Embodiment Construction

[0033] Such as figure 1 As shown, this embodiment introduces a fully automatic external welding machine for steel gas pipelines, which is used for welding the splicing seam between the first pipeline 10 and the second pipeline 20 .

[0034] Such as figure 1 As shown, the fully automatic external welding machine includes a track 1, a welding trolley 2 and a welding torch 3, the track 1 is a round tube type, the track 1 is set on the outside of the first pipeline 10, and the track 1 and the first pipeline 10 should be kept as close as possible Coaxial, the welding trolley 2 is connected to the track 1, and the welding trolley 2 can walk at a constant speed on the outer peripheral surface of the track 1, the welding torch 3 is connected to the welding trolley 1, and as the welding trolley 2 walks, the welding torch 3 is connected to the first pipe The splicing seam between 10 and the second pipe 20 is welded.

[0035] Such as figure 1 As shown, a plurality of positioning bolts...

Abstract

The invention relates to the technical field of pipeline welding, in particular to a full-automatic welding machine for a steel gas pipeline. The full-automatic welding machine comprises a track, a welding trolley and a welding gun. A driving mechanism is arranged on the welding trolley. An adjusting mechanism is fixedly arranged on the welding trolley. A welding gun bracket is arranged between the welding gun and the welding trolley. The welding gun is fixedly connected with the welding gun bracket. The adjusting mechanism can adjust the distance between the welding gun bracket and the welding trolley. The welding trolley is fixedly provided with a range sensor and a controller. The range sensor is used for measuring the distance from the range sensor to the connecting seam between a first pipeline and a second pipeline. The range sensor is used for transmitting an electric signal to the controller. When the numerical value measured by the range sensor exceeds the threshold value of the controller, the controller controls the adjusting mechanism to move so as to drive the welding gun bracket to get close to or far away from the weld seam. The full-automatic welding machine has theadvantages that the position of the welding gun can be adjusted in real time, the welding quality can be improved, and the mounting precision of the track can be reduced.

Description

technical field [0001] The invention relates to the technical field of pipeline welding, in particular to a fully automatic external welding machine for steel gas pipelines. Background technique [0002] In the process of natural gas transportation, gas pipelines must be used for transportation. The installation and welding of gas pipelines are an indispensable part of laying pipelines. For gas pipelines, the quality of welding directly affects the service life of gas pipelines. The speed of welding directly affects the engineering time of pipeline laying. In the current welding process of steel gas pipelines, the more advanced technology is to use a fully automatic external welding machine to weld the joints of the two pipelines. [0003] The existing fully automatic external welding machine includes a welding trolley, a track and a welding torch. The track is set on a pipe and is detachably and fixedly connected with the pipeline. The welding trolley is set on the track a...
