Technical Field

The utility model relates to a pipeline pipe rack welding technology field, concretely relates to pipeline pipe rack welding is with shape frock of preapring for an unfavorable turn of events.

Background

Welding, also known as fusion welding, is a manufacturing process and technique for joining metals or other thermoplastic materials, such as plastics, in a heated, high temperature or high pressure manner. The welding of the pipes is to weld one ends of the two pipes together. When the pipeline is welded, the weldment is unevenly heated and a welding seam area is melted, and the thermal expansion of the material of a high-temperature area adjacent to a welding pool is limited by the surrounding cold-state material, so that uneven compression plastic deformation is generated. During cooling, the portion of the material that has undergone compressive plastic deformation is also restrained from free shrinkage by the surrounding metal and is stretched to some extent. When the molten pool is solidified, the weld metal is restrained to shrink and produce shrinkage tensile stress and deformation. The pipeline is plug-in butt welding, and the shrinkage stress pointing to the inside of the pipeline exists when the pipeline is welded, so that the trend of deformation towards the inside of the pipeline exists.

At present, pipeline for pipe stage welding frock when in actual use, the welded junction of pipeline does not have the structure of preapring for an unfavorable turn of events shape, and the welding of pipeline is in the welding and can slightly be sunken to the inside of pipeline after accomplishing to cause the pipeline whole bending deformation to appear, influence pipeline quality and life.
