DEVELOPMENT ON WELDED SEAM DEFECT X-RAY INSPECTING IN-PIPE ROBOT POWERED BY BATTERY

In this paper,we introduced its systematical structure and operation principle for a X-ray inspection in-pipe robot for pipeline’s welded seam,it features big applied pipe scope,long distance working ability,high location accuracy,better interchangeability etc. The experiments prove that it is a desirable operation device for flaw detection of pipeline’s welded seam,the robot is valuable to be spread in pipeline engineering.
