An oil pipeline butt welding equipment and welding process

Abstract

The invention relates to the technical field of oil pipeline welding, in particular to an oil pipeline butt welding equipment and a welding process, comprising a base, a displacement mechanism, an adjustment mechanism and a welding mechanism. An adjustment mechanism is arranged on the side, and a welding mechanism is arranged in the middle of the upper end face of the base; the present invention can solve the existing problem in the process of butt welding of elbows by manual means in the prior art: the elbows placed horizontally are easy to be placed in the welding process. Rotational displacement occurs, which reduces the effect of butt welding on the elbow; the angle between the other elbow and the horizontally placed elbow is difficult to install and use. It is easy to cause the elbow after butt welding to be used and installed. The environment does not match; the partially welded elbow needs to be turned over to be able to weld the unwelded part of the elbow, which reduces the efficiency of butt welding of the elbow.

Description

technical field [0001] The invention relates to the field of oil pipeline welding processing, in particular to an oil pipeline butt welding equipment and welding process. Background technique [0002] In the process of oil exploitation, oil pipelines are needed for transportation. The types of oil pipelines are mainly classified into straight pipes and bent pipes. Welding between straight pipes is very common, but it is not common to weld butt joints of bent pipes, so the existing technology is usually the first Place one elbow horizontally, then manually connect the other elbow to the horizontal elbow, and then manually weld the joint of the two elbows. However, there are usually the following problems in this process: 1. Because The horizontally placed elbow is usually difficult to be stably clamped, so the horizontally placed elbow is prone to rotational displacement during the welding process, which reduces the accuracy of the butt welding of the elbow. [0003] 2. It i...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the present invention provides a butt welding equipment for petroleum pipelines, which effectively solves the problem that the horizontally placed elbow is prone to rotational displacement during the welding process and the manual welding method is difficult to make another elbow The tube is accurately butted with the horizontally placed elbow, which may easily lead to gaps at the joint of the two elbows. The manual welding method makes it difficult to accurately control the angle between the other elbow and the horizontally placed elbow according to the requirements of use, which may easily lead to completion. The elbow after butt welding does not match the installation environment during use. In the process of manual welding of the elbow, it is necessary to turn over the partially welded elbow to weld the unwelded part of the elbow, etc.
