The invention provides a ray digital imaging detection system for pressure equipment girth welds. The system comprises a pressure equipment automatic scanning device which is arranged on the outside of pressure equipment for axially rotating around the pressure equipment, a ray emitting device which is fixed on the pressure equipment automatic scanning device for emitting rays to penetrate the girth welds, and a ray receiving and image processing device which is fixed on the pressure equipment automatic scanning device and is arranged opposite to the ray emitting device for receiving the emitted rays, converting optical signals of the rays into digital signals to generate girth weld detection images and processing the images to generate a processing result. The system can realize the digital imaging detection for the pressure equipment girth welds of different diameters by changing the diameter of the pressure equipment automatic scanning device, not only can greatly reduce the detection cost and shorten the development period of products, but also can quickly identify the defects.
