For increase of mining technique capacity at production and restoration wear resistant facings are widely applied. In this work, impacts of impulse welding of an intermediate layer on structural factors and facture toughness of wear resistant surfacing are studied. It, is established, that applying an intermediate layer with periodic impulse «teeth» forms a heterogeneous texture of intermediate layer, causing higher fracture toughness of wear resistant surfacing. It, is shown that defects made by current impulse have promoted a fine-grained structure of HAZ facing and grain-boundary allocation of grainy pearlite.
