Zusammenfassung:	A welding arrangement ( 5, 23 ) for welding pipe sections ( 6, 7 ) comprises a power supplying and gas supplying unit ( 7, 24 ), a welding unit operatively connected to the power supplying and gas supplying unit and adapted at least in part to displace about the circumference of the pipe ( 6, 7 ) during the welding operation, and means whereby the power and gas are transmitted to the welding unit through a transmitting ring ( 8, 27 ) sufficient in diameter to extend around the pipe ( 6, 7 ) during the welding operation and thereby enabling the power and gas supply unit ( 7, 24 ) to remain stationary during the welding operation.
