(1) Stabilize and improve welding quality to ensure uniformity. 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 worker operation skills, thus ensuring stable welding quality. However, during manual welding, welding speed, dry elongation, and other factors vary, making it difficult to achieve uniformity in quality.

(2) Improved the working conditions of workers. When using robot welding, workers are only used to load and unload workpieces, away from welding arc light, smoke, and splashes.

(3) Improve labor productivity. Robots have no fatigue and can produce continuously for 24 hours. 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 makes it easy to control product output. The production cycle of robots is fixed, so the production plan is very clear.

(5) It can shorten the product replacement cycle and reduce the corresponding equipment investment. It can achieve welding automation for small batch products. The difference between robots and specialized machines is that they can adapt to the production of different workpieces by modifying the program.
