Automatic welding quality detection device and method

The invention discloses an automatic welding quality detection device and method, and relates to the field of welding quality detection, and the key points of the technical scheme are that the automatic welding quality detection device comprises a controller, a data analysis module, a ray probe, an ultrasonic transmitter and an ultrasonic receiver; the ultrasonic transmitter and the ray probe are electrically connected with the controller; and the ultrasonic receiver, the ray probe and the controller are electrically connected with the data analysis module. According to the method, ultrasonic detection and radiographic detection are carried out on the welding position of the object to be detected at the same time, the three-dimensional model capable of clearly representing the grain distribution of the welding position is established in combination with the radiographic detection information and the ultrasonic detection information, and the welding quality is evaluated through the three-dimensional model; and
