Welding operation track, large pipeline girth welding device and welding method

Abstract

The invention provides a welding operation track, a large pipeline girth welding device and a welding method, and relates to the technical field of welding devices. The technical problems that the large pipeline girth welding device is manually taken and fixed, and time and labor are wasted are solved. The welding operation track comprises a frame body, an electromagnetic gripper and a welding adjusting device, and the frame body is of an annular structure and is fixed to a circular seam of a to-be-welded pipeline through the electromagnetic gripper; a welding gun for welding is movably mounted on the frame body through the welding adjusting device; and the frame body is of a reconfigurable flexible structure and comprises a plurality of sections of track units made of elastic steel plates, and part of or all the track units are connected end to end and spliced together to form the frame bodies with different diameters so as to be suitable for welding operation of pipelines with different diameters. The automatic welding device is used for automatically welding the welding seam of the large round pipeline, and has the advantages of simple structure, easiness in mounting, convenience in operation, full automation in the whole welding process after the mounting is completed, and high automation degree.

Description

technical field [0001] The invention relates to the technical field of welding devices, in particular to a welding operation track, a large-scale pipeline circular seam welding device and a welding method. Background technique [0002] Pipelines are widely used in industrial transportation, and the development level of pipeline welding automation is increasing day by day, but there are still few products that can automatically weld large pipelines. At present, with the increase of super large projects, the automatic welding of large pipelines is becoming more and more important. [0003] The applicant finds that the prior art has at least the following technical problems: [0004] At present, the welds of large pipelines are mainly welded manually, and the welding device is manually used for circular seam welding, which is not only poor in automation, but also time-consuming and laborious, with low welding efficiency and low welding quality.
