Digital Radiographic Imaging Inspection System on The Tube to Tube sheet Welding Joints of Heat Exchanger
The tube to tube sheet welding joints of heat exchanger is the most critical joints. A special Nondestructive testing technology was proposed, which is based on the digital radiographic imaging automatic inspection system to the characteristics on the tube to tube sheet welding joints of heat exchanger. A new style Linear Diode Arrays as a device is used to receive ray, which will be fixed on a automatic rotating device, and be led to its rotation of the week through the rotating device to achieve the tube to tube sheet welding joints automatic inspection, finally the whole welding joints image was performed image processing in order to generate testing results. The results showed that this inspection system can be used to quickly and conveniently perform automatic inspection on the tube to tube sheet welding joints inspection,at the same time realize digital radiographic imaging of welds.
