Abstract
A method for joining a tube and a plate includes forming a short connection stub which is integral to the plate. The stub is imperforate and has a cylindrical stub surface around the stub circumference and for engaging the tube. The distal stub edge is spaced from the plate and defines a circle. A cylindrical tube has an interior tube surface, an exterior tube surface and a tube end. The tube end is placed in telescoped relationship to the stub and the stub thereby contacts only one of the tube surfaces, i.e., the interior surface or the exterior surface. The tube and stub overlap at a junction. A substantially uniform force is then applied radially around the stub surface and the stub, the edge and the tube are urged simultaneously radially inwardly or outwardly with respect to the axis.
