Method for the production of a small-fraction titanium-containing filling for a cored wire

A method for the production of a small-fraction titanium-containing filling for a cored wire, comprising a use of at least one titanium-containing component and at least one iron-containing component,

• wherein an iron-containing diluting component or an iron-containing diluting component together with a titanium-containing enriching component is added to a basic titanium-containing component, said components are mixed to achieve a homogeneous blend,
• said mixing of said components is carried out, based on a general chemical composition of each component, in a proportion that enables a resulting general chemical composition of the blend to comprise:
• Ti content within a range of 68% to 72% inclusive, and
• Fe content and at least one of the following impurities:
• Al not to exceed 5%, V not to exceed 3%, C not to exceed 0.3%, Si not to exceed 0.5%, P not to exceed 0.04%, S not to exceed 0.04%, N2 not to exceed 0.5%, O2 not to exceed 2%, Bi not to exceed 0.01%, Pb not to exceed 0.03%, Mn not to exceed 1%, Sn not to exceed 1.5%, or another impurity,
• said basic titanium-containing component is production waste or product scrap from titanium-based alloys or any combination thereof having a general chemical composition that comprises:
• Ti content ranging from 50% to 99% inclusive, and
• at least one of the following impurities:
• Al not to exceed 50%, V not to exceed 10%, C not to exceed 1%, Si not to exceed 1%, P not to exceed 1%, S not to exceed 1%, N2 not to exceed 1%, O2 not to exceed 3%, Bi not to exceed 1%, Pb not to exceed 1%, Mn not to exceed 1%, Sn not to exceed 2%, or another impurity,
• said iron-containing diluting component is production waste or product scrap or products from iron-based alloys or any combination thereof having a general chemical composition that comprises:
• predominant content of Fe, and
• at least one of the following impurities:
• Al not to exceed 1%, V not to exceed 1%, C not to exceed 0.2%, Si not to exceed 1%, P not to exceed 1%, S not to exceed 1%, N2 not to exceed 1%, O2 not to exceed 1%, Bi not to exceed 1%, Pb not to exceed 1%, Mn not to exceed 1%, Sn not to exceed 1%, or another impurity,
• said titanium-containing enriching component is titanium sponge or titanium 3D printing powder or titanium 3D printing powder waste or technically pure production waste or product scrap from titanium-based alloy products with high content of titanium or any combination thereof,
• said titanium sponge has a general chemical composition that comprises:
• Ti content of at least 97%, and
• at least one of the following impurities:
• V not to exceed 1%, C not to exceed 0.1%, Si not to exceed 1%, P not to exceed 1%, S not to exceed 1%, N2 not to exceed 1%, 02 not to exceed 2%, Bi not to exceed 1%, Pb not to exceed 1%, Mn not to exceed 1%, or another impurity,
• said titanium 3D printing powder, or said titanium 3D printing powder waste have a general chemical composition that comprises:
• Ti content of at least 97%, and
• at least one of the following impurities:
• C not to exceed 0.3%, P not to exceed 1%, S not to exceed 1%, N2 not to exceed 1%, 02 not to exceed 2%, Bi not to exceed 1%, Pb not to exceed 1%, Mn not to exceed 1%, or another impurity,
