Abstract

The invention discloses a friction welding system and method for a slender piece, which belongs to the field of welding technology, and includes a slender piece to be welded, a clamping piece A, a swinging piece, a piece to be welded and a clamping piece B; the clamping piece A is used to fix the slender piece to be welded and to provide reverse upsetting force for welding; the clamping piece A divides the slender piece to be welded into a left static section and a right swing section; It is divided into a left gradual bending section and a right friction section; the clamping piece B is used to fix the workpiece to be welded, and is used to provide welding positive upsetting force; the clamping piece B divides the workpiece to be welded into a right static section and a right static section. The left friction section; the driving pendulum is used to drive the right swing section to swing, so that the welding end surface of the right friction section and the welding end surface of the left friction section are friction welded. The friction welding system and method for slender parts of the present invention can solve the weldability problem of friction welding of longer parts or slender parts.

Description
