Spot welding is a very important step in the battery production process. Whether it is a single cell or a battery pack, positive and negative poles, tabs, etc., a spot welder is required.Spot welding machine also has many different type，here are the introduction of them：

1. Pulse cell spot welding machine：most used in the battery lab research，it can used for welding (single pin welding) of the negative electrode shell and the tab of the cylindrical battery.

2.Metal ultrasonic spot welding machine：Ultrasonic spot welding metal tabs，common to the winding and welding a metal lamination process，it can used for cylindrical battery cell and pouch cell.

3.Gantry spot welding machine for battery pack: Its manual operation, suitable for battery pack spot welding and assembly in the factory. This machine can assembling batteries like 18650, 26650, 21700... and Nickel or Nickel-Plated Steel strips.

4. Single side/double sided automatic spot welding machine: its suitable for battery pack single side or double-sided spot welding and assembly in the factory for  14500 / 18650 / 21700 / 26650 / 32700 etc. multi-parallel multi-series combination.

5.Laser welding machine: Used for battery pack welding, the workbench configuration is mainly composed of a laser generator, an automatic motion mechanical structure and an electrical system.
