5The work

Hands-on

Practical work with tools, systems, or physical environments

Conduct pressure tests on vessels, such as boilers.

6The catch

Know this first

What could make this a poor fit

The usual entry route includes an apprenticeship. Interest in the subject is not a substitute for supervised, paid training.

ChooseField take

The national benchmarks are mixed, so the work itself and the route in matter more than any standout pay or demand signal. It makes the most sense if hands-on work appeals to you and you are comfortable with an apprenticeship. Main tradeoff: The usual entry route includes an apprenticeship. Interest in the subject is not a substitute for supervised, paid training.

Actual responsibilities

What you would be trusted to own

Selected O*NET task statements, not a list of traits that applies to almost every career.

Conduct pressure tests on vessels, such as boilers.
Study blueprints to determine locations, relationships, or dimensions of parts.
Examine boilers, pressure vessels, tanks, or vats to locate defects, such as leaks, weak spots, or defective sections, so that they can be repaired.
Shape or fabricate parts, such as stacks, uptakes, or chutes, to adapt pressure vessels, heat exchangers, or piping to premises, using heavy-metalworking machines such as brakes, rolls, or drill presses.

Decision-changing realities

What could make this a poor fit

The usual entry route includes an apprenticeship. Interest in the subject is not a substitute for supervised, paid training.
BLS projects employment to shrink 1.8% from 2025 to 2035. Openings can still occur when existing workers leave.
Some core tasks take place on ladders, scaffolds, roofs, or other elevated work areas.

Before choosing the major or training

Run a cheaper test first

Take a supervised shop, maker, or trade class and finish one project while following its measurement, cleanup, and safety rules.
Ask an early-career worker which beginner task consumes the most time, what makes new hires quit, and what school or training failed to simulate.

The fuller career guide

How the evidence fits together

Pay and demand: reading the benchmark

The pay and outlook figures describe Boilermakers nationally. They do not establish the salary or number of vacancies available in your area.

Median pay is the middle wage across workers, not a starting offer. Projected openings include replacements as well as growth; neither measure predicts an individual worker's job security.

Before choosing a program

O*NET lists Critical Thinking, Active Learning, Active Listening among this occupation's skills. Ask a program to show the assignments, supervised practice, and assessment that develop these skills. Compare those examples with local job descriptions.

Common questions

Questions people ask about this career

Can I enter this occupation without related work experience?

BLS does not assign a related-experience requirement to the occupation. Employers may still ask for placements, supervised practice, a portfolio, or experience with particular tools. Check entry-level vacancies separately from experienced roles.

What should I check before paying for training?

Get the full prerequisite and completion timeline, total cost, placement arrangements, and any licensing eligibility in writing. Ask local employers whether they hire graduates from the route you are considering and whether paid training is available.
