Non-destructive examination is conducted on samples of any size / The samples adhere to EN UNI 15305 and ASTM 915 standards / A 6-axis robot mounts the X Ray Diffractometer
StressX, an X-Ray Diffractometer designed for Residual Stress Analysis, conducts non-destructive testing of samples. The diffractometer's head is affixed to a versatile 6-axis robot, enabling the analysis of samples of varying dimensions and shapes. StressX can be installed in an enclosed cabin for laboratory use or on a four-wheel trolley for on-site analysis.
Residual stress can result from processes such as machining, grinding, rolling, deep drawing, welding, thermal hardening, and shot peening. Quantifying residual stress helps prevent fatigue damage and ensures the durability and safety of materials. StressX offers a flexible solution for determining residual stress in samples of any size through the unique combination of a compact X-ray diffractometer and a 6-axis robot.
6-axis robots boast positioning accuracy and repeatability as precise as 20 μm and a positioning range of up to 895 mm radius from the robot center. The measuring target is determined using a video camera for X-Y pointing and a laser for Z positioning. The laser's accuracy can be less than 10 μm, with a measuring range of up to 300 mm from the goniometer center.
With 6 degrees of freedom, the measuring positions and angular ranges are only limited by the size of the robot.
Applications of the Stress-X include:
- Identifying residual stress on sprocket wheels
- Identifying residual stress on car motor parts such as cam axles, connecting rods, engine shafts, equalizers, etc.
- Identifying residual stress induced by deep drawing in household appliances, structural parts, etc.
- Detecting operational stress on gas conducts
- Identifying operational stress on large tensioned structures
- Measuring the efficiency of shot-peening and rolling of stressed components
- Defining the quantity of retained austenite on bearings and parts of diesel motor injectors
- Detecting residual stress in castings such as cast iron parts of tool machines and aluminum components
- Identifying stress induced by welding, including laser and electron welding
- Exploring the correlation between residual stress and stress resistance of aluminum alloy car rims
- Optimizing working parameters for swarf removal to enhance the stress resistance of mechanical components
- Detecting residual stress on helicoidal and leaf springs
- Identifying critical zones after applying workloads in arms and aeronautics
The X-Sense® proprietary software by GNR is designed to support various analysis tasks, starting from data acquisition with full control over all process and hardware settings (generator and tube, detector, measurements set up) to data analysis, which involves calculating residual stress or retained austenite values.
A user-friendly software for analyzing uni-axial, bi-axial, and tri-axial residual stress has been created in accordance with ASTM E915 practice and UNI EN 15305 standards.
