Cheap 4-In-1 Water-Cooled Handheld Laser Welding Machine for Sale

The 4-in-1 water-cooled handheld laser welding machine integrates a laser generator, welding system, laser welding gun, and high-efficiency cooling system into one unit. It employs advanced fiber laser technology to achieve high-precision welding by near-infrared laser beams. Laser welding is a thermal fusion welding process where the workpiece surface is precisely heated by laser radiation, with heat rapidly conducting to the interior to form a uniform molten pool. Users can flexibly adjust parameters such as laser pulse width, energy, peak power, and repetition frequency to precisely control the welding effect. After the laser beam is removed, the molten pool quickly cools and solidifies, forming a strong and aesthetically pleasing weld seam.

This device is specifically designed for welding thin-walled materials and high-speed welding applications. It supports fine adjustments to weld seam width, depth-to-width ratio, and heat-affected zone, enabling functions such as welding, cutting, cleaning, and weld seam finishing for metal materials to meet diverse industrial needs. The equipped water-cooling system ensures high-performance output while enhancing stability during prolonged operation. Its portable design facilitates mobility, and when paired with the handheld laser welding head, it allows for more flexible workpiece processing.
