Boilermakers install and maintain boiler systems. Boilermakers assemble, install, maintain, and repair boilers, closed vats, and other large vessels or containers that hold liquids and gases. Some boilermakers work in water treatment or air treatment facilities and may be tasked with reducing pollution from factories or improving water treatment plants. Although the name originated from craftsmen who made boilers, boilermakers in fact assemble, maintain, and repair other large vessels and closed vats. The boilermaker trade evolved from industrial blacksmithing; in the early nineteenth century, a boilermaker was called a boilersmith. Boilermakers are specialized artisans who mark off and fabricate structural steel and other metal stock to make or repair metal products and structures including boilers and pressure vessels. Becoming a boilermaker is a riveting career choice and holds a lot of responsibility and duties. Boilermakers align sections using plumb bobs, levels, wedges, and turnbuckles. They use metalworking machinery and other tools to remove irregular edges so that metal pieces fit together properly. They then join them by bolting, welding, or riveting. Boilermakers usually go through a formal apprenticeship which includes about four years of paid on-the-job training combined with classroom instruction. Unions and many employers offer these apprenticeships. To become an apprentice, one must be at least 18 years old and have a high school diploma or GED. Attending a trade or technical school combined with employer-provided training can accelerate the learning curve. Note: Questions are scrollable. Please let us know if there is an issue.
