 APPLICATION IN NDT OF COMPUTER DIGITAL X-RAY REAL TIME IMAGE SYSTEM
 Abstract：Nondestructive testing (NDT) is one of the most commonly used scientific means to detect the internal defects without damaging the tested objects, therefore it is found widely applications in the industries of mechanical, petrochemical, aerospace etc. Radiographic Testing (RT) by X-ray is commonly used NDT method at present, its disadvantages are unavoidable for its long test period, high cost and environment pollution. With the development of computer technology, an emerging NDT method with digital X-ray real time image (DXRTI) is found increased application in industry. This paper presents the fundamentals and applications of computer numerical image technique (CNIT) in NDT with DXRTI technique, and introduced the new developed DXRTI software ‘XCX2000’ and its applications and economic benefit in weld defects detecting for LPG Cylinders.

 X-射线数字实时成像系统在无损检测中的应用

 摘要：无损检验(NDT)是一种常用以探测物体内部缺陷, 而无需损坏测试对象的科技手段。因此它被广泛地应用于机械工业、石油化工、航空航天等领域。照相检验(RT) 是当前最常用的一种无损检测方法，它的缺点是检测时间长、费用高以及污染环境。随着计算机技术的发展，X-射线数字实时成像技术（DXRTI）在工业领域得到了广泛应用。本文阐述了计算机数字图像技术在X-射线数字实时成像技术中的基础和应用。并且介绍了DXRTI软件‘XCX2000’的新发展及其在LPG圆筒的焊接瑕疵检测经济价值。
