Overview

What Does a Boilermaker Do?

Boilermakers build, install, and repair boilers, pressure vessels, and heavy industrial tanks — the massive steel systems inside power plants, refineries, and mills. Much of the work runs on outages and shutdowns: intense stretches of work, serious overtime, and travel between job sites. For those who can handle the schedule, few trades pay better per hour worked.

Why People Choose This Trade

  • Union apprenticeship (International Brotherhood of Boilermakers) — earn from day one
  • Outage and shutdown work pays heavy overtime and per-diem
  • Welding-intensive — certifications transfer everywhere
  • Small, tight trade: less competition, strong brotherhood culture
  • Power plant maintenance continues regardless of the energy mix

A Typical Day

  • Rigging and fitting heavy steel plate and tube sections
  • Code welding on pressure vessels — the core skill
  • Confined-space entry and work inside boilers and tanks
  • Torch cutting, grinding, and fitting repairs during outages
  • Strict safety protocols: this trade takes them seriously
