To fabricate, assemble, install, erect, alter, maintain, repair, disassemble and demolish boilers, tanks, heat exchangers, fired heaters, reactors and other pressure vessels, boilermakers:

  • develop a layout and plan the sequence of work to be done
  • lay out plate, sheet steel or other heavy metal, and locate and mark bending and cutting lines
  • shape the metal using metal working machines such as shears and drill presses
  • cut metal plate and brackets using an oxy-fuel torch
  • chip and grind parts to shape for fitting together
  • fit and tack weld parts together using electric arc welding equipment.

Boilermakers also erect and install boilers, and repair and maintain existing boilers and related metal products.

Working Conditions
Updated Mar 08, 2016

Boilermakers work on construction sites, heavy industrial plants and fabrication shops. Working conditions often are cramped, dirty and involve exposure to chemical vapours, wetness or high noise levels. Installing boilers sometimes involves working on scaffolds. Boilermakers who work in confined spaces and high heights require the use of personal protective equipment and safety systems. The normal work week is 40 hours but some overtime may be required. Travel and staying in camps also may be required for boilermakers working in industrial plants.

Boilermakers may have to lift and move items that weigh over 25 kilograms. There always is some risk of injury when working with heavy equipment, especially when working at considerable heights. 

  • Strength Required Lift over 20 kg
Skills & Abilities
