With the continuous maturity of laser application technology, the application and utilization of lasers are becoming more and more convenient, and are widely used in many fields such as electronic consumer goods, packaging, ships, aerospace, automobile manufacturing, etc. , giving us a qualitative leap in the quality of our current products and creating more comfortable products and services for people’s lives. Today, laser welding technology has been widely used in the current automobile manufacturing field, injecting new vitality into the current automobile processing, and has become an important method of current automobile processing.
Welding applications in the automotive industry
The welding application of laser welding machine in automobile body:
1. Laser welding is used for the welding of the roof shell and the frame, and the welding of the cover plate of the transmission converter, which is controlled by CNC. The cycle time is about 16 seconds, the actual welding time is only 3 seconds, and it can run continuously for 24 hours a day. Used to weld the gearbox assembly and chassis of the car, the welding speed of the laser beam is fast, easy to automate control and easy to incorporate into a flexible manufacturing system, the laser beam improves the manufacturer’s product design and production cycle and reduces the waste of finished products. Rate.
2. The application of laser welding in the automobile industry The use of laser welding can bring huge economic benefits to the automobile manufacturing industry, such as a large number of spot welding in the body assembly, the two welding heads are clamped on the edge of the workpiece for welding, and the width of the flange It needs 16mm, and laser welding is unilateral welding, only 5mm is needed, the spot welding should be laser welding, and each vehicle can save 40kg of steel. Two 0.8mm steel stampings are welded by traditional spot welding, with an average of 20 points/min and a welding distance of 25mm, that is, the speed is 0.5m/min, and the speed of laser welding can reach more than 5m/min. The use of laser welding technology not only reduces costs, but also greatly improves production efficiency.
3. It is used for the cutting of automobile metal parts and the welding of gears, which shortens the modification of automobiles from 5 years to 2 years. General Motors of the United States has adopted 22 laser processing production lines. Ford Motor Company of the United States has used Nd:YAG lasers combined with industrial robots to weld car bodies, which has greatly reduced manufacturing costs. In 2000, the three major American automobile companies already had 50% of the resistance points Welding lines were replaced by laser welding lines. In Japan, the successful application of laser welding on production lines has attracted worldwide attention. For example, in the manufacture of automobile bodies, a new method of stamping and forming thin steel sheets after laser welding has been imitated by most automobile manufacturers in the
Gantry laser welding equipment
Prospects of Laser Welding Technology Laser welding technology has had an impact on the traditional automobile welding process. Major automobile companies have a very positive attitude towards this. The adoption of new technologies means stronger competitiveness, especially competition. brutal car industry. Laser welding technology has the greatest application prospects in welding aluminum materials, replacing castings with welded parts, and welding the whole body frame structure. Make the laser more suitable for the needs of the automobile production line. Traditional processing technology cannot meet the needs of new production methods, which provides an opportunity for the large-scale application of laser welding technology. Laser welding technology and other laser processing technologies will definitely have greater development in the automotive field and become an important part of the automotive industry. processing method.
