Boilermakers install, repair, and make boilers, closed vats, and other large containers that contain liquids, like oil, and gases. Boilermaking is physically demanding and sometimes hazardous, so proper precautions must be taken. Many Boilermaker jobs also include travel to work sites and require on-site living for a period of time. A Boilermaker’s day could include reading blueprints, casting metal pieces, bending them into shape, and welding or bolting metal pieces together to form the boiler or other containers. Other duties may include testing completed boilers, implementing efficiencies, and performing routine maintenance as necessary.
