Jewelry industry

Due to the high precision of laser processing, it is very suitable for precious small products in the jewelry industry. Because the laser focused beam is extremely thin, it can be enlarged through a microscope to enlarge the small part of the jewelry to achieve precise welding. The connection of the jewelry chain and the setting of the gemstones need to be done with a laser spot welder. Laser spot welding machine is a must-have equipment.

Building materials industry

Laser welding precision has good appearance, so it has a wide range of applications in laser marking and laser welding of high-end sanitary stainless steel products. Such as: handles, faucets, stainless steel tableware, knives, etc., laser marking is often used to make corporate LOGO, and the sealing of high-end electric kettles is also completed by laser welding.

Kitchenware industry

In the kitchenware industry, a large number of sheet metal parts need to be welded. For example: group welding and butt welding of kitchen utensils, repair and modification during mold making and use. Laser welding perfectly solves the two major problems of weld beauty and welding quality.

Lighting industry

In the lighting industry, due to the complexity of the shape and structure of the lighting, there are many hard-to-reach parts that cannot be welded by ordinary welding machines, and the effect after welding must be guaranteed. Handheld laser welding machines have exactly this function. The welding angle can be moved at will to achieve better welding effect and break the space limitation of traditional welding.

Mould and machinery manufacturing

The most typical example of the application of laser welding in the mold industry is the mold repair laser welding machine. Due to the obvious advantages of non-contact processing, laser processing is especially suitable for molds and high-precision machinery manufacturing industries, such as plastic molds, rubber molds, stamping molds, casting molds, etc. , Forging dies, precision repair of wire drawing dies.

This laser welding repair technology can not only be used to repair mold wear, but also achieve precise welding of small and precise areas without deformation and pores after repair.

What are the precautions for welding?

1. When operating, it should be segmented or staggered, so that the welding can be more stable, and at the same time, the degree of edge melting should be observed to avoid undercut or unfused. Because the construction materials and structures are different, it is necessary to use the equipment flexibly to carry out different operation methods to ensure the perfect fusion of the welds. When using the multi-layer and multi-pass method, it is necessary to control the swing of the welding torch and the amount of metal.

1. In order to prevent the cooling speed from falling too fast, it is necessary to control the temperature to prevent the occurrence of cracks, so that the stability of the structure cannot be increased. Then when the temperature is controlled, it should be carried out according to the material, not randomly increased or decreased, some materials must be carried out at high temperature, which requires precise temperature control during welding.

1. When the fusion is good, the heat input should be strictly controlled. At this time, a small current and a slow speed should be used to avoid fusion defects and make the material better welded. The same weld should be completed continuously, because if you do it again and again, the fusion will not be complete due to the cooling in the middle. In special cases, when it is necessary to preheat the welding again.
