METHOD OF OBTAINING AN INEXTRICABLE CONNECTION BY SOLDERING A PART FROM A COPPER WIRE MATERIAL WITH A COPPER PART Russian patent published in 2019 - IPC B23K1/00 B23K103/12 B21F27/10 

FIELD: manufacturing technology.

SUBSTANCE: invention can be used in production of filtering and heat exchange elements from wire material, in particular at connection by soldering part from copper wire material to part made of copper. Preliminary copper coating is applied on silver coating, it is coiled in spiral and pressing of workpiece from wire. Billet is placed in contact with copper part and joint heating of obtained billet and copper part is performed at temperature 800÷840 °C in protective medium with reception of junctions in points of contact between coils of wire and part from copper.

EFFECT: invention provides for permanent and permanent connection of rigid and strong porous part from wire with part made from copper; uniform distribution of wire material over the finished part volume is possible.
