Work Environment

The work of a boilermaker is not only physically demanding, it is dangerous since it involves working with open flames, extreme heat, in cramped, wet and noisy spaces and using heavy equipment and machinery. Boilermakers spend all their working hours on the plant floor. They work regular hours but could find themselves working overtime when they are up against strict deadlines or conducting emergency repair. Due to the unique nature of their product, boilermakers sometimes have to travel to install the boilers, vats or pressure vessels.

Career Prospects

Boilermakers are employed in the construction, engineering, mining, refinery and fabrication industries as well as in power plants. Therefore, there are numerous job opportunities that they can pursue. After seven years on the job, a boilermaker can rise to the position of supervisor or foreman and further still to project manager. There are career growth opportunities for those who are willing to stick it out and acquire the necessary years of experience on the job.

If you love doing manual work and would like to be engaged in a profession where you can choose your employment from a number of industries, then becoming a boilermaker is the right career choice for you.
