Title:
INERTIA OR FRICTION WELDING OF CONICAL COMPONENTS INTO ELLIPTICALLY-SHAPED HOLES IN A PIPE OR TUBE
Document Type and Number:
WIPO Patent Application WO2004091840
Kind Code:
A3
Abstract:
A method of joining tubular structures using friction welding is disclosed. The invention provides a method of joining a first tubular structure (11) having a conical contact surface (62) to a second tubular member (50) with an elliptical contact orifice by placing the conical surface within the contact orifice, rotating one of the structures, and pressing them together to form a weld. The invention further discloses airbag inflators constructed using the method of the invention.
