The x-ray method does not measure stress directly but measures strain from which stress values are calculated. Residual stresses are measured using either of two techniques. The first is the single exposure technique (SET). This technique gives the user a very quick and efficient method to perform a stress measurement and is particularly suited to cases where many measurements are needed quickly. The second is the multiple exposure technique (MET).

In article “Residual Stress Characterization of Welds Using X-Ray Diffraction Techniques” you can find good explain for your inquiry and it is applying this method for several types of Welding process.

Hallo Amulya,

I am no specialist in this field, but I believe, you can get information by applying the stress-strain relation of the material. The relationship between stress and strain is a macroscopic property and must be known for steel. The strain can be determined microscopic by detecting the lattice constant using XRD. A deviation from the unstrained lattice parameter gives you direct the information of the strain.

Dear All, I kindly want to know technically if energy or power consumption has any significant or beneficial effect on residual stresses in any structural component...Thanks.
