Problems solved by technology

[0003] Aiming at the deficiencies of the existing solutions, the present invention provides a welded pipe device suitable for threaded pipes, which can weld the same weld seam by setting up a plurality of simple and easy-to-disassemble welding devices, and at the same time set a scale to accurately grasp each weld. The angle of the welding point of the device is used to re-melt the uneven solder to ensure the welding adhesion of the weld seam without causing false welding

Abstract

Provided is a pipe welding device suitable for a screwed pipe. The pipe welding device comprises a rack and a welding device, the rack is provided with multiple detachable adjusting brackets, a welding device which conducts welding on a welding seam from different angles is installed on each detachable adjusting bracket, and a scalar device which completes reading of welding angles of the welding devices through relative translation is arranged on the rack and the detachable adjusting brackets. According to the pipe welding device suitable for the screwed pipe, the same welding seam is welded through the welding devices which are simple and easy to disassemble; meanwhile, the scalar device is arranged to accurately master the angles of the welding points of all the welding devices so as to conduct secondary melting on uneven solder, the welding sealing property of the welding seam is guaranteed, and false welding is not produced.

Description

technical field [0001] The invention belongs to the field of steel pipe production equipment, in particular to a welded pipe device suitable for threaded pipes. Background technique [0002] Threaded pipes are mainly used in large-scale pipeline construction projects such as oil transportation. Because pipelines in these fields usually require larger diameters, it is difficult to produce pipelines that meet the requirements using straight seam pipeline technology. Threaded pipes are in production The pipe needs to be welded in a spiral manner. The existing technology uses the pipe to rotate and the welding torch to cooperate with the pipe to rotate. However, this method is not simply vertical or parallel because the direction of rotation of the pipe and the direction of welding of the weld seam , which makes it difficult for a single welding torch to cooperate with the wire feeding structure during welding, and the existing technology solves this problem by adjusting the wir...
