Shipbuilding. "Liberty" ships. Welding is one of the most important advances in shipbuilding during the present century with the torch resulting in immense savings in time, material and weight in the building of ships. This welder is joining side plates to angle frames forming section of the propeller shaft tunnels on a new member of Uncle Sam's Liberty ships, under construction at a large Eastern shipyard which formerly turned out freight cars. The completed sections are then carried six miles to the ways on flat cars. Bethlehem-Fairfield Shipyards Inc., Baltimore, Maryland
