At present, laser welding equipment has penetrated into our lives and has been used more and more widely, especially in many industries, gradually replacing traditional welding methods. The industry application of laser welding machine involves the following industries: Sanitary ware industry: welding of water pipe joints, reducers, tees, valves and showers. Eyewear industry: precision welding of stainless steel, titanium alloy and other materials for the buckles and outer frames of glasses. Hardware industry: welding of impellers, kettles, handles, etc., complex stampings and castings. Automotive industry: engine cylinder gaskets, hydraulic tappet seal welding, spark plug welding, filter welding, etc. Medical industry: welding of medical equipment, stainless steel seals and structural parts of medical equipment. Electronic industry: sealing and breaking welding of solid-state relays, welding of connectors and connectors, welding of metal shells and structural parts such as mobile phones and MP3s. Motor housing and connectors, welding of optical fiber connector joints, etc. Household hardware, kitchenware and bathroom, stainless steel door handles, electronic components, sensors, clocks, precision machinery, communications, handicrafts and other industries, automotive hydraulic tappets and other industries have high strength products. Almost all of these industries use laser welding equipment. The advantages of laser welding machine are concentrated energy, no pollution, small welding spot, 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.
