Magnetic Rectification of X Ray Radiographic Inspection Image Twisty for SSAW Pipe

YU Guangju

Abstract

It will produce magnetic field due to affection by direct current welding power supply during the welding of spiral submerged arc welded pipe.It will still remain residual magnetic.It designed a magnetic rectification unit aimed at image interruption by pipe residual magnetic when X ray TV inspection pipe ends.This unit is simple with frame with convenient operation and very good rectifying effect.
