METHOD OF CONNECTING METAL PARTS Russian patent published in 2016 - IPC B23K1/19 B23K35/30 B21D53/04 

FIELD: machine building.

SUBSTANCE: invention can be used for connection of metal parts with solidus temperature above 1,100 °C. On the surface (15) of first metal part (11) melting inhibiting composition (14) is applied containing suppressing melting component including at least 25 wt% of boron and silicon for reducing melting point of first metal part (11). Second metal part (12) is brought into contact with melting composition (14) in contact point (16). Metal parts (11, 12) are heated to temperature above 1100°C. Provide melting of surface layer of first metal part to form together with said component of metal layer in contact with second metal part. Obtaining compound (25) in contact point (16).

EFFECT: invention ensures production of strong connection between metal parts in simple and reliable way.
