With the change of laser technology, sheet metal processing and welding technology can achieve more and more precise processes, and these precision sheet metal parts can be applied in high-precision fields such as automation, electric power, transportation, and medical treatment to promote the upgrading of the manufacturing industry.

The selection of materials for laser welding in sheet metal processing is very cautious. Generally, stronger materials are selected, mainly stainless steel, aluminum and copper. The thickness of ordinary steel is 1mm-3mm, the usual thickness is 1.5mm, and the thickness of aluminum is usually 2mm-3mm. . The shell is a continuous metal body, and can usually be formed by continuous welding or casting. The splicing of the frame parts should not affect the continuity of the shell surface. Materials of these thicknesses are particularly suitable for fiber laser welding. Therefore, fiber laser welding machines have also been widely used in the field of sheet metal chassis manufacturing.

Fiber transmission laser welding machine is a kind of laser welding equipment that couples a high-energy laser beam into an optical fiber. After long-distance transmission, it is collimated into parallel light by collimating the diameter and focusing on the sheet metal part. For parts that are difficult to weld, flexible transmission and non-contact welding have greater flexibility. The laser beam can realize the separation of time and energy, and can process multiple beams at the same time, which provides conditions for more precise welding. It is suitable for the welding of most sheet metal parts and has strong versatility. It has been widely used in hardware equipment and other industries.
