Intelligent welding seam detection method and system based on ultrasonic waves

The invention discloses an intelligent welding seam detection method and system based on ultrasonic waves, and relates to the technical field of ultrasonic detection. A digital signal feedback coefficient Szxs, a first data set and a second data set are obtained after processing and conversion are carried out through an information verification module and a data conversion module, a welding seam feature extraction model is established through a data processing module for training and fitting, a welding seam feature adjustment index Tzzs is obtained, the welding seam feature adjustment index Tzzs is matched with a welding seam evaluation adjustment threshold value T, and the welding seam evaluation adjustment threshold value T is obtained. According to the welding seam detection adjustment evaluation strategy scheme, the welding seam state of a welding part is detected in real time, processed and calculated, then the welding process and the state of a welding material are evaluated, a large number of unqualifi
