Boilermaker (Construction Boilermaker)

Construction Boilermakers use blueprints and other plans to construct, install, and repair boilers, tanks, and other large containers that hold liquids and gases. These vessels or boilers are used to contain everything from steam in an electric power plant to oil, chemicals and other liquids that we use daily. A Construction Boilermaker is designated as a Boilermaker under the Inter-provincial Red Seal program. Construction Boilermakers work on heat exchangers and other heavy metal structures and use brakes, rolls, shears, flame cutters and other tools during the course of their work. Because boilers and other heavy metal products typically last 20 to 40 years or more, Construction Boilermakers also inspect and maintain these structures to ensure they are safe and efficient. Construction Boilermakers also fit and join tubes, gauges, valves and other components that attach to the boiler or vessel and then test these systems for leaks or other defects. They sometimes are required to install heat-resistant materials around the systems to protect other workers. Construction Boilermakers can often be found in the maintenance departments of large industrial complexes and electric power generating plants.
