(1) Stabilize and improve the welding quality to ensure uniform welding. Welding parameters, such as welding current, voltage, welding speed, and welding dry - elongation, determine the welding results of the welding robot. When using robot welding, the welding parameters of each weld remain unchanged, and the welding quality is less affected by human factors, reducing the requirements for workers' operating skills and ensuring stable welding quality. In the case of manual welding, both the welding speed and the dry - elongation change, so it is difficult to achieve uniform quality.

(2) Improve the working conditions of workers. Workers only need to load and unload workpieces when using the robot welder, keeping them away from the arc, fumes, and spatter. For spot welding, workers no longer need to carry heavy manual welding tongs, thus freeing workers from heavy physical labor.

(3) Increase labor productivity. Robots do not get tired and can work 24 hours a day. In addition, with the application of welding technology, the efficiency of using robot welding is even more obvious.

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