High School

A high school diploma is required for all applicants to the boilermaking trade. In the past, people have become boilermakers through on-the-job training, but apprenticeships are now strongly recommended. To gain an apprenticeship, an applicant must score well on an aptitude test. You can prepare yourself for this test and the career by taking math classes and shop classes throughout high school. Courses that give you the opportunity to learn blueprint reading, welding, and metalworking are especially helpful.

Postsecondary Training

Formal apprenticeships usually last four or five years. An apprentice receives practical training while working as a helper under the supervision of an experienced boilermaker. In addition to working, trainees attend classes in the technical aspects of the trade. Apprentices study subjects such as blueprint reading, layout, welding techniques, mechanical drawing, the physics and chemistry of various metals, and applied mathematics. While on the job, apprentices practice the knowledge they have acquired in the classroom. They develop such skills as using rigging and hoisting equipment, welding, riveting, and installing auxiliary devices and tubes onto vessels. Those with welding experience or certification will receive priority admission to apprenticeship programs.

Certification or Licensing

No certification or licensing is available for boilermakers and mechanics. Certification for welders is available from the American Welding Society and other organizations.

To obtain experience, try to work as a helper to a boilermaker or boilermaker mechanic.

Mechanical aptitude and manual dexterity are important characteristics for prospective boilermakers. Because the work can be very strenuous, stamina and physical strength are needed for jobs that require a great deal of bending, stooping, squatting, or reaching. Before they begin work, boilermakers may need to pass a physical examination showing that they are in good enough health to do the work safely. On the job, they must be able to work well despite noisy surroundings; odors; working at heights or in small, enclosed spaces; and other discomforts and dangers. It is also important that they be cautious and careful in their work and that they closely follow safety rules.
