Alining Large Cylinders for Welding
Abstract
Special tooling alines and holds internally-stiffened large-diameter cylindrical parts for welding. Alinement brackets attached to strengthening fins on insides of cylindrical tank sections. Jackscrews on brackets raised or lowered to eliminate mismatches between adjacent sections. Tooling substantially reduces costs while allowing more precise control and improved quality.
