NEW WAY TO LOOK AT WELDED JOINTS

The design of one of the largest ore boats ever built for Great Lakes traffic, constructed by Erie Marine, Erie, Pa., uses repeated modules as building blocks for very low-cost construction of the boats. The mid-body of the 1000 ft ship is made up of 17 modules of essentially the same configuration. Instead of welding the long seams with the work laying on the floor, the large steel plates are stood on edge and welded in one pass with Airco's AVA (Automatic Vertical Aircomatic) process at about 25 ft/hr. Approximately 50 AVA welds are made in each module. The welding operation and the advantages of the process are described.
