FIELD: machine engineering.
SUBSTANCE: invention is intended for permanent connection of closed circuit components made of dissimilar metals which cannot be joined together by welding due to fatigue failure of the weld during operation. The connection comprises male and female metal parts in which at least two holes are formed, wherein a through hole is made in the female part and a recess one is made in the male part. Metal cylindrical pins with a through inner hole, made of the same material as the male part, and well welded together and fused along the inside diameter of the pin with the material of the male part are installed in the holes by the press fit.
EFFECT: increased reliability of the connection of closed circuit components made of dissimilar materials.
