Abstract

The effects of flaws in the insulating coating of an electric anisotropic steel, which are formed during its laser processing in accordance with the optimal technology used in industry, on the elastic tensile stresses induced in the metal by the coating and magnetic properties were investigated. It was shown that discontinuity of insulating coating at the location of laser-beam action does not lead to a decrease in elastic tensile stresses and deterioration of magnetic properties of steel.
