摘要
An orbital welding device (1) having a welding head (2), the welding head having a tubular mount (3) and a welding electrode holder (4) rotatably supported with respect to the tubular mount (3), the orbital welding device (1) having an electric motor (6) activated by a motor controller (5) of the orbital welding device (1), which is configured to drive the welding electrode holder (4) and thus to rotate the same with respect to the tubular mount (3), wherein the orbital welding device (1) has an electric torque measuring device (7), which is configured 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 wherein the motor controller (5) is configured to stop the motor (6) automatically if the torque exceeds a predetermined first torque.
