ABSTRACT:
A method for making a joint between a small diameter metal tube and a large diameter metal tube by coating the outside of the small diameter tube with an adhesive and inserting it through a hollow cylindrical sleeve made of metal having the same or greater thermal coefficient of expansion as a small diameter tube such that it extends beyond the ends of the hollow sleeve. An area of the hollow sleeve is deformed circumferentially to displace the adhesive in the deformed area and make metal-to-metal contact between the sleeve and the small diameter tube. A portion of the sleeve is coated with adhesive and one of the sleeve or large diameter tube is positioned around the other with said one having a thermal coefficient of expansion the same or greater than the other and then deforming an area of said one of the sleeve or large diameter tube circumferentially to displace the adhesive in the deformed area and make metal-to-metal contact between the large diameter tube and the sleeve.
