FIELD: the invention refers to the field of nondestructive control.
SUBSTANCE: on the surface of the detail they measure with the aid of the nondestructive mode a physical parameter according to whose meanings one can judge about the values of tensions in the corresponding zone of measurements. In quality of a physical parameter it is possible to choose the work of the output measured with the aid of the nondestructive method of contact difference of potentials, according to the minimal value of which one can discover the zone with maximal tensions on the surface of the detail.
EFFECT: possibility quickly and accurately discover dangerous zones on the surface of details.
