对无损检测行业进行了综述，介绍了主要技术，指出了当前的发展方向和挑战。目视检测可能是最广泛使用的无损检测技术，但它通常不涉及购买专用无损检测仪器，因此没有出现在市场估计中。无损检测市场由“五大”技术主导：射线照相、超声波、涡流。磁粉和渗透检测。在其他领域也有相当大的研究和发展努力。特别是对于利基市场。无损检测是一个成熟的行业，全球设备市场规模约为10亿美元。但是，用户的费用大大超过了这个数额，因为许多检查是高度劳动密集型的，而且经常需要为检查做大量的准备工作。尤其是在职。因此，继续努力提高检查速度，减少所需的准备工作和。如果可能，在不停机操作的情况下进行检查。除了一些值得注意的例外，发现大多数类型的缺陷是可能的。然而，进行检查通常不具有成本效益，因此降低总体检查成本是一个主要的研究和开发目标。其他重要的研究和发展领域是提高检查的可靠性，并在目前没有可用的检查技术的情况下找到解决办法。
The non-destructive testing (NDT) industry is reviewed, the major techniques being described and current development directions and challenges identified. Visual inspection is probably the most widely used NDT technique but it does not generally involve the purchase of dedicated NDT instrumentation so it does not appear in market estimates. The NDT market is dominated by the 'big five' techniques: radiography, ultrasonics, eddy current. magnetic particle and penetrant testing. There is considerable research and development effort in other areas.. particularly for niche markets. Non-destructive testing is a mature industry, the global market size for equipment being around $1 billion. However, the cost to users greatly exceeds this since much inspection is highly labour intensive, and extensive preparation for inspection is often required. particularly in-service. There is therefore a continuing drive to increase the speed of inspection, to reduce the preparation required and. if possible, to inspect without the need to shut down operation. With some notable exceptions, it is possible to find most types of defect. However, it is frequently not cost effective to do the inspection, so driving down overall inspection costs is a major research and development aim. The other significant research and development areas are in improving inspection reliability and in finding solutions in cases where there is currently no available inspection technique.
