3000w Raytools BG03S Galvo Laser Welding Head
Description
The BG03S is a high-precision galvo-type laser welding head designed for remote scanning welding applications under 3000W laser power. Utilizing a standard XY2-100 digital galvanometer interface and high-accuracy galvo motors, it allows for fully customizable weld paths on a flat surface—perfect for high-reflectivity materials that require consistent and precise welds.
Its wide scan area and fast welding speed make it ideal for large-scale, high-efficiency production. The BG03S can be expanded with CCD monitoring, visual positioning, and temperature control functions, making it especially suited for new energy battery manufacturing and similar precision industries.
