International Brotherhood of Boilermakers, Iron Ship Builders, Blacksmiths, Forgers and Helpers

The Boilermakers are a diverse union of workers in construction, maintenance, manufacturing, professional emergency medical services, repair and related industries. Boilermakers build and repair ships, fishing boats, ferries, barges, cranes, boilers, tanks, pressure vessels, plate and structural fabrications among other things. These skilled workers often use acetylene torches, power grinders and other equipment for welding, burning, cutting, rigging, layout and bolting. It’s hard work, and heavy lifting and dedication to the craft is required.

The Boilermakers union consists of 63 local lodges, 1 district lodge, and 1 national lodge.
