Laser welding is the second largest laser processing application technology after laser cutting. In recent years, driven by the demand of new energy vehicles, semiconductors, power batteries and other emerging industries, the laser welding market has seen rapid growth. In this process, the major manufacturers and merchants have smelled new opportunities for future development. The layout of relevant upstream and downstream brands has been accelerated in this process, and the industry is gradually showing a scene of burning coals.
At present, hand-held laser welding equipment has begun to enter the workshops of major, small and medium-sized manufacturers, becoming a new outlet for laser welding. More new players want to know about the relevant technical parameters of laser welding, and we have also encountered many similar problems in the consultation process. Therefore, this article is intended to solve the problems for some users for reference.
laser power
Laser power is one of the main parameters of laser welding. Laser power determines the energy density of laser. For different materials, the threshold is different. The higher the laser power is, the better it is. For laser welding, the higher the laser power is, the material may be penetrated; However, too low power is not enough. If the power is not enough, the material penetration is not enough, and only the surface is melted, the required welding effect will not be achieved.

Laser focus
Focus adjustment, including focus size adjustment and focus position adjustment, is one of the main variables of laser welding. Under different processing environments and processing requirements, the required focus size is different for different welds and depths; The relative position change of the focus and the workpiece processing place directly affects the quality of welding. Generally speaking, the adjustment of focus data needs to be targeted in combination with the on-site situation.
