Spot Welding. Spot welding (or resistance spot welding, RSW) is the most applied resistance welding process for joining sheet metals. The spot welding process starts with pressing two pointed copper alloy electrodes at the location to be welded. While two electrodes hold metal sheets, the welding current flows through the spot and generates …
To calculate the power consumption, you need to use this formula: Power (in watts) = Voltage x Amperage. For instance, if your welding machine is rated at 240 volts and 60 amps, you would multiply them together to get 14,400 watts (240 x 60). The duty cycle is how long the machine can operate continuously without overheating or causing damage.
In achieving a perfect weld, a range of variables come into play: Electrode Force: Dictates the quality of the weld. Squeeze Time: The lull between applying force and initiating the current. Welding Time: The span during which the current actively flows. Holding Time: Period for the nugget to solidify.

Spot welding is a type of resistance welding that uses heat generated by electric current to fuse the two pieces of metal together. In this process, two electrodes are placed on either side of the metal pieces and an electric current is passed through them to create heat. This heat melts the metal and causes it to fuse together.
