摘要: 无损检测技术经历了3个发展阶段,即无损探伤、无损检测和无损评价。目前一般统称为无损检测(NDT),而不是特指上述的第二阶段。无损检测技术在产品质量控制中起着不可替代的作用,很多无损检测技术是从航空航天装备的制造和检验中发展起来的,在承压设备制造和焊接等工业领域也有着广泛的应用。中国航天科技有限公司旗下的乐凯医疗科技有限公司,与其他几家跨国感光材料企业一道,在传统射线检测领域服务多年,生产的立方体和T颗粒卤化银系列工业无损探伤胶片,是航天"黑科技"之一。本文介绍了无损检测技术的发展、检测方法,以及在航天和铁路桥梁上的应用。

Abstract: Nondestructive testing technology has gone through three stages of development, nondestructive inspection, nondestructive testing and nondestructive evaluation. At present, NDT is generally referred to the nondestructive technology collectively, rather than referring specifically to the second stage mentioned above. Non-destructive testing technology plays an irreplaceable role in product quality control, and a wide range of applications developed in the manufacturing and inspection of aerospace equipment, as well as applied in the manufacturing and welding of pressure equipment. As one of the "black technology" in aerospace technology, a series of industrial non-destructive flaw detection X-ray films, with cube and T-particle silver halide, produced by Lucky Healthcare Corporation, a subsidiary of China Aerospace Technology Co. Ltd., has been serving for many years in traditional x-ray detection as same as the several other famous multinational photosensitive 46 materials enterprises. This paper introduces the development of NDT technology, testing methods, and its application in aerospace and railway bridges.

Key words: nondestructive testing, NDT, NDT X-ray film
