美国NDT Supply.com, Inc.中国区服务商，可以提供优质的NDT服务
“无损检测（NDT）领域是一个非常广泛的跨学科领域，在确保结构部件和系统以可靠和经济高效的方式执行其功能方面发挥着关键作用。无损检测技术人员和工程师定义并实施测试，以定位和表征可能导致飞机坠毁、反应堆故障、火车脱轨、管道爆裂以及各种不太明显但同样麻烦的事件的材料条件和缺陷。这些测试的执行方式不会影响物体或材料的未来用途。换句话说，无损检测允许在不损坏零件和材料的情况下对其进行检查和测量。由于无损检测允许在不干扰产品最终使用的情况下进行检查，因此它在质量控制和成本效益之间提供了一个极好的平衡。一般来说，无损检测适用于工业检验。无损检测中使用的技术与医疗行业中使用的类似；然而，通常非生命物体是检查的对象。”无损检测资源中心
