ABSTRACT:
Method and device for the rotational friction welding of plastic parts.A method for the rotational friction welding of plastics wherein a rotationally symmetrical plastic body is set in rotation and, as it rotates, is pressed against a welding location of a plastic part that is held stationary until plastification of the pressing surfaces of the plastic part and/or the plastic body is achieved, and wherein the rotationally symmetrical plastic body is braked to a standstill after plastifying and is held pressed against the stationary plastic part until the plastified pressing surfaces solidify, is known.According to the invention, the rotationally symmetrical plastic body is pressed at a circumferential speed of more than 7 m/s and a pressing pressure of less than 0.5 N/mm2against the welding location of the plastic part that is held stationary.Use for plastic tanks.
