Shipbuilding. "Liberty" ships. Welding is more important than ever before in shipbuilding, saving time, weight and steel. This welder is working on the foundation for steel pillars to support the decks on top of the shaft tunnel of a new merchant ship under construction at a large Eastern plant. All parts are prefabricated in this huge Eastern plant which formerly turned out freight cars. The completed sections are then carried six miles to the ways on flatcars.
