  • Method and apparatus for radial inertia welding of dissimilar metals
    Patent number: 4387844
    Abstract: The invention discloses an apparatus for the radial inertia welding of a al band to the outer surface of a cylindrical metallic structure. The metals may be similar or dissimilar. The band is placed on the inside of a spinning collet and as the cylindrical structure is advanced thru the band, at a predetermined position, it activates the collet jaws, causing the band to be radially compressed onto the cylindrical structure. Friction between the rotating band and the cylindrical structure held by a tailstock creates heat and under the resulting collet jaw pressure welding action results.
