Abstract

The peculiarities of distribution of the size and composition of non-metallic inclusions in weld metal after adding into weld pool nanooxides of aluminum are described. It is defined that the inclusion of non-metallic oxide up to 0,3 μm can serve as centers of incipience of needle ferrite shapes and determine the conditions of formation of the microstructure of welds.
