Abstract
During spin-welding of an end ring to a container body, the weld area is subjected to a radial pressure by means of a wire cable tourniquet under the action of a pneumatic cylinder. The interference fit between the ring and body is measured by reference to the torque required for their slow speed relative rotation or to the axial force required for their assembly and, according to the measured interference fit, the radial pressure applied by the tourniquet during welding is controlled.
