Abstract
A compound arrangement comprising a first component of metal being brazed to a second component of metal. The first component has an external cylindrical surface touching an cylindrical internal surface of the second component. The second component clasps the first component tightly, so that the second component exerts compressive stress on said external surface of the first component.
