DEVICES AND METHODS FOR PRODUCING STRUCTURES MADE OF METAL MATRIX COMPOSITE MATERIAL Russian patent published in 2021 - IPC B23K20/12 

FIELD: construction engineering.

SUBSTANCE: inventions can be used in producing a structure made of a metal matrix composite material. The assembly (102) of a unit (200) is carried out which comprises at least two blocks (210, 220) of material (211) in the primary phase, a gap (202) which is arranged therebetween and in which a material (231) is arranged in the secondary phase. The unit (106) is pressed against at least one of the two press clamping plates (510, 520) in such a way that the blocks are moved in a direction towards each other and/or are held in the specified position. A rotating pin (600) is passed (108) for welding with friction, stirring the side along the specified gap from the front edge of the assembly to the rear edge. The length (622) of the rod stirring in the form of a shaft passes through at least the full width of the knot. The passage of the friction and mixing welding pin ensures the distribution of the material in the secondary phase in the material in the primary phase and the welding of the specified at least two blocks with each other.

EFFECT: invention enables producing high-quality structure made of a metal matrix composite material.
