Abstract
The embodiment of the utility model discloses a time of flight diffraction (TOFD) scanning rack and a TOFD detection device. The TOFD scanning rack comprises a first scanning rod, and a second scanning rod which is rotationally connected with the first scanning rod through a connecting piece. By adoption of the technical means that the TOFD scanning rack consists of the first scanning rod and the second scanning rod which is rotationally connected with the first scanning rod through the connecting piece, so that the TOFD scanning rack can change the angle according to the needs, a special workpiece can be detected, the detection range of a TOFD is greatly widened, and the production output is improved.
Description
Technical field
The utility model relates to the ultrasonic detection technology field, relates in particular to a kind of TOFD scanning frame and TOFD pick-up unit.
Background technology
Ultrasonic wave diffraction time difference method (Time Of Flight Diffraction, TOFD) scanner is to detect the mechanical hook-up of walking at pipeline when labour steel pipe weld seam, the TFOD scanner comprises the TFOD scanning frame of rod and the probe that is mounted thereon, can be along being parallel to the bead direction walking scanning of detecting a flaw.
