The laser soldering machines adopts a high-energy laser beam to focus precisely on the weld point, and realizes fast and stable welding through the interaction between the laser and the material. Laser soldering machine has the characteristics of fast welding speed, small heat-affected zone, beautiful and solid weld seam, especially suitable for precision welding of tiny parts. In the automobile manufacturing, electronic appliances, medical equipment and other fields, laser soldering machines play an important role in that product quality and performance improvement provides strong support.
