Ultrasonic detecting device and detecting method for interface corrugation of explosive welding composite material

Abstract

The invention discloses a detecting method for an ultrasonic detecting device for interface corrugations of an explosive welding composite material. The method comprises the following steps of 1. determining a detected object, wherein the detected object is a composite material and comprises a coating plate and a base plate which are composited together; 2. setting working parameters of the detecting device; 3. setting detecting speed of ultrasonic detection on the interface corrugations of the explosive welding composite material; 4. judging whether set detecting speed meets requirements on detection resolution ratio and work efficiency; and 5. carrying out the ultrasonic detection on the interface corrugations of the explosive welding composite material after a technique design is finished. The detecting method provided by the invention uses a high-frequency phased array ultrasonic detection technology so as to obtain detection images with high resolution ratio, and only high-precision mechanical scanning in the one-dimensional direction is required, so that the reliability of a system is high; a phased array probe is used to flexibly adjust the depth of focusing and the focusing column diameter of a detected wave beam through implementing different focusing rules; and therefore, flexible detection techniques on products with different parameters can be formulated.

Description

technical field [0001] The invention relates to a detection technology for evaluating the quality of an explosive welding process, in particular to an ultrasonic detection device and a detection method for the interface ripple of an explosive welding composite material. Background technique [0002] At present, the existing technology uses a high-frequency focusing probe to perform two-dimensional C-scan ripple imaging to detect the quality of the explosive welding process. The main problems of this technology are: the scanning speed is slow, and the position accuracy of the scanning device is very high, so the equipment cost At the same time, due to the slow scanning speed, it can only be used for laboratory testing in many cases and cannot be used for quality inspection in the production process.
