Full-Text - Abstract

Mobile hardness testing is on the advance: In these times of cost pressures and higher quality requirements there is a quick and economical supplement to stationary hardness testing in the modern production process. The application possibilities are far ranging, this includes large parts (fig. 1) as well as small parts, and especially applies to positions which are difficult to access (Fig. 2).

There are two different physical methods which are particularly recognized in the practical field: the statical UCI method and dynamic rebound hardness testing. The decision as to which method is used mainly depends on the test task.

The lecture explains the basic principles of both test methods and compares, using examples from the practical field (e.g. hardness testing in the Heat Affected Zone of welds), the application of both methods.

In addition to this, the subjects critically discussed are the factors of influence for hardness testing, such as surface preparation at the test location or the wall thickness of the part to be tested, e.g. pipelines. Just to round things off, tips are given from daily hardness testing.
