The cladding layer shape, dilution, microharclness, microstructure and distribution of alloying elements were investigated. The cladding layer is characterized by large dilution rate, fine microstructure, narrow heat-affected zone, narrow alloying elements segregation, high hardness, high contents of alloying elements and low contents of Fe.展开更多
