Abstract

This paper presents the simulation and experimental results of the concept and validity of a dry-coupled roller probe inspection technique for in-process WAAM NDE. A parametric FEA simulation defined and optimised key probe inspection parameters such as coupling-medium thickness, surface contacting acoustic window and coupling medium depth. Experimental studies positively highlighted and demonstrated the feasibility of using surface profile and high-temperature compliant (< 250°C) silicone rubbers, with low attenuation (-0.8 dB/mm @ 5 MHz) for acoustic coupling through the as-built WAAM surface for representative defect detection and imaging of 3 mm side-drilled holes.
