At present, industrial manufacturing is relatively mature and is developing towards a more advanced stage--industrial 4.0. The industrial 4.0 level represents fully automated production, that is, intelligent manufacturing. The automobile industry is very developed in China. If the industry is divided from 1.0 to 4.0, the automobile industry is between 2.0 and 3.0, and individual new production lines can reach the 3.5. The purpose of intelligent automobile manufacturing is very clear, which is to reduce energy consumption, improve quality and efficiency, realize lean production as a whole to promote the overall manufacturing level.
With the rapid development of modern material, people gradually have requirements for comfort and aesthetics on automobiles. Traditional welding methods are low in precision, easy to deform, and slow in speed, making it difficult to adapt to the development trend of modern automobile intelligent manufacturing. Laser welding technology uses high-energy-density laser beams as the heat source. This is a welding technology with high precision and high welding efficiency. It is in line with the trend of modern automobile manufacturing and is becoming more and more popular in the industry.
Automobile manufacturing is the assembly of pre-made parts by welding or riveting. Laser welding technology can effectively reduce the number of solder joints. Under the premise of ensuring quality, it can reduce the use of materials, reduce overall weight, and save cost.
Laser welding can achieve computer or digital control, high welding accuracy, fast welding speed, welding speed is 3 to 5 times faster than traditional welding, which can significantly improve welding efficiency and improve overall manufacturing efficiency.
The laser can perform small-scale local processing, small heat-affected area, and can be precision welded. The surface of the welded product is smooth and tidy, and the overall texture is good. It can be used without post-processing.
Laser welding technology belongs to non-contact welding. The welding method is different from traditional welding. There is no need to use electrodes. It has very little impact on the loss and deformation of the machine. It can greatly reduce the heat input and reduce the incidence of adverse effects due to heat conduction. .
Two different materials can be welded. Common metal materials on the market can be freely combined and welded. Angles that are difficult to achieve manually can be automatically welded with a robotic arm. The welding does not need a vacuum environment and can be welded in a normal environment.
With the expansion of the global automotive market demand, while the automotive manufacturing process is accelerating, advanced manufacturing technologies represented by laser technology are also constantly promoting the upgrading of the automotive manufacturing industry. Laser welding machine technology can help automobile manufacturers improve the quality of welding interfaces, reduce accidents and accident losses caused by joint problems, and help companies achieve cost reduction, efficiency increase, and flexible response to market changes.
With the development of laser application technology, laser welding technology is widely used in many fields such as consumer electronics, packaging, shipping, aerospace, etc., especially in the field of automobile manufacturing, such as automobile door welding, roof, side frames, parts and other applications.
