Welding robot mainly includes robot and welding equipment. The robot consists of a robot body and a control cabinet (hardware and software). The welding equipment, for example, arc welding and spot welding, is composed of welding power source (including its control system), wire feeder (arc welding), welding gun (clamp) and other parts. There should also be a sensor system for intelligent robots, such as laser or camera sensors and their control devices.

• Stabilize and improve the welding quality, which can reflect the welding quality in numerical form;
• Improve labor productivity;
• Improve the labor intensity of workers and work in harmful environments;
• Reduced the requirements for workers' operation technology;
• Shorten the preparation period for product retrofitting and reduce the corresponding equipment investment.
