Reliable quality control: Nondestructive materials testing
The purpose of materials testing is to continuously improve the quality of products and production processes. It has established a firm place for itself in virtually all industrial sectors, including research & development, producing and working materials, for example, as well as all production processes.
It is impossible to totally avoid product flaws in connection with the manufacture of components or semifinished products. As a result, defects can occur when the product is used. Materials testing is an absolute necessity in avoiding these defects and enhancing quality and cost-effectiveness. A higher level of automation, productivity gains and a zero-defect strategy are the challenges in industrial manufacturing operations. Reliable quality control is necessary in order to be able to survive in the competitive arena.
Classifying the various testing methods
A material will be tested with respect to its physical, chemical or optical properties. A distinction is made between destructive and nondestructive materials testing. In non-destructive materials testing, the quality of a workpiece is tested without damaging the material, itself. In addition to nondestructive testing, materials testing is classified into further methods:
Destructive testing methods (e.g. tensile test and hardness test)
Physical testing methods (e.g. conductivity, damping properties, thermal expansion)
Chemical testing methods (e.g. element analysis, determination of corrosion behavior)
Metallographic testing (e.g. micrographs, fracture patterns)
