2. Introduction:

The high precision laser welding machine is a device that uses a high-energy density laser beam to precisely weld metal components. It achieves high-strength, low-deformation welding with advantages such as high welding accuracy, fast speed, and small heat-affected zones. It is particularly suitable for welding critical areas like busbars, terminals, and cell tabs in lithium battery module and pack production. Adopting advanced control systems and optical components, it meets high-standard, high-quality production requirements.

3. Working Process:

• Workpieces are placed on dedicated welding fixtures for precise positioning and fixation.

• Laser parameters such as power, frequency, and welding speed are set according to the material.

• The laser beam is delivered and focused through a fiber optic cable, precisely irradiating the welding area.

• The laser energy concentrates and melts the metal to form a weld pool, which solidifies into a weld seam upon cooling.

• A robot or motion platform controls the movement of the laser head to complete complex welding paths.

• An online monitoring system continuously monitors the welding process to ensure stable quality.
