Question: 1 / 400

What can be used in place of a tap hammer to check for panel delamination?

A coin

Using a coin as a substitute for a tap hammer to check for panel delamination is effective due to its solid, flat surface. When tapped against a panel, the coin can create a sound that indicates the structural integrity of the panel. If delamination is present, the sound will differ; it may sound dull or hollow rather than the sharper sound that would indicate a solid structure.

The other tools mentioned do not provide the same utility. A wrench, while potentially heavy, may not deliver a precise tap and could damage the panel. A screwdriver is generally used for fastening rather than for testing panel integrity and may not effectively convey the information needed about the panel’s condition. A paintbrush lacks the rigidity and weight necessary to create a sound indicative of structural issues. Thus, the choice of a coin stands out as the most appropriate tool in this context for checking panel delamination.
