1. Shipfitters: These are the puzzle makers who figure out which piece of the ship, called an individual assembly, goes where. Shipfitters also begin connecting the assemblies with plasma cutters, plate rollers, drills, and welding machines.
2. Riggers: Individual assemblies are constructed upside down by many of the trades, including…
3. Inside Machinists, who build pieces using such tools as lathes, drill presses, and CNC machines, and…
4. Boilermakers, who use techniques like metal grinding and tack welding. Riggers flip these assemblies right-side up and connect them to transporters and cranes to move them into position.
5. Outside Machinists: Experts in alignment, outside machinistsinstall the toys: propulsion machinery, steering gear, radars, antennas, and weapons systems. They make sure each piece is placed properly on welded bases known as foundations.
6 Hull Welders: After the shipfitters have made initial connections, hull welders use four kinds of welding (stick welding, MIG, flux-cored arc welding, and submerged arc welding) to melt a filler material in with the base material, fully fusing the ship’s joints. The process creates a bond as strong as, or stronger than, a plate that hasn’t been welded at all.
7. Painters: These workers prep the ship by blasting it with abrasives or power sanders, then cover it in paints that provide protection from salt and sun exposure. They do this while standing on scaffolding built by 8. Carpenters.
9. Pipe Welders and Fitters connect pipes for sewage, water, and machinery, using mirrors in tight spaces.
10. Marine electricians lay out, install, and test every electrical system.
11. Cable pullers route 322 miles of cable throughout the entire ship.
12. Sheet-Metal Mechanics create air ducts for the ventilation system.
13 Joiner/Insulators install living quarters, furniture, and insulation.
