Abstract
Crack resistance and porosity of low carbon alloys in hardfacing using self-shielding flux-cored wire was investigated.
It was established that alloying the deposited metal with over 0.7 wt.% aluminium leads to increase in its martensite
phase content and decrease in its crack resistance. It was shown that maximal hardness of the deposited metal at an
insignificant decrease in its crack resistance could be achieved at the 0.5—0.7 wt.% aluminium content.
