Application of laser welding in jewelry industry
The application of laser welding machine in the arts and crafts jewelry industry has been exerted and embodied, mainly for precision necklaces and other jewelry. The application of laser welding machine and laser marking machine in the jewelry industry is constantly developing and deepening. Laser welding uses high energy to melt and fuse together instantly.
The principle of the jewelry laser welding machine is that the surface of the metal will undergo a series of changes under the action of the laser, and the surface will be heated by the laser and quickly conduct as deep. Under the condition of a certain laser power density, the surface will melt, partly at the laser power density When it is high, it is instantly vaporized, forming a molten pool on the surface of the workpiece. In the welding process, the workpiece is moved relative to the laser, so that the molten metal is accelerated along a certain angle, the heat transfer temperature of the liquid metal is rapidly reduced, and the liquid metal forms a weld.

Jewelry laser welding machine is mainly used for repairing holes, spot welding, and repair welding of gold and silver jewelry. Using laser deposition welding, with laser high thermal energy and concentrated fixed-point welding technology, surface heat is diffused internally through conduction, and the workpiece is melted to form a specific molten pool by controlling parameters such as the width, energy, peak power and repetition frequency of the laser pulse . Because of its unique advantages, it has been successfully used in the processing of gold and silver jewelry and the welding of micro and small parts.
Laser welding has the characteristics of high welding strength and speed, and low scrap rate, and is widely used in jewelry manufacturing. Compared with traditional welding technology, it has the following advantages:
1. Fast speed, high strength, small deformation, no need for correction and cleaning after welding;
2. Suitable for welding precision workpieces, which can ensure processing quality;
3. High assembly accuracy, which is helpful Develop new technology;
4. Good consistency and stability;
5. Can simplify the work of workpiece repair;
6. Environmental protection and pollution-free;
7. Save processing metal materials.
Because the jewelry industry has introduced laser welding technology, it has changed people's traditional jewelry design thinking. With the help of laser welding technology, some special jewelry styles can be made.
