Description

Technical field [0001] The invention relates to an X-ray digital imaging detection device for pipe row welds, which belongs to the field of detection devices. Background technique [0002] The serpentine tube bank and Morse wall tube panel are the main pressure components of the boiler, and the quality of the welds is very high, and the quality inspection is very important in the production process. The welds that need to be inspected on the tube row are mostly small-diameter pipe butt butt girth welds. The distribution of these welds is relatively random. Currently, only X-ray film photography can be used for weld quality inspection. [0003] Since the volume of the tube row can reach the geometric size of 20 meters in length and 4.5 meters in width, and the weight can reach several tons, it is often necessary to transport the tube panel to the inspection room for inspection by a special transport vehicle. During the inspection process, only one weld can be exposed and photograph...
