A device for correcting the position of a welding electrode relative to the joint of parts being welded and to keep in axial relationship the weld seam and the joint, while the seam width is adjusted at the same time. The device has two photoelectric sensors indicating the position of the joint and the seam, and follow-up and control units associated with the sensors. In the course of welding, as the joint moves relative to the electrode, a control signal is generated which aligns the welding electrode with the joint of the parts being welded. In case of industrial interferences, the resulting displacement of the seam axis relative to the joint is corrected by a seam control system. The device is capable of maintaining a constant width of the seam in the course of welding.
