The aim of the work reported here was to utilize Taguchi methods to optimize Bending Strength in the welding of EN24. The parameters of Bending Strength are analyzed under varying welding currents (24.8A, 29.2A, 38.5A.), Weld Time (5Sec., 10sec, 15sec.) The settings of welding parameters were determined by using Taguchi Experimental Design method. The signal to noise ratio is employed to determine the effect of welding parameters on Bending Strength. The conclusion from the study is that Time is the most significant factor than current for Bending Strength response; Bending Strength displaying an increasing trend with an increase in time & Current parameters, for maximum Bending Strength current is to set at max. level.
