Approach - Mapped to Production Requirements
The method(s) must be single-side inspections that can follow a flange, navigate large changes in geometry, have spatial resolution near 1-mm and have an overall inspection speed of at least 1 m/min.
The inspection method(s) must be deployed on multiple automotive bodies in white (BIW) containing adhesive joints produced by the OEMs. Complex geometries can impede the inspection strategies.
A two-step validation process has been followed: first successfully inspect the flat engineered adhesively bonded specimens, representative of automobile flanges. Secondly, deploy the inspection method on production car bodies.
