Ripple and Uniformity Measurement of a Phased-Array Testing-Machine for round-Bar Testing
Industrial testing of round bar material is commonly carried out directly in the testing line applying automated testing-machines. Due the simple handling possibilities and the excellent resolution, phased-array systems, preferably of type ROWA are applied for these tasks. Up to now, many special materials with associated non-standard specifications are still tested offline in immersion tanks or even manually. In addition to the small reference defects applied, the testing of those materials requires am in depth understanding of the variation of the defect signal along the complete circumference of the test body, generally referred to as Ripple and Uniformity. From the process point of view, it is of great advantage to transfer the offline test of special machines to the inline testing machine. In order to do this, a detailed measurement of the testing homogeneity under industrial conditions is one of the key points. For this purpose, a method and a measurement system, which allows measuring Ripple and Uniformity, was developed and set into operation.
