There are many unique shapes that must be formed from massive pieces of steel to construct the several sections of a ship. Heavy metal fabricator apprentices learn the processes and procedures of the shipyard’s Steel Fabrication Shop. They learn to use a variety of tools and machines that cut, burn, bend, move and press steel into shapes needed for ship construction. Apprentices also learn how to lay their work out to validate the shape prior to extracting it. They create a large portion of the parts and plates needed to build aircraft carriers and submarines.
