Application of welding robots in automobile production

Welding robots are currently widely used in the automobile manufacturing industry, such as welding of automobile chassis, seat frames, guide rails, mufflers and torque converters, especially in the welding production of automobile chassis. Toyota has decided to equip all its spot welding robots in Japan and overseas with spot welding as standard. This technology can improve welding quality, so it is even trying to use it to replace some arc welding operations. The movement time within a short distance is also greatly shortened. The company recently launched a low-height spot welding robot to weld the lower body parts. This short spot welding robot can also be assembled with a taller robot to process the upper part of the car body together, thereby shortening the length of the entire welding production line. Most of the domestically produced Santana, Passat, Buick, Sail, Polo and other car chassis parts such as rear axles, subframes, rocker arms, suspensions, shock absorbers, etc. are stress-bearing safety parts mainly using MIG welding technology. The main components are stamped and welded, with an average plate thickness of 1.5 to 4 mm. The welding is mainly in the form of lap joints and corner joints. The welding quality requirements are quite high, and its quality directly affects the safety performance of the car. After the application of robot welding, the appearance and internal quality of the welded parts have been greatly improved, and the stability of quality has been ensured, the labor intensity has been reduced, and the working environment has been improved.
