Abstract

The invention discloses a laser root welding robot inside a pipeline and belongs to the technical field of pipeline welding. The laser root welding robot inside the pipeline comprises a weld joint welding device. A first transmission device is connected with the weld joint welding device. A front end machine base is connected with the first transmission device. A first gear motor is arranged in the front end machine base. One end of a connecting device is movably connected with the front end machine base. A crawler type traveling device is movably connected with the other end of the connecting device. One end of a pushing device is movably connected with the crawler type traveling device. A driving device is movably connected with the other end of the pushing device. A second transmission device is connected with the driving device. One end of the second transmission device is movably connected with the front end machine base. According to the laser root welding robot inside the pipeline, the welding fusion depth is large, the welding speed is high, accurate welding track guidance is provided for a laser welding head, and the quality of laser root welding is guaranteed.

Description

technical field [0001] The invention relates to the technical field of pipeline welding, in particular to a laser follow-up welding robot inside a pipeline. Background technique [0002] At present, the pipeline root welding process in the construction of long-distance oil and gas long-distance pipelines is completed by using an internal welding machine with multiple sets of arc welding torches. The working principle of this equipment is to manually align and position the arc welding torches on the internal welding machine The pipeline is divided into two semi-circles, and then downward arc root welding is performed on the inner groove of the pipeline respectively, and the whole welding trajectory process is uncontrollable. This type of equipment is limited by its welding process. The penetration of blunt edge welding is shallow, and a second heat welding cladding is required to penetrate the blunt edge of the pipe. This has not only affected the efficiency of the welding o...
