Residual stress measurement laboratory
Our residual stresses and materials characterisation laboratory provides our measurement and analysis services not only in the laboratory but also in-situ at your production site.
Discover our services ou measurement and characterization methods:
DIMENSIONAL CONTROL AND METROLOGY
SONATS provides many ways to control your machined parts:
– Precision roughness meter
– Precision profilometer
– Three-dimensional measuring machine
– Laser scan
CONTOUR METHOD FOR RESIDUAL STRESS MEASUREMENTS
The contour method is a destructive technique to characterize the distribution of residual stresses in a part section. It is often used to optimize manufacturing and forming process. We provide measurements services on your site or in our laboratory.
EDDY CURRENT TESTING FOR RESIDUAL STRESS MEASUREMENTS
The testing of residual stresses via multi-frequencies eddy current is a non-destructive method used to optimize manufacturing and several mechanical processes and control and qualify parts on assembly line. SONATS provides services of residual stresses testing via eddy current in laboratory or on site.
MEASUREMENTS AND ANALYSIS OF RESIDUAL STRESSES
The SONATS laboratory uses destructive and non-destructive methods (X-ray diffraction, incremental hole drilling, mechanical relaxation method etc.) and provides comprehensive expertise of residual stress and analysis of metallic materials.
INCREMENTAL HOLE DRILLING
Incremental hole drilling strain gauge method (Incremental Hole drilling technique) is a semi-destructive method widely used in the energy, aeronautical and land transport sectors.
SONATS is equipped with all the means and tools necessary for metallurgical analysis and controls.
All of our investigative methods can be used to complete an expert analysis, especially for residual stress measurements and dimensional controls.
RING CORE METHOD
Our team of experts can conduct the Ring Core Method analysis, another strain gage method with high depth of investigation and high sensitivity to the strains.
X-ray diffraction (XRD) is a reliable decades-old technique for the analysis of residual stresses on a wide range of mechanical parts and materials in various industrial sectors.
