Zhongbang Welding Machine even said that there is a "spot welding step" about the spot welding machine. 1. First of all, we must observe the spot welding step of the spot welding machine. Generally, the surface of the weldment should be cleaned and assembled accurately, and then sent to the upper and lower parts. Apply pressure between the electrodes. 2. The contact surface of the two workpieces is heated by power on, and partially melted to form a nugget; after the power is off, the pressure is maintained, and the nugget is cooled and solidified under pressure to remove the pressure, and the workpiece is taken out. 3. In this process, it is necessary to pay attention to the spot welding process parameters such as welding current, electrode pressure, energization time and electrode working surface size of the spot welding machine, which have a significant impact on welding quality.

　　 The above are the welding steps provided by Zhongbang Welding Machine for the majority of welding workers. If you want to know more about the spot welding machine, please pay close attention to Zhongbang Welding Machine.
