With the market demand, the demand for efficient production equipment is increasing. As a high efficiency welding equipment, Laser Welding Machine has been used in more and more fields. The principle is that the laser beam penetrates the surface of the object to obtain high-quality melting effect. Laser welding machine is a process that heats materials through different power pulsed laser beams to melt materials and weld them. It can heat the material to the melting point or melting point in a short time, and the surface of the welded material is smooth and neat. Compared with traditional welding equipment, it has lower price, higher production efficiency and higher degree of automation, and is widely used in automobile, household appliances, furniture, aerospace and other industries.

1. Automobile industry
As a common welding method in the automobile industry, laser welding has become one of the important topics in welding technology research because of its good welding performance, high surface finish, high welding strength, uniform solder joints, good surface aesthetic performance, small welding deformation, good solder joint toughness, strong weld fatigue resistance, strong corrosion resistance, short welding time, and high welding quality. In addition, the mixing or superposition heating of laser beam and electron beam or other light sources can change the characteristics of metal surface, making it more closely and firmly combined with the workpiece. Therefore, laser welding can be widely used in the automotive industry for drilling, riveting, drilling and other processes. Laser welding requires high surface roughness, the welding surface must be flat without burrs, the welding effect is good, and the penetration depth is not less than 0.1 mm. The multiple laser beams used in automobile laser welding work on the same line at the same time, and can weld metal components of various colors and patterns, including axles, lamps and other accessories. At the same time, appropriate laser power, welding parameters and welding process can be selected according to different workpieces. By controlling the welding parameters, automatic welding can be realized without manual operation, which is convenient, fast, efficient, and of good quality – this hand-held laser welding machine is widely used in the automotive industry, such as instrument panel, instrument, air conditioner, lighting, audio and other parts, as well as in the welding of other automotive interior trim parts.
2. Household appliance industry
With the economic development, consumers’ demand for household appliances is getting higher and higher. In the past, due to the low level of welding technology and automation, only manual operation and manual welding could be used. With the improvement of welding technology and automation level, as well as people’s higher and higher requirements for products, the application field of welding machine is more and more extensive. Like Laser Marking Machine, hand-held laser welding machine is widely used in the welding process of various complex metal parts, various hardware products, plastic products and other products in the household appliance industry. In the production of household appliances, most of the small household appliances use copper and aluminum alloy as the main material of the shell, liner, internal structure and other metal parts. The traditional welding method is time-consuming and laborious and has large welding defects; The hand-held laser welding machine can easily solve the above problems, and the processing cost is lower. For example, the traditional welding of aluminum shell and liner usually requires welding the shell and liner before welding the shell, which is not only time-consuming and laborious, but also has large welding defects; The hand-held laser welding machine can complete the above process without welding the shell and tank in advance, and the production efficiency is greatly improved; In addition, the hand-held laser welding machine can also complete the functions of spot welding, punching, riveting, welding, grinding, spraying, etc. of multiple parts; Finally, the hand-held laser welding machine can also be used in the processing of electronic products, plastic products and other metal products (such as mobile phones, computers, etc.); It is also widely used in refrigerators, washing machines and other products.
3. Aerospace industry
The aerospace field requires high safety, so it has higher requirements for high strength and high toughness of materials. For the riveting process commonly used in the aerospace field, it needs to use high-speed laser to connect structures and complete the production of overall connection or combination. Laser thermal processing has the characteristics of small heat affected zone and fast heating speed, so it can meet the above requirements, such as the connection and parts processing of engines, fuselage, wings, wing bodies, fuselage components, rocket engines in aerospace. Handheld laser welding machine is also widely used in aerospace field. The hand-held laser welding machine is mainly used in the welding of aviation materials. For example, bolt riveting on aircraft, riveting of wing beam and other parts, welding of tail wing and other parts, welding on various aircraft, wing connection on various spacecraft, connection between various connectors, etc. can be conducted by hand-held laser welding machine.
