SYSTEMS AND METHODS USED IN WELDING PIPE SEGMENTS IN PIPELINE Russian patent published in 2022 - IPC B23K31/02 B23K37/53 B23K101/10 

FIELD: welding.

SUBSTANCE: present invention relates to a system for welding two pipes; it can be used for the production of pipes of stainless steel or pipes of other types of metals for the transportation of liquids, such as water, oil and natural gas. A system frame is made with the possibility of being placed inside pipes. There is a set of rollers made with the possibility of retention of the frame with the possibility of rotation. The system contains a welding torch, a drive engine that drives the set of rollers for the movement of the frame inside pipes, and a brake system retaining the frame from the movement in the set position inside pipes. A measuring sensor retained by the frame is made with the possibility of detection of characteristics of an area of a contact surface between pipes. One or more batteries retained by the frame are made with the possibility of powering the drive engine, the measuring sensor and the welding torch. One or more processors are functionally connected to the drive engine, the measuring sensor and the welding torch.

EFFECT: system structure provides reliable positioning and performing a welded joint, the accuracy of positioning of a welding torch, in which information about a contact surface profile, read by a sensor, is used as input parameters during outer pipe alignment.
