|Title:||Spot Weld Analysis with Two-Dimensional Ultrasonic Arrays|
|Published:||January 01, 2004|
|Abstract:||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 is not only described, but results from carrying out the testing are documented as well. The three performance testing methods include the use of calibrated samples, comparisons with actual spot-welds, and a performance evaluation of the embedded fitting software, which was carried out by a comparison of results with reference fits supplied by the National Institute of Standards and Technology.|
