　　Laser welding equipment Application in sheet metal chassis planning and processing

The planning and processing of sheet metal chassis are relatively complex. During manufacturing, some metal sheets need to be deformed by tools to plan into the shape and scale required by customers. In this process, some parts need to be processed by welding and other methods to meet the planning objectives, then the welding process is particularly important.

The production process of modern sheet metal chassis and cabinet processing profession has developed rapidly. Most of the chassis and cabinet welding operations have strict welding requirements, such as welding slag, deformation, burn through, bulge and depression are not allowed. The welding requirements are regular, uniform, firm and reliable. Traditional argon arc welding can not keep up with the expanding market demand, nor can it meet the process requirements of customers for "beauty and quality" of products. Argon arc welding has slow speed, low power, large deformation and high labor cost, which is destined to be replaced by laser welding. Due to the rapid development of laser technology, laser welding has faster speed, higher power and small deformation, Low labor cost.

The data of chassis and cabinet include stainless steel, aluminum and copper. The thickness of general steel data is 1mm-3mm, the common thickness is 1.5mm, and the thickness of aluminum data is 2mm-3mm. The shell shall be a continuous metal body, which can generally be formed by continuous welding or casting of plates. The splicing of skeleton components shall not affect the connectivity of shell surface. These thickness data are particularly suitable for fiber laser welding, Fiber laser welding machine It is widely used in chassis and cabinet industry.

Optical fiber Laser welding machine Also called Optical fiber transmission laser welding machine, optical fiber transmission laser welding machine is a kind of laser welding equipment that couples high-energy laser beam into optical fiber, after long-distance transmission, it becomes parallel light after quasi diameter, and focuses on the workpiece for welding. For parts that are difficult to be accessed by welding, flexible transmission non touch welding has greater flexibility. The laser beam can realize the light splitting in time and energy, and can process multiple beams together, which provides conditions for more precise welding. It is suitable for welding most workpieces and has strong universality. It has been widely used in hardware and other occupations.
