With material defect detection, there are various possibilities with a flaw detector to check materials with respect to purity, fault-freeness or load-bearing capacity. A modern flaw detector is used to quickly and reliably check the possible defects and the inhomogeneity of a test piece. The quality of a workpiece is the basic prerequisite for the safety, productivity and success of a company. There are five different ways to inspect a workpiece for its purity, fault-freeness or load-bearing capacity without damage.
In the leak test, a distinction is made between vacuum method and overpressure method. If a component is examined for errors only by viewing, one speaks of a visual check. Ultrasonic testing allows a wide range of sources of error to be detected reliably and quickly. Examples of test workpieces are welds, forgings, bars, pipes, tanks and small and large containers. In some areas, testing and maintenance work is difficult or impossible to access due to structural conditions. A flaw detector can detect deficiencies without using electromagnetic waves (EMUS). For materials which are also electrical conductors, the eddy current test can be used as the test method. The conductivity test is most suitable for non-destructive material testing of metals.
A flaw detector is an important aid in quality control during the manufacturing process and during the inspection of components during operation, for non-destructive testing and analysis of materials. The aim is to avoid accidents involving personal injury, property damage and environmental damage.
