摘要

The invention relates to the field of nondestructive testing, and is designed for the operating non-destructive ultrasonic testing of pipeline girth welds and fillet welds welding pipes with different diameters to the central conduit.; Proposed installation ultrasonic testing of girth welds and angular welds, comprising a mechanism for conveying ultrasonic transducers with pivoting lateral arms and movable arms, which are installed ultrasonic transducers, the guide belt device couplant supply unit electronic multichannel digital flaw detector, the control part and the block power. conveying mechanism has the ability to change the configuration for mounting on the guide belt different sizes, which enhances the versatility of the system.; Non-destructive ultrasonic testing is carried out during the movement along a predetermined conveying mechanism mounted on the nozzle surface of the guide belt, thus increasing the likelihood of defects is achieved through the propagation of ultrasonic waves in the material in different planes.
