The difference between laser spot welding machine and traditional welding technology

When using traditional welding technology, the metal material is generally required to be thicker than 0.2mm, otherwise it will be very easy to melt the metal. While using a jewelry laser welding machine to weld the metal material can be thinned to 0.1mm, which is suitable for processing thin and light electroforming shapes. products are particularly important. Since there is no need for multiple weldings in laser welding, there is no need to use fluxes with different melting points during multiple weldings, thus ensuring the quality of the jewelry.

The main welding advantages of jewelry laser welding machine:
1) When inlaying jewelry, position it accurately so that the surrounding inlaid jewelry will not be damaged during the welding process. The solder joints are fine and beautiful without excessive post-weld processing.

2) Laser spot welding parameters can be adjusted within a wide range, and the size of the welding spot during the welding process can be adjusted at will to achieve a variety of welding effects.

3) Fast processing speed, small thermal deformation and heat-affected zone.

4) The solder joints of laser welding are very small and have the same color as the non-welded areas. This is compared with the black circle that is just a black circle after ordinary welding. The appearance is not comparable.

In traditional welding, it is very troublesome to repair jewelry inlaid with gemstones. It requires both welding and taking into account the safety of precious gemstones, which is often time-consuming and labor-intensive. Welding with a jewelry laser welding machine is much more convenient. Since the laser beam can be focused to obtain a small spot, the welding positioning is very precise. Even small prongs will not be damaged during repair. And the heat is concentrated locally, and the workpiece will not produce an annealing effect, thus not affecting the overall strength of the workpiece.
