The DISSIMILAR project has two primary aims:

1. position and size defects accurately, compensating for the distortive effects of the anisotropic, inhomogeneous austenitic/ferritic weld.
2. improve the overall inspection quality through the use of phased array technology such that the inspections provide vastly better signal to noise quality (compared to present probes), are faster (by orders of magnitude) and provide accurate, quantifiable and digitally recordable data.

The project will deliver a revolutionary new technique for the inspection of dissimilar joints using an innovative model based approach to compensating for metallurgical barriers and two advanced phased array probe types (TRL and annular) using novel materials and concepts.
