Laser welding has the advantages of high accuracy, cleanliness and environmental protection, various types of processed materials, high efficiency, etc. It is widely used in high-end precision manufacturing fields such as the automobile industry. Today we will introduce the automotive industry laser welding process applications.
Laser welding in the automotive industry manufacturing process mainly includes three major types of applications: body assembly and sub-assembly laser group welding, laser welding of unequal thickness plate, laser welding of automotive parts.
Automotive industry laser welding process applications
Body laser welding is mainly divided into assembly welding, side and roof welding, follow-up welding, the use of laser welding in the automotive industry on the one hand, can reduce the weight of the car, enhance the mobility of the car, while reducing fuel consumption; on the other hand, to enhance the quality of the product and technological sophistication.
Laser welding is in the body design and manufacturing, according to the different design and performance requirements of the body, will be different thickness, different materials, different or the same performance of the plate through the laser cutting and assembling technology connected to a whole, and then by stamping molding for a part of the body. At present, laser welding plate has been widely used in various parts of the automobile body, such as luggage compartment reinforcement plate, luggage compartment plate, shock absorber support, rear wheel cover, side panels, door panels, front floor, front longitudinal beams, bumpers, beams, wheel cover, B-pillar connectors, center column and so on.
Laser welding of automotive parts has the advantages of almost no deformation of the welded parts, fast welding speed, and no need for post-weld heat treatment. At present, laser welding is widely used in the manufacture of transmission gears, valve tappets, door hinges, drive shafts, steering shafts, engine exhausts, clutches, supercharger axles and chassis and other automotive parts.
Handheld laser welding machine adopts the original imported industrial robot, high positioning accuracy, large processing range, six-axis linkage, to realize the welding of automotive three-dimensional parts.
Manipulate the robot arm through the handheld terminal, the whole machine has a compact structure, even in the place with harsh conditions and many restrictions, it can still realize efficient operation.
Equipped with non-contact welding seam tracking system to detect and correct the deviation of welding seam in real time to ensure the welding quality.
According to the customer's working conditions, the design of reasonable safety protection devices, effectively prevent the welding process of laser radiation on the personnel injury.
Multiple stations can be designed to work together and take turns loading and unloading; highly flexible welding system, which can realize automatic control and long-distance welding, and improve the efficiency of automobile welding.
