This paper describes a threefold method of testing the performance of an array-based ultrasonic tool for nondestructive testing of spot welds. The tool is described in its capabilities, use, and advantages over existing counterparts. Performance testing for and the results from carrying out the testing are described. The three performance testing methods include 1) the use of calibrated samples, 2) comparisons with actual spot-welds, and 3) a performance evaluation of the embedded fitting software. The test of the fitting software was carried out by a comparison of results with reference fits supplied by the National Institute of Standards and Technology.
本文介绍了一种用于点焊无损检测的基于阵列的超声工具性能测试的三重方法。文中描述了该工具的功能、用途以及相对于现有同类工具的优势。阐述了进行性能测试的过程及测试结果。这三种性能测试方法包括：1）使用校准样本；2）与实际点焊进行比较；3）对嵌入式拟合软件进行性能评估。拟合软件的测试是通过将结果与美国国家标准与技术研究院提供的参考拟合进行比较来进行的。
