Exploring the Application and Current Situation of Welding Robots in China


  The reason why welding robotic arms can account for over 40% of the total industrial automation production is related to the special industry of welding. Welding, as an industrial "tailor", is a very important tool in industrial production. It is also because of the presence of welding dust, arc light, and metal spatter, and the harsh working environment of welding. The quality of welding plays a decisive role in product quality. At present, multiple industries in China, such as hardware, automobiles, and motorcycles, need to rely on the application and production of rugged robots. Why are welding robots so popular? In summary, the use of welding robots has the following main significance:

  (1) Stabilize and improve welding quality, ensuring its uniformity. Welding parameters such as welding current, voltage, welding speed, and welding elongation play a decisive role in the welding results. When using robot welding, the welding parameters for each weld seam are constant, and the quality of the weld seam is less affected by human factors, reducing the requirements for workers' operating skills, so the welding quality is stable. However, during manual welding, the welding speed, dry elongation, and other factors are variable, making it difficult to achieve uniformity of quality. Dalian Industrial Robot

  (2) Improved working conditions for workers. The use of robot welding workers is only for loading and unloading workpieces, away from welding arcs, smoke, and splashes. For spot welding, workers no longer need to carry bulky manual welding tongs, freeing them from heavy physical labor.

  (3) Improve labor productivity. Robots have no fatigue and can produce continuously 24 hours a day. In addition, with the application of high-speed and efficient welding technology, the use of robots for welding has significantly improved efficiency.

  (4) Clear product cycle, easy to control product output. The production rhythm of robots is fixed, so the production plan is very clear.

  (5) It can shorten the cycle of product transformation and reduce the corresponding equipment investment. Can achieve welding automation for small batch products. The difference between a robot and a specialized machine is that it can adapt to the production of different workpieces by modifying the program.

  Application status of welding robots in China

  China developed industrial robots later than the United States and Japan, starting in the 1970s. After more than ten years of continuous efforts, with the organization and support of the country, the research on welding robots in China focuses on basic technology, control technology, and key components

  Significant progress has been made in terms of components and other aspects

  Zhan has entered the stage of commercialization, forming a series of spot welding and arc welding robot products that can achieve small-scale production.

  Welding robots are high-tech products that integrate mechatronics. Relying solely on the capabilities of enterprises is not enough. The government needs to provide certain policies and financial support to robot production enterprises and enterprises using domestic robot systems, in order to accelerate the development of domestic robots in China. As of 2020, the number of domestic industrial robot manufacturers has surged, and their applications in various industries have become increasingly widespread. It is believed that in the near future, domestic robot manufacturers can break away from relying on foreign technology.
