The resistance spot welding is performed in samples with dimension as shown in figure 3 using this welding parameter.

Welding sample dimension Fig. Load displacement graph Four samples were prepared and spot welded with parameters as stated in table 3. Sample 1 has shear tensile strength of High shear tensile strength is for the sample 4 which is preheated and quenched in 3.

Result and Discussion water. Quenching in the water alone can increase the shear This study comprises of four groups of comparative tensile strength of the weld slightly. This is evident from the experiments. Four welded sample prepared according to the shear tensile strength of the sample 3 which is only quenched welding parameters in table 3 are shown in figure 4.

The first in water not preheated. The second sample 4. Conclusion has an additional pulse current preheating current of 5kA along with the welding current and it is cooled gradually in air. The tensile strength can be increased by adding preheating Third sample has no preheating current but it is quenched in current to welding spot and quenching weld in water.
