Problems solved by technology

However, the angle of the welding wire can only be adjusted by adjusting the angle of the casing relative to the beam during installation before starting welding, and cannot be adjusted at any time during the welding process, and it is even more difficult to achieve automatic adjustment

Abstract

The invention provides an internal and external welding device for welding a steel tube and a flange. An internal-welding welding gun [9] is regulated in vertical position, horizontal position and axial position as well as an angle relative to a radial line of a to-be-welded steel tube, and an external-welding welding gun [5] is regulated in radial distance from a pointed position to a welding point, and axial position, so that the welding guns and the welding point are kept on proper distance, and an included angle between a welding wire and the radial plane of the to-be-welded steel tube isproper. The angles, relative to the axis of a to-be-welded steel tube [2], of the welding guns further are regulated by swing fingers, so that the welding wire is kept at a proper angle relative to ato-be-welded seam. Compared with the prior art, the internal and external welding device has the advantages that regulation on spatial positions of the welding guns in the internal and external welding mechanism, the angle, relative to the welding seam, of the welding wire and the like can be realized, basis is provided for realizing a fully-automatic welding device for welding the steel tube andthe flange, and especially, welding quality is improved and welding operation is more user-friendly through regulation on the angle of the welding wire.

Description

technical field [0001] The invention relates to an internal and external welding device for welding a steel pipe and a flange. Background technique [0002] When welding large pipelines, the more effective welding process is double-sided welding, that is, relying on internal and external welding devices to weld both internal and external sides of the connection between the steel pipe and the flange at the same time. This requires a device that can perform both internal and external welding, that is, an internal and external welding device. [0003] Chinese invention patent ZL201210166735.2 "A Double-sided Welding Device for Steel Pipe and Flange" discloses an internal and external welding device for welding steel pipe and flange, wherein "the internal welding device includes an internal welding head, a set The first guide rail on the machine platform, the welding machine base slidably arranged on the first guide rail and the pushing device for pushing the welding machine ba...
