As we all know, laser welding machine technology is a welding method with "double high" welding accuracy and efficiency, and has many advantages. Nowadays, laser welding machines have been widely used in automobile manufacturing. Today, Leapion Laser shares the application of laser welding machines in automobile manufacturing.
With the continuous development of the automobile industry, higher requirements are put forward for the quality of the car body and the processing method of the car. After the laser welding machine is used in the automobile manufacturing industry, the production efficiency of automobiles has been significantly improved, and the quality of automobiles has also achieved breakthroughs.
The use of unequal thickness laser welded blanks in car body manufacturing can reduce the weight of the car body, reduce the number of parts, improve safety and reliability, and reduce production costs;
In-line laser welding in the automotive industry is used extensively in the assembly and connection of body stamping parts. The main applications include laser welding of roof cover, laser welding of trunk lid and laser welding of frame;
Another important body laser welding application is the laser welding of body structural parts (including doors, body side frames and pillars, etc.).
The reason for using laser welding is to improve the strength of the body and to solve the difficult problem of conventional resistance spot welding in some parts.
For example: welding of gears and transmission parts. In addition, various parts of the gearbox can be welded on this equipment, especially the differential case and drive shaft in the car gearbox, which are often joined and welded after the production of a single part. made.
When the car is driving, due to the bumps and squeezing of the ground, every component and structure is subjected to different degrees of impact, which requires a high precision and strength of the overall structure of the car.
Using the current laser welding technology, its dynamic and static stiffness can be improved by more than 50% compared with other welding processes, which reduces the noise and vibration during driving, improves the ride comfort, and also improves the safety performance of the car.
1. The production cycle is short, because the laser welding machine is controlled by the program settings of the computer, the positioning is accurate, the welding speed is fast, and several meters of materials can be welded in one minute. The accurate positioning of the machine works quickly, which improves the overall production efficiency.
2. The cost is reduced. The materials processed by laser welding technology basically do not have defects such as inability to penetrate and material deformation, less material loss, high fault tolerance, and no waste of manufacturing raw materials.
3. The welding quality is good. The laser welding technology uses the energy density laser beam as a heat source to weld a small area. The welded sheet metal materials are fully fitted, the surface of the body is smooth and neat, and the overall appearance is beautiful and textured.
4. There are many types of welding materials. Laser welding technology can weld materials of different thicknesses, types and grades together to make parts of various shapes, which greatly improves the flexibility of automobile design.
