Abstract
It is shown that when developing the technology of electroslag cladding without penetration in the current-carrying mould, as well as in designing new moulds, it is necessary to take into account the role of contact resistances. Slag melt temperature can be a criterion for determination of the required surface melting of the clad (welded) surface. However, the dependence should be established between it and temperature on the contact clad surface.
 
 
Keywords: electroslag cladding, contact resistance, slag pool temperature, penetration
