Abstract
Circumferentially spaced jacks for clamping and supporting a pair of tank sections in end-to-end relationship during welding include spring biased gripping members mounted on at least some of the tank engaging ends of the jacks which initially grip the surfaces of the tank sections and then move in a direction to force the ends of the tank sections together as the jacks are extended.
