Використання мокрого наплавлення для валів малого діаметру

Abstract

One of the most widespread technologies of restoration of diametrical sizes of shafts is their surfacing in the environment of protective gases. However, with such repairs of small diameter and longitudinal shafts, unacceptable deformations arise, and casting shortenings are associated with excessive heating in the process of surfacing. The paper proposes a technology of wet surfacing that minimizes heating during welding, and consequently all the negative consequences associated with it.
