Penta Laser Pillow Plater Laser Welding Machine is a specialized laser welding machine tailored precisely for heat exchanger plate welding requirements. It supports automatic programming for various shapes and complex patterns, ensuring convenient and efficient operation. The active cooling workbench reduces plate deformation, while the main and auxiliary dual clamping devices ensure uniform and stable welding. The machine performs double-sided bulging of plates with single-sided welding and double-sided forming and ensures that the backside of single-sided bulged plates has no welding marks, producing aesthetically pleasing welds and reliable quality.
