Laser welding has the advantages of high accuracy, cleanliness and environmental friendliness, various types of processed materials and high efficiency, and is widely used in the automotive industry and other high-end precision manufacturing fields. Today we will introduce the application of laser welding processes in the automotive industry.
The application of laser welding in the manufacturing process of the automotive industry includes three main types: laser assembly welding of body assemblies and sub-assemblies, laser assembly welding of unequal thickness plates and laser welding of automotive components.
Laser welding of the body is mainly divided into assembly welding, welding of the side and top cover and follow-up welding. The use of laser welding in the automotive industry can, on the one hand, reduce the weight of the car, improve its mobility and at the same time reduce fuel consumption; on the other hand, improve the quality and technical advancement of the product.
Laser welding is a process whereby sheets of different thicknesses, materials and properties are joined into a whole by laser cutting and assembling technology and then stamped and formed into a body part according to the different design and performance requirements of the body. At present, laser welded panels are widely used on various parts of car bodies, such as luggage compartment reinforcement panels, inner luggage compartment panels, shock absorber mounts, rear wheel covers, inner side panels, inner door panels, front floors, front longitudinal beams, bumpers, cross beams, wheel covers, B-pillar connectors, centre pillars, etc.
Laser welding of automotive parts has the advantages of almost no deformation in the welded area, fast welding speed and no need for post-weld heat treatment. Laser welding is currently used in the manufacture of automotive components such as transmission gears, valve tappets, door hinges, drive shafts, steering shafts, engine exhaust pipes, clutches, supercharger axles and chassis.
Industrial robot with fibre laser welding machine with high positioning accuracy, large processing range and six-axis linkage for the welding of three-dimensional automotive parts.
The robot arm is controlled via a handheld terminal and the whole machine is compact, allowing for efficient operation even in locations with harsh conditions and considerable restrictions.
It can also be designed for multiple stations to work together and take turns to load and unload; a highly flexible welding system that enables automatic control and long-distance welding to improve the efficiency of automotive welding.
