Steel pipe welding auxiliary device

Abstract

The invention discloses a steel pipe welding auxiliary device which comprises a supporting seat. The supporting seat is installed at the upper end of a base; a welding position is arranged on the base; a liftable supporting plate and a pipe rotating mechanism are sequentially arranged on the side, away from the welding position, of the supporting seat; an arc-shaped guide rail is arranged on one side of the base; an adjusting mechanism used for placing a steel pipe is arranged on the guide rail; and a pressing plate for fixing the steel pipe is arranged on the adjusting mechanism. According to the steel pipe welding auxiliary device provided by the invention, two welded steel pipes can be fixed, rotated and in butt joint, so that the butt joint firmness and stability of the two steel pipes in the welding process are guaranteed, angle and height adjustment is convenient and labor-saving, manpower is saved, the operation efficiency is improved, time is saved, the welding quality is improved, and the problems of low welding quality and low welding speed caused by inconvenient fixation and easy movement in welding in the current steel pipe welding process are solved.

Description

technical field [0001] The invention relates to the technical field of steel pipe welding, in particular to a steel pipe welding auxiliary device. Background technique [0002] Welded steel pipe refers to a steel pipe with seams on the surface that is welded after bending and deforming a steel strip or steel plate into a circular, square, etc. shape. The blank used for the welded steel pipe is steel plate or strip steel. With the rapid development of continuous rolling production of high-quality strip steel and the advancement of welding and inspection technology, the quality of welds has been continuously improved, and the varieties and specifications of welded steel pipes have increased day by day, and seamless steel pipes have been replaced in more and more fields. Welded steel pipes have lower cost and higher production efficiency than seamless steel pipes. [0003] During the steel pipe welding process, it is difficult to connect two steel pipes. The angle and distance...
