FIELD: metallurgy.
SUBSTANCE: present invention relates to a method of making galvanized and annealed steel sheets. Method of making galvanized and annealed sheet steel involves the following steps: application on sheet steel of first coating consisting of nickel, annealing of specified coated steel sheet at temperature in range from 600 to 1200 °C, application of zinc-based second coating on sheet steel and alloying thermal treatment for production of galvanized and annealed sheet steel. Invention also describes galvanized and annealed sheet steel obtained using said method, as well as a welded joint, at least one component of which is galvanized and annealed steel.
EFFECT: galvanized and annealed steel sheet has low tendency to liquid metal embrittlement.
