【 摘 要 】

The structure, phase composition, and morphology of the surface layers of structural 1020, 1050, 1060 steels of the steel modified by the cathode spot of the welding arc are studied with the help of electron and optical microscopy. It is shown that the treatment of the cathode spot of the arc leads to grain refinement in the surface layer and causes its hardening. As a result of this treatment, partial or complete amorphization of the surface layer is possible.
