摘要

The paper considers the influence of nanosized particles of tungsten and titanium carbides on the structure and properties of the weld metal of welded joints made by automatic submerged-arc automatic arc welding.To add them into the weld pool,an alloying composition was used in the form of composite granules based on nickel powder(PNE-1 as per GOST 9722).The prospects of using nanosized tungsten carbide particles for modifying the weld metal with the aim to increase the values of impact strength were shown.However,titanium carbide in the same conditions leads to a decrease in the average value of impact strength,despite the modifying effect of its use.
