Is your component under stress?

RUBIG Competence Center provides roentgenographic measurement of residual stresses or residual stress profiles in component surface areas. Thereby, RUBIG helps customers to gain crucial knowledge regarding strength, long-life fatigue strength and regarding influences from mechanical or spark erosion manufacturing.

Every component, tool or any welded structure is under residual stresses. Even raw materials, which are used to manufacture and heat-treat components, are not free of residual stresses.

Residual stress is tension within a closed system which is shielded from external forces or moments. The residual stresses equalize each other over the cross-section of a component, for which reason residual tensile and compressive stresses always appear together. The most reliable and most accurate method for measuring residual stress is the X-ray diffractometer analysis (RDA) according to DIN EN 15305.
