Robot automation systems are rapidly taking the place of the human work force. One of the benefits is that this change provides the human work force with the time to spend on more creative tasks. The highest population of robots is in spot welding, spray painting, material handling, and arc welding. Spot welding and spray painting applications are mostly in the automotive industry. However, arc...

Abstract The resistance spot welding (RSW) method was used to join aluminum alloy AA 1050 and copper UNS C50100 sheets. Mechanical properties of the joints were examined. influence process parameters on tensile shear force discussed. design experiments (DOE) analyze mechanical joints. Three RSW used: current, squeeze time, time. results showed that joint stress increased with increasing current...
