Welding joints in dissimilar metals

Abstract

Dissimilar metal and alloy weldability determination is based on the estimation of their bases interaction, at the same time the effect of the primary alloying element is also taken into consideration if possible. Qualitative joint production and prevention of intermetallic formation is determined to a large extent by the dissolution and following diffusion of the refractory metals in the liquid steel.
