液体火箭发动机导管焊缝数字化X射线检测工艺研究

Research on Digital X-ray Inspection Process of Conduit Welds of Liquid Rocket Motor

为液体火箭发动机总装导管设计了透照工艺方案,从方案可行性、工艺可靠性等方面进行了论证,并针对适用导管的检测灵敏度、缺陷检出进行了产品检测试验,验证了导管焊缝无损检测系统的可靠性和检测效率能够满足导管智能生产线上的导管检测要求。

The transillumination process scheme is designed for the conduit on the final assembly line of the Liquid Rocket Motors,and the feasibility and process reliability are demonstrated,and the product detection test is carried out on the detection sensitivity and defect detection of the applicable conduit,which verifies that the reliability and detection efficiency of the pipeline weld nondestructive testing system can meet the conduit detection requirements on the conduit intelligent production line.
