Laser Welder for Solar System

Solar panels laser welding machine. The product is a new fiber optic laser welding machine which is adapt to solar system's rapid development of industry and market development . Specially for welding Copper - Aluminum, Copper-copper solar panel, this is a national initiative, has been applied for patents of inventions. It consists of lasers, laser power, optical systems, optical transmission systems, refrigeration systems, CNC control system, and some other composition. With the use of two optical transmission, the welding technology is not only flexible, and to reduce the damage to a large extent on the surface coating, not causing the sheet-metal heat deformation by open methods of work, easy leading to the automation of the upper and lower links processes.
