METHOD OF THE CONNECTED BODY MANUFACTURING Russian patent published in 2018 - IPC B29C65/06 B60R19/03 

FIELD: instrument making.

SUBSTANCE: method of the composite power structure manufacturing includes: bringing the first element and the second element into contact with each other, at least one element of the first element and the second element is made of the thermoplastic polymer, and the second element has a recessed portion on a connection surface to be connected to the first element. Welding the first element and the second element together, including welding the first element and the second element contact portion by the thermoplastic polymer melting with the frictional heat. Latter is produced at the contact portion during the first element and the second element relative movement, under condition, in which the first element and the second element are in contact with each other.

EFFECT: technical result achieved when using method according to invention consists in fact, that to ensure the steady pressure application to the second element flange portions for strong welding with the first element flange portions.
