameters namely, shielding gas flow rate (G), wire feed rate (F) and voltage (V) with five different levels are selected after trial run within the scope and limitation of the MIG welding setup. All the welded samples have been studied through visual inspection, tensile test, and micro-hardness test. Grey relational grades obtained from the grey relational analysis have been used to optimize the process parameters of FCAW process of boiler quality steel with multiple performance characteristics (deposition rate, percentage of elongation, ultimate tensile strength and average hardness of fusion zone) using Taguchi S/N ratio concept on the results of grey relational analysis. The optimization of the complicated multiple performance characteristics is greatly simplified through this approach. The relative importance among the welding process parameters on the multiple performance characteristics has been analysed through Analysis of Variance (ANOVA) method.
