Polyurethane Adhesive Bond Inspection
Polyurethane adhesive bond inspection technique and appropriate probe selection
Bond testing is a fairly straight forward task when utilising the Go / No Go set up. However, it can be challenging when dealing with multiple layers of various materials.
In ideal conditions, the A-Scan displays the echoes based on the individual layer and the reflection from each layer of material is captured from the echoed signal (reflection) for thickness and integrity verification.
