FIELD: chemistry.
SUBSTANCE: device uses the principle of continuous extrusion with addition of filler metal wire into the groove separating the parts to be joined. The device comprises a rotatable drive spindle (13) with a head (14) at its end. On the upper surface (15) of the head (14) of the drive spindle an arc-shaped groove is made, forming an extrusion chamber (16), which is radially limited from the outside by the stationary annular metal shoe (17) surrounding the head (14) of the drive spindle, and by the support member (18) to enable filler metal wire deflection from its circular movement in the extrusion chamber (16) through the channel (19) for feeding.
EFFECT: device simplification.
