  • Elliptical seam welding apparatus
    Patent number: 4040557
    Abstract: An apparatus for welding the circumference of an elliptical member is characterized by welding torch movably mounted on a support framework. A turntable rotates the elliptical member at a variable speed so that the travel under the welding torch is constant and that each point of the circumference of the elliptical member is successively the greatest distance above a horizontal reference datum. A control arrangement is provided to move the welding torch along the support framework so as to locate the torch adjacent each successive point on the elliptical member that is the greatest distance above the horizontal datum.
