TWI has built upon a wealth of experience in order to mature the technique of nonlinear ultrasonics into a fully functional detection system that has been validated on plate structures at TWI’s NDE laboratory in Middlesbrough. This has involved the design and optimisation of new hardware into the system to meet operational and market requirements for dimensions, weight and manufacturing cost.
TWI has built on our past experience in related areas to mature the NLUT scanner into a fully-functional FrictionHarmonics prototype that has been validated on plate structures in a laboratory at TWI’s Friction Stir Welding facilities near Sheffield. This work has included adding and optimising new hardware into the system so that it can meet operational and market requirements for dimensions, weight and manufacturing cost.
The NLUT scanner has been operational for over 18 months, which has allowed for new hardware and software to be commissioned to ensure robustness ahead of environmental testing. Environmental testing was carried out the friction stir welding facility at TWI Yorkshire to determine how the scanner performed in an industrial environment. The detection system has successfully demonstrated good accuracy and repeatability (see Figure 2) and now achieved TRL7 (Technology readiness level). (see Figure 2).
Preparation for Commercial Launch
The next phase of the project will include further refinement of the KiScan software to integrate an operator friendly graphical user interface (GUI). The final stage of the project will be to obtain certification for the safe use of the system to ensure it is market ready. The system will be commercially launched as KiScan from February 2021 with invitations for demonstration issued to industry in due course.
