Abstract
The effect of non-metallic inclusions in the base metal on initiation and propagation of cracks in the deposited metal is considered. It is shown that, in addition to the non-metallic inclusions, the propagation of cracks in the deposited metal is also promoted by the hardening phases present in its structure, as well as by the polygonisation boundaries. However, the latter are not the initiating factors of cracking.
