The reason why welding robots account for more than 40% of all industrial robots is related to welding. Due to welding fumes, electric arcs and metal spatter, welding as an industrial "tailor" is a very important processing method in industrial production. The welding environment is very bad, and the quality of welding has a decisive influence on product quality. In short, the use of welding robots has the following main meanings:

　　(1) Stabilize and improve the quality of welds, and ensure uniform welds. Welding parameters such as welding current, voltage, welding speed and welding dry elongation determine the welding result. When robot welding is used, the welding parameters of each weld are unchanged, the welding quality is less affected by human factors, the requirements for the worker's operating skills are reduced, and the welding quality is stable. In the case of manual welding, the welding speed and dry elongation are changed, so it is difficult to achieve quality uniformity.

　　(2) Change the working conditions of workers. Robot welders are only used to load and unload workpieces, away from welding arcs, fumes and splashes. For spot welding, workers no longer carry heavy manual welding tongs, freeing workers from intensive manual labor.

　　(3) Improve labor productivity. The robot is not fatigued and can produce 24 hours a day. In addition, with the application of high-efficiency welding technology, robot welding is used, and the efficiency is more obvious.

　　(4) The product cycle is clear and it is easy to control the output of the product. The production cycle of the robot is fixed, so the production plan is very clear.
