Abstract An original procedure is proposed for measuring residual stresses by combining the methods of holographic interferometry and probe holes. The difference of the orders of interference fringes for pairs of points on the surface of a body located on the directions of principal stresses is used as primary information. The results of the test experiment on measuring stresses in a plate deformed in the case of a simple shear and the results of measurement of residual welding stresses in two samples welded by a laser are presented.
