Beschreibung
Zusammenfassung:	The invention discloses a welding seam defect detection method based on multiple modes, in the welding seam defect detection method, a control module determines a quality evaluation index related to a target welding seam according to a guided wave characteristic parameter and an image characteristic parameter, and obtains a detection result whether a welding seam defect is detected or not based on the quality evaluation index. According to the welding seam defect detection method based on multiple modes, a second guided wave signal and a real-time image of a target welding seam serve as sampling data to finally determine the detection result of the welding seam defect, the second guided wave signal and the real-time image of the target welding seam are different types of sampling data obtained by different sensors, the second guided wave signal is obtained by a guided wave signal detection module related to the guided wave signal, and the surface real-time image and the X-ray real-time image are obtained by a
