Abstract

The invention provides a large pipeline girth welding operation device and a welding method, and relates to the technical field of welding equipment. The technical problems that a welding operation device needs to be moved by laying a track, is time-consuming and labor-consuming, and cannot be moved at will are solved. The large pipeline girth welding operation device comprises a movable positioning base, a girth welding operation face non-coupling adjusting device installed on the movable positioning base and a welding gun installed on the girth welding operation face non-coupling adjusting device. Rollers and a positioning control module are arranged on the movable positioning base, and the positioning control module is in signal connection with the rollers so as to control the rollers to advance, retreat and steer. The welding method comprises the steps that the device moves into a pipeline in a linear mode; the device is positioned and fixed; a welding telescopic mechanical arm is adjusted to the welding seam position; welding is carried out; and the device moves forwards for next-time welding. The large pipeline girth welding operation device is used for girth welding of large pipelines and has the advantages of being convenient to move, high in working precision, high in automation degree and wide in application range.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a large-scale pipeline circular seam welding operation device and a welding method. Background technique [0002] With the rapid development of the manufacturing industry, many welding working environments are not suitable for manual operation. Therefore, the demand for welding robots is increasing. Most of the traditional welding robots are large in size, and their weight, volume and operational complexity are difficult to meet the needs of welding work. Therefore, the requirements for simple operation and high degree of automation are becoming more and more urgent. [0003] The applicant finds that the prior art has at least the following technical problems: [0004] Most of the pipeline welding robots at this stage need to be installed with fixed rails, which cannot meet the requirements of convenient movement. The existing rail-mounted mobile welding robots do not...
