Welding robots are industrial robots engaged in welding activities (including cutting and spraying). According to the ISO industrial robot standard definition, an industrial robot is a multipurpose, programmable automated manipulator with three or more programmable axes, used in industrial automation. For welding automation, the system combines robots and positioners or flat worktables to design workstations, ensuring the position of the weld seam for good welding consistency and efficiency. The power source employs a microcomputer waveform-controlled inverter welding machine, offering stable arcs, minimal spatter, attractive appearance, and excellent welding performance.
