Working as a boilermaker can be a rewarding career that requires a high degree of knowledge, a dedication to excellence and technical skills. Boilermakers work in the construction, industrial, manufacturing and shipbuilding industries.
To succeed in this field, you need to meet specific requirements. In this article, we discuss what a boilermaker is, how to become a boilermaker, important skills for a boilermaker and the salary and job outlook.
What is a boilermaker?
Boilermakers are tradespeople who create, assemble, test and install tanks, furnaces, towers, heat exchangers and other heavy metallic structures. A boilermaker can be responsible for erecting water storage that holds over 700,000 gallons of water or for constructing specific components for a hydroelectric power station. Boilermakers can work in various industries to include:
Iron and steel industry
What does a boilermaker do?
Boilermakers are responsible for handling issues related to boilers, vats and other large structures. Boilers can heat water and fluids under absolute pressure, generating electric power that provides power and heat to buildings.
Ships, factories and buildings use vats and tanks to store large products and process chemicals. Boilermakers can also install heat-resistant materials in pressure vessels or fireboxes and maintain the large pipes used in dams to move water to and from hydroelectric power generation turbines. Other tasks boilermakers perform are:
Interpreting and reading blueprints to discover the locations, dimensions and positions for constructing the boilers
Directing crane operators
Loading and unloading materials
Laying out components and marking cuts
Making bends and welds on components before joining them
Welding, burning and gouging
Assembling boiler tanks
Testing and inspecting the boiler system for any defects or leaks
Using hand, power tools and welding tools to replace broken pipes, regulators, water columns and valves
Installing pre-made boilers into residential and commercial buildings
Cleaning the boilers and boiler furnaces
Erecting supporting steel beams and columns
Boilermakers may sometimes have to take a boiler apart to fix it or strengthen joints using metal pieces to mend weak spots. On other occasions, they may replace a whole section of a boiler.
How long does it take to become a boilermaker?
With a high school diploma or GED, most boilermaker apprenticeships take 4-5 years to complete, comprised of both classroom/virtual and hands-on apprentice work.
Apprenticeships must be applied to and the boilermaker apprentice must be registered with an employer that can offer hands-on accredited training. After the coursework, the apprentice must take a trade test administered by the Department of Labor.
Salary and Job outlook
A boilermaker's salary depends on expertise, education, level of experience and other factors. According to the Bureau of Labor and Statistics (BLS), the median annual income for boilermakers in 2019 was $63,100 per year, or 29.93 per hour. The lowest 10% earned less than $39,840, while the highest 10 percent earned more than $94,440.
The median income refers to the wage at which half of the workers earned more than that amount and half of the workers earned less. The apprentices earn less than qualified boilermakers, but they make more as they acquire more skills.
According to the BLS, the employment of boilermakers may increase by 1% from 2019 to 2029. An estimated 1,400 job openings across the country may be available every year during this period. The need to replace workers who have transferred or retired may contribute to this increase in job openings.
