Product introduction:
The Laser Jewelry Spot Welding Machine is mainly used for hole repairing, sand hole welding, and precision restoration of gold and silver jewelry. As one of the key applications of laser material processing technology, laser spot welding is a heat conduction-based process—the laser beam irradiates and heats the workpiece surface, and the heat diffuses inward through conduction. By precisely controlling parameters such as laser pulse width, energy, peak power, and repetition frequency, the material locally melts to form a stable molten pool and achieve firm, precise welds.
With its high welding precision, minimal heat-affected zone, smooth and aesthetic weld seams, and user-friendly operation, the machine is widely used in gold and silver jewelry manufacturing, precision electronics, micro components, and fine repair applications, providing an efficient and reliable solution for high-end jewelry fabrication and micro welding industries.

Key Advantages:
1. Imported ceramic condenser cavity with excellent corrosion and high-temperature resistance, offering high photoelectric conversion efficiency and an extended service life.
2. Adjustable laser energy, pulse width, and frequency, making it suitable for precise welding of various metal materials.
3. Ergonomic design ensures long-term operation without fatigue, while the specialized inner cavity allows convenient recovery of precious metals.
4. High speed and efficiency, featuring minimal deformation, a small heat-affected zone, superior welding quality, and eco-friendly, pollution-free performance.
5. Equipped with a crosshair positioning system and a high-speed LCD light valve automatic shading mechanism, which works in synchronization with the protective gas to ensure clean, oxidation-free, and aesthetically perfect weld joints.
Applications:
This machine is mainly used for filling holes and spot welding sand holes in gold and silver jewelry. It is also widely applied to the spot welding of micro and small precision components in industries such as jewelry, watches, eyewear, and dental prosthetics, providing high precision, stability, and refined welding performance.
