Abstract Resistance spot welding (RSW) is a welding method using the principle of resistance welding with non-fusible electrode where, apart to the rise in temperature for obtaining the melting point of the metal, high mechanical pressure is also added. Two non-fusible copper electrodes compress metallic sheets to be welded and then pass a very high current through these sheets. In the presented experimental work, we are interested to see the influence of electrodes’ positions in the resistance spot welding process. The tensile shear tests are studied with different positions of electrodes. This aims to show the best positions of the electrodes in the resistance spot welding process. Keywords: resistance spot welding, electrode positions, tensile shear tests, peak load, AISI 304 |
