Abstract
A method of joining tubular structures using friction welding is disclosed. The invention provides a method of joining a first tubular structure having a conical contact surface to a second tubular member 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.
