Boilermakers Union Local No. 27

Boilermakers are essential to our every day life. They are particularly important at power plants where they assemble and repair boilers used to generate electricity. They also build pressure vessels, tanks and vats. Boilermakers also set up rigging and signal crane operators for lifting parts. Knowledge of geometry is useful for locating and marking reference points for columns or plates on the foundation. Work outside of St. Louis and beyond the state of Missouri may be required. Through the Boilermaker apprenticeship, participants receive four years of training in welding, blueprint reading, burning, rigging, layout, fit-up and related topics. On-the-job trianing and correspondence courses are also required.
