e-stress
Measurement of residual stresses in railway wheels with UT-EMAT technology
Including acquisition hardware, visualization software and sensors, this easy-to-handle device is designed for manufacturing and maintenance operations without the need for any coupling agent. During the EMAT inspection, a sensor is moved over different points of the rim and the volumetric stress state of the wheel is obtained at each point.
