Detection method and detection system for welding quality at terminal winding position

The invention belongs to the technical field of welding detection, and particularly relates to a method and system for detecting the welding quality of a terminal winding position, and the method comprises the steps: electrifying an enameled wire of a detected sample; coaxially placing the magnetic field detection element and the terminal of the detected sample, and moving the magnetic field detection element to the terminal of the detected sample so as to enable the magnetic field detection element to detect a corresponding measurement value; the welding quality of the terminal winding position of the tested sample is judged according to the measured value; according to the invention, the enamelled wire of the tested sample is electrified, when the enamelled wire is fully welded, the soldering tin enables the enamelled wire wound on the terminal to be short-circuited, and the current directly flows from one end of the terminal to the other end, and when the enamelled wire is not welded completely, a magnetic
