Boilermakers specialize in assembling, installing, and maintaining large containers or vessels such as boilers, closed vats that contain various liquids and gasses. As part of their job, boilermakers read blueprints to ascertain the right positions, layout and assemble prefabricated parts of the different containers or boilers and inspect them for leaks. After the process is completed, they clean the boilers. Repairing or replacing broken joints, pipes and valves are also a boilermaker's responsibilities.
Boilermakers work in diverse industries and factories. This is an entry level job. A high school diploma or equivalent is sufficient to become a boiler maker. However, most employers will only hire you if you have some hands-on experience in the field. You can get this experience by working as an apprentice under an experienced professional.
