Advanced technology hired for challenging inspection work

摘要

The inspection of austenitic stainless steel welds presents a higher level of difficulty in comparison with other welds because of the large grain structure, which for ultrasonic testing can cause beam skewing, splitting and attenuation. So, when James Fisher NDT (JF NDT) was awarded a contract to develop and implement an inspection procedure for austenitic stainless steel welds, the company contacted Neil Harrap, NDT Market Manager for Ashtead Technology, to discuss potential instrumentation configuration. As a result, an OmniScan~® MX2 was hired for a period of six months with a set of specialist probes.
