Abstract

A method of welding a layer of variable composition by electric arc, involving the introduction of two alloying materials into the weld pool with a change in their ratio during welding. The amount of alloying elements introduced into the weld pool varies in comparison with the required amount of these elements from 0.01 to 20% when the degree of alloying is reduced, and from 0.01 to .00% when it is increased, and maintains this amount during the time determined by the dependence: Vvany θΕ " % VSV · SŠVA Γ CE “ Cpož where Vvany “ volume of the weld pool, Vgy - welding speed, sSVA ” cross-section of the weld, C- amount of alloying materials introduced into the weld pool, varying according to the requirement, C - initial amount of alloying 0 materials introduced into the pool, from which the concentration is changed, C » - required amount of alloying materials in the weld; according to which the amount of alloyed materials is changed to the desired value.
