Welding robots are industrial robots engaged in welding (including cutting and spraying). According to the International Organization for Standardization (ISO) standard for industrial robot terminology, an industrial robot is a multi-purpose, reprogrammable automatic control manipulator with three or more programmable axes used in the field of industrial automation. In order to adapt to different purposes, the mechanical interface of the last axis of the robot is usually a connecting flange that can accommodate different tools or end effectors. Welding robots are devices that attach welding tongs or welding (cutting) guns to the end flange of industrial robots, enabling them to perform welding, cutting, or thermal spraying.Fanuc Robot Welding
