  • Frictional method and machine for seaming tubular sections
    Patent number: 4106167
    Abstract: Metal cans are welded by frictional treatment of the materials joined. The treatment is provided by a rapidly rotating smooth hard friction tool e.g. wheel contacting a surface of the metal above the join while the parts joined are held in pressure contact by independent pressure exerting means and/or by the wheel itself. In the formation of can side-seams the wheel and the can are relatively traversed and a longitudinal continuous side-seam is formed which in the case of metal to metal joints is metallurgically homogeneous and may be characterized in that no signs of melting of the base metal are visible at the welded interfaces.
    Type: Grant
    Filed: October 30, 1975
    Date of Patent: August 15, 1978
