Battery laser welding is to focus the laser beam on a small workpiece area through the optical system, and use its excellent directivity and high power density to process the workpiece to form a heat source area with highly concentrated energy in a very short time, thereby Make the workpiece melt and form firm welding spots and seams to complete the welding task.
The battery laser welding process has concentrated energy, high welding precision, high efficiency and firm welding. The laser beam is easy to focus, flexible and convenient, and can be redirected between fixtures or obstacles around the workpiece. The welding energy can be precisely controlled, the welding effect is stable, and the welding appearance is good.
There are many factors that affect the quality of laser welding. For example, some of these parameters are extremely volatile and prone to instability if used improperly.
How to correctly set and control these operating parameters so that they can be controlled at a reasonable threshold in the high-speed continuous laser welding process to ensure welding quality.
Battery laser welding requires connection processing on the edge of the battery workpiece, which requires high precision, and the light spot is strictly aligned with the weld seam. Moreover, the original assembly accuracy of the workpiece and the focus of the light spot cannot be changed due to welding heat transfer during the welding process.
