The Effect of Metal Inert Gas Welding Parameters on the Weldability of Galvanised Steel

Keywords: Metal inert gas, Percentage elongation, Process parameters, Taguchi method, Ultimate tensile strength, Yield strength


The Taguchi technique is employed to establish the optimal parameter for each tensile property of the weldments. The tensile properties determined are the ultimate tensile strength, the yield strength, and the percentage elongation, whereas the process parameter used is the welding current (A), welding voltage (B), and the gas flow rate (C). By applying the Taguchi method, the optimal process parameters for obtaining the weldment with better yield strength are A3B1C3, whereas A3B3C3 can produce the weldment for better elongation. These optimum process parameters have shown considerably improved signal-to-noise ratios over the current process parameters adapted by the welders.
