Method for assembling two parts, parts and assembling made by this method

摘要

The method of assembling metal tubes (10,20) in a cryogen circuit involves machining one tube to form a ferrule (16) of hard metal. A second piece is formed into a receiving sleeve (24) of softer metal. It involves plastically deforming (F4) the sleeve a thread (F2). The sleeve is pressed against a frusto-conical section (14a) of the ferrule.
