The principle of 18650 lithium battery spot welding machine is to combine the welding parts, apply pressure through electrodes, and the resistance generated by the welding method and the resistance generated by the contact surface of the joint and the adjacent area is called resistance welding. Resistance welding has the characteristics of high production efficiency, low cost, lithium battery polishing assembly processing equipment, material saving, and easy automation. Therefore, it is widely used in aviation, aerospace, energy, electronics, automobiles, light industry and other industrial fields. It is one of the important welding processes.
Spot welding is a high-speed, economical connection method. It is suitable for manufacturing sheet metal parts that can be overlapped, do not require air tightness, and whose thickness is less than 3mm. It is to weld weldments on various points on the contact surface of the joint. Spot welding requires the gold to have good plasticity. The surface of the weldment is cleaned first, and then the welding plate is assembled and assembled, pressed between the two cylindrical copper electrodes, and pressed with pressure p. When the current is large enough, a large amount of current is generated at the contact of the board. Resistance heat will be the highest temperature gold
