Laser welding is the use of high-energy laser pulses to locally heat materials in small areas. The energy of laser radiation is diffused into the material through thermal conduction, and the material is melted to form a specific molten pool. It is a new type of welding method. Laser welding is mainly used for welding thin-walled materials and precision parts. It can realize spot welding, butt welding, overlay welding, seal welding, etc., with high aspect ratio, small weld width, and heat-affected zone. Small, small deformation, fast welding speed, flat and beautiful welding seam, no treatment or simple processing after welding, high welding seam quality, no pores, precise control, small spotlight, high positioning accuracy, easy to realize automation.

Laser welding machines are widely used, and there are many welding methods, such as spot welding, splicing welding, overlay welding, and sealing welding. The successful use of laser welding machines in splicing welding has brought huge economic benefits to the automotive and shipbuilding industries. 威廉希尔官方下载ing laser splicing to replace the spot welding process not only saves a lot of work time, reduces production costs, but also improves welding quality.

Splicing welding refers to the welding of several pieces of stainless steel, steel, aluminum, etc. of different materials, different thicknesses, and different coatings to form a whole, so as to meet the different requirements of parts and materials for different materials.

The welding principle of laser welding machine for splicing welding is: high-energy laser beam hits the edges of two parts to be welded, and the output energy heats and melts the metal. After the laser beam acts, the molten material quickly cools and becomes a whole. The advantages of laser splicing welding are fast welding speed, no filler, large penetration depth, small thermal deformation, and automatic welding. Another important feature of laser welding is that the laser beam can be focused to a few tenths of a millimeter, retaining the good forming ability of the material. The welding seam of laser splicing welding is narrow and flat, which is conducive to subsequent processing.

The application of laser splicing welding in the automotive industry can reduce the manufacturing cost of automobiles, reduce the weight of automobiles, reduce the number of peripheral reinforcements, simplify the assembly process, and improve the collision and stamping capabilities of vehicles. In the future, laser splicing welding will be applied in more fields.
