Laser welding is an advanced welding technique widely used in high-end precision manufacturing fields such as the automotive industry. It offers advantages such as high precision, cleanliness, environmental friendliness, compatibility with various materials, and high efficiency. As an emerging welding method, laser welding technology has found extensive applications in the automotive industry.
In automotive manufacturing processes, laser welding is mainly applied in three areas: laser welding of body assemblies and sub-assemblies, laser welding of dissimilar thickness plates, and laser welding of automotive components.
Laser welding is extensively utilized in the body manufacturing process of the automotive industry, including the joining of components such as doors, roofs, and carriages. It provides high-quality welds and exhibits good adaptability to various materials, such as steel, aluminum, and others. Body laser welding primarily involves assembly welding, side member and roof welding, as well as subsequent welding processes. Adopting laser welding technology can reduce vehicle weight, enhance maneuverability, and decrease fuel consumption. Laser splicing welding, a common body design and manufacturing technique, involves using laser cutting and assembly techniques to connect plates of different thicknesses, materials, and performance characteristics. These plates are then stamped and formed into specific body components.
Laser spliced welding plates are widely used in various parts of automotive bodies, such as luggage compartment reinforcement plates, luggage compartment inner plates, shock absorber brackets, rear wheel covers, inner side panels, inner door panels, front floors, front longitudinal beams, bumpers, crossbeams, wheel arches, B-pillar connectors, and center pillars. The application of this technology enables lighter body structures while meeting the strength and stiffness requirements of different areas.
Laser welding has many advantages in the manufacturing of automotive components. It minimizes deformation at the welding site, offers fast welding speeds, and eliminates the need for post-weld heat treatment. Currently, laser welding is widely applied in the production of various automotive components, including transmission gears, valve pushrods, door hinges, drive shafts, steering shafts, engine exhaust pipes, clutches, turbocharger shafts, and chassis components.
To meet the demand for laser welding in the automotive industry, riselaser has developed a 6-axis robot fiber laser welding machine. This equipment utilizes imported industrial robots with high precision positioning capability and a wide processing range. Through six-axis coordination, it achieves the flexibility and freedom required for welding automotive components.
This system utilizes automation technology to achieve high precision and stability in welding, significantly reducing the need for direct human involvement and ensuring worker safety. Depending on the specific working conditions of the customers, reasonable safety protective measures can be designed to effectively prevent laser radiation hazards to personnel during the welding process. Additionally, the system is capable of multi-station collaborative work, enabling alternate loading and unloading, thus improving welding efficiency. Moreover, it is a highly flexible welding system that allows for automation control and remote welding, further enhancing the efficiency of automotive welding.
