(1) Stabilize and improve welding quality to ensure uniformity. Welding parameters such as welding current, voltage, welding speed, and welding elongation determine the welding result. When using robots for welding, the welding parameters of each weld remain unchanged, and the welding quality is less affected by human factors, reducing the requirements for worker operation skills and ensuring stable welding quality. In the case of manual welding, both the welding speed and dry elongation change, making it difficult to achieve uniformity in quality.

(2) Improve the working conditions of workers. During robot welding, workers are only used for loading and unloading workpieces, keeping away from welding arcs, smoke, and splashes. For spot welding, workers no longer carry heavy manual welding tongs, freeing them from high-intensity manual labor.

(3) Improve labor productivity. Robots are not tired and can produce 24 hours a day without interruption. In addition, with the application of high-speed and efficient welding technology, the use of robot welding has led to increasingly significant efficiency improvements.

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