Optimasi parameter resistance spot welding pada pengabungan baja electro-galvanized menggunakan metode Taguchi

The present study features analytical and experimental results of optimizing resistance spot welding performed using a pneumatic (electrode) force system (PFS). This optimization was carried out to incorporate the galvanized steel sheet material SECC-AF (JIS G 3313) SPCC-SD 3141) plate coated with zinc thickness about 2.5 microns. coating on metal surface causes its weldability decrease. aims obtain highest tensile shear strength test from combination specified parameters. research method used Taguchi four variables tingkats. study's tingkat is two tingkats in first parameter three other show that obtained 5049.64 N. achieved at 22 cycles squeeze time, 25 kA current, 0,6-second welding-time, 12 holding-time. S / N ratio analysis found time had most significant effect, followed by holding time. delta values were 0.62, 0,41, 0.34 0.07, respectively.
