摘要
An orbital welding apparatus (1) having a welding head (2), the welding head comprising a pipe holder (3) and a welding electrode holder (4) rotatably supported with respect to the pipe holder (3), the orbital welding apparatus (1) being driven by a motor controller (5) of the orbital welding apparatus (1) controlled electric motor (6) which is adapted to drive the welding electrode holder (4) and thus to rotate with respect to the pipe holder (3), wherein the orbital welding device (1) comprises an electrical torque measuring device (7) which is set up to measure a torque applied by the motor (6) to the welding electrode holder (4), wherein the torque measuring device (7) is connected to the motor controller (5), and that the motor controller (5) is arranged, the motor (6) automatically stopping when the torque exceeds a predetermined first torque.A method of operating an orbital weld ßvorrichtung.
