Description

Technical Field

[0001] The present invention relates to the technical field of laser welding equipment, and in particular to a laser welding device for processing a tent bracket. Background Art

[0002] Laser welding machines, also commonly known as laser welders or laser welding machines, are machines used for laser welding in material processing. Laser welding utilizes high-energy laser pulses to locally heat a small area of ​​the material. The energy from the laser radiation diffuses into the material through heat conduction, melting the material to form a specific molten pool. It is a new welding method, primarily designed for welding thin-walled materials and precision parts. It can perform spot welding, butt welding, lap welding, and seal welding. It features a high aspect ratio, a small weld width, a small heat-affected zone, minimal deformation, fast welding speeds, and smooth, aesthetically pleasing welds. Post-weld treatment requires minimal or no treatment. The weld quality is high, free of pores, can be precisely controlled, has a small focused spot, high positioning accuracy, and is easily automated.

[0003] Tents, also known as tents, aluminum alloy greenhouses, are a kind of movable buildings. Tents mainly provide temporary tents for various activities such as industrial warehousing, logistics distribution, wedding banquets, outdoor exhibitions, sports events, tourism and leisure, business gatherings, celebrations, business promotion, military applications and disaster relief.
