Welding robots are robotic systems that are designed to automate the welding process. They consist of a robotic arm, a power source, a welding torch, and a controller. The robotic arm is programmed to move the welding torch in a predetermined pattern, while the power source provides the necessary current for the welding process. The controller determines the speed, angle, and intensity of the welding arc, as well as the amount of material to be melted. Welding robots are used in a variety of industrial applications to increase productivity and reduce costs.
