Abstract
The usage of special complex alloying and deoxidizing systems, combining various alloying components, micro-alloying components, deoxidizing and modifying elements that cannot be added into metal cored wires is the main aspect in the development of chemical compositions of welding consumables for high-strength steel welding. The optimal amount of acicular ferrite in the microstructure of the weld metal, as well as its high mechanical properties can be achieved by controlled introduction of titanium or titanium with boron. To ensure the best strength and ductility characteristics during complex micro-alloying of flux-cored wires, the titanium content should be about 0.04%, and boron – 0.003%
