Abstract
A magnetic flux leakage and electromagnetic acoustic transducer joint testing device for a drill pipe at wellhead, including a mounting table, a limiting frame, a detection mechanism, and a signal processing mechanism. The limiting frame is mounted on the mounting table, and provided with the detection mechanism. A middle of the detection mechanism is provided with the drill pipe. The detection mechanism is connected to the signal processing mechanism. When the drill pipe passes through the detection mechanism when being lifted or lowered within the wellhead, the detection mechanism, integrating a magnetic flux leakage detection probe and an electromagnetic ultrasonic detection probe, will perform overall detection of the drill pipe. A magnetic flux leakage and electromagnetic acoustic transducer joint testing method is further provided.
