Abstract

Overlapping connections of sheet metal members in structural components are ested for cracks or flaws which are primarily the result of wear and tear under operating load conditions. For this purpose a test hole is made into or through the overlapping sheet metal members whereby each sheet metal member is provided with its own test hole portion. As long as the connection is still in good condition, adjacent test hole portions remain in register with each other. A sensor is inserted into the test hole. The sensor provides an indication of a faulty connection when the test hole portions are no longer in register. Several different types of sensors may be employed. The monitoring of the test holes and/or sensors may be made in a manual or automatic manner.
