Methods: X-ray diffraction, hole drilling and other destructive and non-destructive methods.
Your needs: product quality and process optimization
SONATS provides a high quality package of services for residual stresses and materials analyzes.
Residual stresses cause detrimental distortion during component manufacturing. They also influence material cracking resistance and component lifetime: fatigue, stress corrosion, tenacity. Besides metallurgical and dimensional aspects, knowledge and control of residual stresses is decisive for product quality assurance and process optimization.
SONATS methods are applicable to any type of component and material, regardless of the expected residual stresses distribution :
Cases studies: depth inspection of compressive residual stresses after shot peening, control of fatigue test specimen preparation, prediction of part distortion in machining, qualification of a new manufacturing process, distortions due to heat treatment, raw material receipt quality control, influence of the filler metal on a MIG-MAG welding process, residual stresses after friction stir welding, residual stresses after laser welding, residual stresses after needle penning and high-frequency mechanical impact (HFMI), effect of stress relieving treatment, residual stresses onto HVOF deposit, residual stress on silicon wafers. Effect of substrate quality on residual stress in deposit, etc.
