Principle of laser spot welding machine

Using high-energy laser pulses for local heating

The working principle of laser spot welding machine is to use high-energy laser pulses to locally heat the material in small areas. The energy radiated by the laser is guided to the interior of the material through thermal conduction, melting the material and forming a specific molten pool, thus achieving welding. This welding method is suitable for thin-walled materials and precision parts, and has the characteristics of small weld width, small heat affected zone, fast welding speed, and smooth and beautiful weld seam. ‌

The main components of a laser spot welding machine include the laser, power supply, control, and cooling machine. The laser generates a high-energy laser beam, which is focused and directed onto the workpiece to melt the local material and form a weld seam. The power and control department is responsible for providing necessary power and support to ensure stable output and precise control of the laser beam. The cooling machine is used to maintain the stable operation of the laser and prevent overheating.

Laser spot welding machines are widely used in industry, mainly for welding small, heat sensitive parts such as jewelry, watch hairspring, and integrated circuit leads. Due to its high-quality welding effect and pore free characteristics, laser spot welding machines have significant advantages in the field of precision welding.
