Technical description

Checking friction stir weld quality by impacting a welded plate and comparing its damping capacity to a defect-free plate. A small difference means no defects. It helps detect tiny flaws that cause minimal, hard-to-measure frequency changes.

Simplified description

A technique checks the quality of welded plates by tapping them and comparing how they vibrate to a flawless one. If there's little difference in their vibrations, the weld is likely defect-free. This method is great for spotting small flaws that are usually hard to detect.
