Shipbuilding. "Liberty" ships. Welding is more important than ever before in shipbuilding, saving time, weight and steel. This work is done at a nearby plant which formerly turned out freight cars. This worker is welding top plates to angle frames for a merchant ship under construction at a large Eastern yard. 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.
