Boilermaker

Boilermakers assemble, install, and repair boilers, vats, and other large vessels. Boilers hold liquids and pressurized gases that are used in many industries. Boilers supply steam to drive turbines in ships and electric power plants. They are also used to provide heat and power in buildings. Large vessels such as tanks and vats are used in the processing and storage of many products.

Boilermakers follow blueprints to install large boilers on-site or assemble small boilers in a manufacturing plant. Boilers and other vessels are made in sections from molten iron or steel. Boilermakers align sections using plumb bobs, levels, wedges, and turnbuckles. They make sure the section edges fit properly and bolt or weld them together. They attach other necessary components, such as water tubes, valves, and gauges. Once a boiler has been assembled, boilermakers test it for leaks and weak spots. In most areas, there are state and local laws setting standards that boilers must meet.

Boilermakers regularly inspect and maintain boilers and update components such as burners to increase efficiency. Boilermakers repair boilers that are worn or damaged. They may have to take a boiler apart to fix it. Sometimes they strengthen joints or use pieces of metal to patch weak spots. At other times they must replace a whole section of a boiler. Boilermakers also install special equipment on boilers and tanks to prevent smoke or fumes from polluting the air.
