(Zetec: Snoqualmie, WA) -- Zetec Inc. has published its latest on-demand webinar detailing a more effective approach to one of the most common and critical nondestructive testing (NDT) applications in aerospace MRO (maintenance, repair, and operations): inspections of bolt holes in multilayer materials.

The 40-minute webinar will discuss and demonstrate how using high-resolution C-scans and dedicated analysis displays for rotating-probe and eddy current array data can increase both eddy current inspection productivity and probability of detection.

“Rotating eddy current probes and traditional impedance and sweep displays lack the resolution to identify the individual layer where a defect resides. This can make it challenging to determine whether repairs are necessary,” says Nicholas Cardillo, eddy current sales engineering director for Zetec. “This webinar will show how to use readily available eddy current technology to better recognize signals of interest, understand flaw morphology, and identify layers where bolt-hole flaws are located without the use of encoders or secondary manual measurement methods.”
