Abstract

The invention belongs to the technical field of ultrasonic detection, and discloses a subsurface defect detection method, device and equipment and a storage medium. The method comprises the following steps: acquiring the surface roughness and the surface material corresponding to a metal sample to be detected; searching corresponding optimal laser detection power from a database according to the surface roughness and the surface material; and performing laser ultrasonic detection on the to-be-detected metal sample based on the optimal laser detection power to obtain a subsurface defect detection result corresponding to the to-be-detected metal sample. Through the mode, the optimal laser detection power is selected according to the roughness and the material of the metal sample to carry out laser ultrasonic detection, so that the laser ultrasonic detection precision and efficiency are effectively improved, and the accuracy of metal subsurface defect detection is further improved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic testing, and in particular, to a subsurface defect detection method, device, equipment and storage medium. Background technique [0002] Since the metal additive manufacturing process is a process accompanied by complex physical, chemical and other multi-physical field coupling, the manufactured parts are prone to defects such as cracks, pores, and impurities. These defects can seriously affect the performance of the part, and even lead to the damage of the part. Therefore, the problem of defect generation is a major obstacle affecting the development of laser additive manufacturing. How to reduce or eliminate the defect rate of parts is an urgent problem to be solved. At present, the traditional defect detection methods are divided into two types: destructive testing and non-destructive testing. The destructive testing cannot meet the needs of industrial production because of the damage to th...
