Orbital welding device with improved security and reduced failure probability

An orbital welding device, comprising:

• a weld head having a tubular mount and a welding electrode holder mounted rotatably with respect to the tubular mount;
• a motor controller;
• an electric motor, which is activated by the motor controller and is configured to drive the welding electrode holder to turn the welding electrode holder with respect to the tubular mount;
• and
• an electrical torque measuring device configured to measure a torque applied to the welding electrode holder by the electric motor, wherein the electrical torque measuring device is connected to the motor controller, and the motor controller is configured to, in response to the measured torque exceeding a predetermined first torque for at least a predetermined threshold time period, do one or more of:
• output at least one of a visual signal, an acoustic signal, or a haptic signal;
• send an electrical signal for at least one of visual output, acoustic output, or haptic output on another device;
• or
• store an indication on a storage unit.
