Millwrights install conveyor systems, escalators, giant turbines and generators.  Millwrights install and do maintenance on machinery in factories and do much of the precision work in nuclear power plants.  Millwrights are skilled construction mechanics who study and interpret blueprints, and then put their knowledge and expertise to work drilling, welding, bolting and doing whatever else is necessary to assure that the cogs of industry are in perfect working order.

Millwrights work with a variety of hand and portable power tools, and frequently cut, join and fasten metal construction materials usuing welding equipment and oxy-acetylene torches.
