A DETECTION DEVICE FOR WELDING FLAW REGION INSIDE OF PIPE HAVING SENSING QUANTITY OF FERRITE

摘要

The present invention relating to an apparatus for detecting defects in welded parts in pipes equipped with a ferrite percentage measurement apparatus is to closely detect defects on welded parts inside pipes by using a bogie having a structure for easily moving inside pipes. The apparatus for detecting defects in welded parts in pipes includes: a center frame (1) having a certain length; a first movable frame (2); a second movable frame (3); a third movable frame (4); a guide frame (5); a camera consisting of a first camera (72) and a second camera (76); a lighting device consisting of a first lighting device (82) provided in the lower part of a magnetic field generator (62), and a second lighting device (86) provided in one side of the center frame (1) adjacent to the second camera (76).
