Abstract
The utility model provides an auxiliary tool for pipeline flange welding, which relates to the technical field of pipeline flange welding and comprises two fixing components and a pressing and supporting component. The fixing assembly comprises a transverse positioning section and a vertical positioning section which is vertically and upwards arranged on the transverse positioning section; during auxiliary positioning, the abutting supporting assembly is located between the two fixing assemblies and abuts against the faces, away from the vertical positioning sections, of the transverse positioning sections of the two fixing assemblies at the same time, so that the faces, close to the vertical positioning sections, of the transverse positioning sections of the two fixing assemblies abut against the inner pipe walls of a pipeline and a flange. And one surface, far away from the pipeline, of the flange abuts against the vertical positioning section. According to the technical scheme, the pipeline, the inner pipe of the flange and the outer side of the flange are positioned and fixed, the thickness of the flange does not need to be considered, and therefore the flange has the advantages of being high in applicability and capable of being matched with various flange thicknesses.
