Description

technical field [0001] The invention belongs to the technical field of quality detection of layered metal composite materials, and in particular relates to an ultrasonic detection device with the function of applying a coupling agent and a use method thereof. Background technique [0002] Layered metal composite material is a new type of metal composite material prepared by explosive compounding of any same or dissimilar metal. The overall performance of the layered metal composite plate mainly depends on the combination of the corrugated interface of the composite plate, such as material defects. Factors such as panel type, gap, and exhaust may affect the interface morphology of the layered metal composite board, causing local erosion strips, melting and other poor bonding of the layered metal composite board, which will easily lead to the subsequent failure of the layered metal composite board. Significant quality risks exist during machining. At present, conventional non...

Problems solved by technology

However, in the actual testing process, there are the following difficulties: 1. When testing a large number of layered metal composite panels, the process of applying the couplant is cumbersome, and the application of the couplant requires a lot of testing time for the testing personnel, which reduces the cost of ultrasonic testing. 2. Due to the narrow and long structure of the phased array probe, the detection surface of the phased array probe and the layered metal composite board to be detected The contact area of ​​the phased array probe is small, and the stability of the phased array probe is poor during the rapid detection process. It is difficult to grasp the coupling state between the phased array probe and the detection surface of the layered metal composite board to be detected, which will easily lead to the interruption of the phased array ultrasonic imaging detection process. , thereby seriously affecting the detection efficiency; 3. The existing clamping device for supporting the phased array probe has a complex structure and is not easy to operate. It requires two people to cooperate with the operation at the same time, which is inefficient and wastes human resources.
