METHOD AND SYSTEM FOR ADDITIVE PRODUCTION AND RECOVERY USING SINTERED WIRE MANUFACTURING AND FEEDING IN SITU Russian patent published in 2021 - IPC B23K26/342 

FIELD: sintered wire manufacturing.

SUBSTANCE: group of inventions is intended for the manufacture of sintered wire and feeding in situ into a system for laser surfacing with filler wire in the additive production and/or recovery of a super-alloy component. A high-pressure container is connected to a system for feeding at least two powders to the powder-mixing zone. A heating device placed in the high-pressure container heats the mixture to ensure liquid-phase sintering of the powders and the formation of sintered wire, which is continuously fed to the system for laser deposition of a deposited material layer on the base material. The welding system contains a laser energy source and a welding head for receiving the specified sintered wire. The sintered wire is deposited immediately after its manufacture. The higher plastic properties of the wire material in the heated state allow it to be produced from a brittle material.

EFFECT: use of sintered wire reduces the presence of pollutants during laser surfacing, while the sintered wire provides a chemical composition similar to that of the base material of the super-alloy component.
