Failure Analysis

Surface corrosion or pitting? Intergranular or stress corrosion cracking? Weld defects or high temperature corrosion? Failure can occur in many different ways for various reasons, such as material defects, shortcomings in the design and the application of materials or unforeseen interactions of complex influences.

In the event of failure the consequences are often costly and, in the worst case, can have catastrophic effects on the business. Failure cases can lead to the temporary breakdown of machines and facilities or even to serious accidents.

The suitability of a material for a specific requirement or environment and the clarification of a failure case is therefore an important issue. The many years of experience of our experts make it possible to identify failure mechanisms and work out solutions to prevent further failure together with you.

If necessary, we not only examine the individual component but also the entire process. This leads to a consolidated, comprehensive analysis, which we present to you in the form of a detailed PowerPoint presentation or a Word report, and additionally explain the findings in a face-to-face conversation. We will also be pleased to advise you on the selection of materials in order to avoid failure events in the future.
