Laser welding machine has been researched since the birth of lasers in the 1960s. It has experienced nearly 40 years of development from the welding of thin small parts or devices to the current large-scale application of high-power laser welding in industrial production. It was clearly studied in the early 20th century. The first laser was developed in 1960. Four years later, the world’s first YAG solid-state laser and CO2 gas laser were developed. Since then, laser welding machines have been widely used in various kinds of industries.
1.The advantages of laser welding machine compared with traditional welding methods
① Before the advent of laser welding, the industrial industry has been using traditional welding methods. Due to the uneven local heating and cooling of the weldment, post-weld deformation often occurs, thus failing to meet the welding requirements, and because the welding is not precise enough, There will also be incomplete fusion between the workpiece and the weld metal or the weld layer, and the weld contains non-metallic slag, which absorbs gas and generates pores and other defects, which often cause the welded parts to crack and affect the sealing performance.
② Laser welding has the advantages of high energy density, small deformation, narrow heat-affected zone, high welding speed, easy automatic control, and no follow-up processing. In recent years, it has become an important means of metal material processing and manufacturing. More and more widely used in automobile, aerospace, defense industry, shipbuilding, marine engineering, nuclear power equipment and other fields, the materials involved cover almost all metal materials.
③ Although compared with traditional welding methods, laser welding still has the problems of expensive equipment, large one-time investment and high technical requirements, which makes the industrial application of laser welding in my country quite limited, but laser welding has high production efficiency and is easy to realize automatic Controlled features make it ideal for mass production lines and flexible manufacturing.
④ At present, metal welding has higher and higher requirements for welding strength and appearance. The traditional welding method will inevitably cause problems such as distortion and deformation of the workpiece due to its great heat input. In order to make up for the deformation problem, a large number of follow-up measures are required, resulting in an increase in cost. The fully automatic laser welding method has the smallest heat input and extremely small heat affected zone, which significantly improves the quality of the welded workpiece, reduces the follow-up work cost, and greatly improves the welding efficiency and stability.
2.Different models, a variety of options
In summary, the current laser welding technology is very mature. Laser welding machines have low energy consumption, high precision, and little environmental pollution. More and more technology industries are choosing laser welding machines to ensure product quality and reassure companies and customers.
