FIELD: metallurgy.
SUBSTANCE: invention can be implemented for metal parts welding. Building-up material on base of nickel is pad-welded on surface of the first and the second steel parts at thickness sufficient for insulation of the thermal influence zone from successive welding. At least zones of thermal influence of each first and second steel parts are thermally treated. Thermally treated the first built-up surface is welded with the second thermally treated built-up surface using build-up material on base of nickel of the same composition.
EFFECT: preliminary preparation of welded surfaces eliminates post-welding thermal treatment and decreases or eliminates zone of thermal influence.
