Boilermakers fabricate, install, maintain, and repair boilers, tanks, vats, pressure vessels, and other structures. These structures generate power, provide heat, and function as storage containers for oil, industrial chemicals or other liquids. Boilermakers primarily use welding and cutting equipment, but can also utilize tools to fuse, separate, and shape metal plates, sections, and components. Boilermakers contribute to the building, repair or maintenance of structures, including blast furnaces, bridges, rocket boosters, elevators, dams, and locomotives.
