How to Become a Millwright

Every large machine in a factory or power plant relies on precision alignment and expert setup.
Millwrights are the skilled professionals who install and maintain that equipment.

Millwrights assemble, install, align, and repair heavy machinery in manufacturing plants, refineries, and industrial facilities.
They ensure that equipment operates safely and efficiently, often using advanced measuring tools and blueprints.

If you’re mechanically inclined and enjoy technical, hands-on work, becoming a millwright can lead to a stable and specialized career in industrial maintenance.
