The defects in metal materials can affect the performance of metal materials, and the detection of defects in metal materials is a hot research topic, which has important engineering practical significance. Introduced in this paper, the defects of metal material types, analyzes the principle of ultrasonic flaw detection, put forward a kind of ultrasonic signal denoising method based on the improved HHT algorithm, the experimental results show that the method has good effect in terms of defect detection.
