| titleOfInvention | A detection method for defects in the inclined plane of cemented carbide six-sided top hammer |
| abstract | The invention discloses a method for detecting defects in the inclined plane of a cemented carbide six-sided top hammer, comprising the following steps: preparing a comparison test block of the same material according to the cemented carbide composition of the cemented carbide six-sided top hammer to be detected; Open detection holes and arcs on the slope of the comparison test block; place the probe of the phased array ultrasonic detector on the top or bottom of the comparison test block for testing to obtain the shear wave sound velocity of the top hammer material, and calibrate the detector. and detection sensitivity setting; set the test parameters of the phased array ultrasonic detector; then perform flaw detection on the bottom of the cemented carbide six-sided top to be tested to determine the specific location of the defect. In the method of the invention, the testing method, the selection of the probe, and the optimal configuration of the wedge for the probe are designed according to the characteristics of the six-sided top bevel and the edge of the cemented carbide, and the test, the detection sensitivity and the detection of the sound velocity of the top hammer material are completed by designing the test block. The calibration of the instrument realizes the defect detection of the inclined plane and edge of the cemented carbide six-sided top hammer. |
