Problems solved by technology

[0002] In-pipe welding belongs to the existing technology, such as short pipes, direct manual welding and oblique welding can be used, but for long pipelines used in oil drilling and chemical industry, direct manual welding and oblique welding cannot be used. The reason is that , the long pipelines used in petroleum drilling and chemical industry require to minimize the number of welded joints to avoid safety risks, and require long-length complete pipes. Corrosion Resistant Alloy Coating

Abstract

The invention discloses a stretching-in type welding device which comprises a main body and a driving body. The main body and the driving body are both cylindrical; the rear end face of the main body is in butt joint with the front end face of the driving body; the main body can rotate relative to the driving body, and a rectangular groove is formed in the side surface of the main body; a first servo motor is fixedly installed in the groove; a rotating disc is fixedly installed on a rotating shaft of the first servo motor; the edge of the rotating disc is fixedly connected with one end of a driving rod; a rotating shaft of the first servo motor drives the rotating disc to rotate forwards or backwards; the other end of the driving rod is fixedly connected with a welding gun; an illuminating lamp is further fixedly installed in the groove; and the illuminating lamp is provided with a switch and a button battery. The stretching-in type welding device has the beneficial effects that pipeline internal welding work can be completed through an electronic control means, automatic adapting to changes of the inner diameter of a pipeline is achieved, and stable welding quality is kept.

Description

technical field [0001] The invention relates to the technical field of penetration welding, in particular to a penetration welding device. Background technique [0002] In-pipe welding belongs to the existing technology, such as short pipes, direct manual welding and oblique welding can be used, but for long pipelines used in oil drilling and chemical industry, direct manual welding and oblique welding cannot be used. The reason is that , the long pipelines used in petroleum drilling and chemical industry require to minimize the number of welded joints to avoid safety risks, and require long-length complete pipes. Corrosion-resistant alloy cladding. Due to the long length of the complete pipe, it is necessary to weld the inside of the pipe by means of penetration welding. However, how to realize the welding of the welding mechanism in the pipe, and how to solve the problem of how to realize automatic welding when the inner diameter of the pipe changes are technical problems...
