In this article (consisting of two parts), research has been carried out to study the features of the formation of the welded joints on heat-resistant steels using the example of the 10CrMo9-10 steel during the TIG and A-TIG welding with activating fluxes. Studies were also conducted into the effects of the surface conditions of the welded plates and the physical and chemical properties of activating fluxes on the features of the formation of the weld beads on the 10CrMo9-10 steel. This research has led to the development of recommendations for the compositions and properties of the activating fluxes for heat-resistant steels and a new high-performance flux which is intended for the A-TIG welding of these steels and increases the penetration capacity of the welding arc by 208% compared to the traditional TIG welding.
