The laser welding machine uses a high-energy laser beam to act on the metal surface, the laser energy is diffused into the material through thermal conduction, and the material is melted to form a specific molten pool. It is a new type of welding method, mainly used for the welding of thin-walled materials and precision parts. Laser welding has high aspect ratio, small weld width, small heat affected zone, small deformation, fast welding speed, smooth and beautiful weld, no post-weld treatment or simple processing, high weld quality, no pores, precise control, and small focus , high positioning accuracy, easy to achieve automation.

Because laser welding machines have a series of advantages, laser welding equipment has gradually penetrated into our lives and has been used more and more widely, especially in many industries, gradually replacing traditional welding methods.

The industrial application of laser welding machine involves the following industries:

Sanitary ware industry: Welding of water pipe joints, reducers, tees, valves and showers.

Glasses industry: precision welding of stainless steel, titanium alloy and other materials for the buckle and outer frame of glasses.

Hardware industry: Welding of impellers, kettles, handles, etc., complex stampings and castings.

Automotive industry: engine cylinder gasket, hydraulic tappet seal welding, spark plug welding, filter welding, etc.

Medical industry: welding of medical devices, stainless steel seals and structural parts of medical devices.

Electronic industry: sealing and breaking welding of solid state relays, welding of connectors and connectors, welding of metal shells and structural components such as mobile phones and MP3. Motor housings and connectors, welding of fiber optic connectors, household hardware, kitchenware and bathrooms, stainless steel door handles, electronic components, sensors, clocks, precision machinery, communications, handicrafts and other industries, automotive hydraulic tappets and other industries have high strength The product.

Almost all of these industries use laser welding equipment. The advantages of laser welding machines are concentrated energy, no pollution, small solder joints, wide range of weldable materials, strong applicability, high efficiency, and high-speed welding. At the same time, products with the following requirements are also suitable for laser welding.

1. Products with welding requirements. Products that require welds are welded with laser welding equipment that not only has small welds, but also requires no solder.

2. Highly automated products. In this case, the laser welding equipment can be manually programmed to weld and the path is automatic.

3. Products at room temperature or under special conditions. It can stop welding at room temperature or special conditions, and the laser welding equipment is easy to install. For example, when a laser passes through an electromagnetic field, the beam is not deflected. Lasers can weld in vacuum, air, and certain gas environments, and can pass through glass or materials that are transparent to the beam to stop welding.

4. Some inaccessible parts require laser welding equipment. It can weld hard-to-reach parts and enable non-contact remote welding with high sensitivity. Especially in recent years, under the condition that YAG laser and fiber laser technology are very mature, laser welding technology has been widely promoted and applied.
