Core Skills

  • Sheet metal pattern development and fabrication
  • Pre-engineered building construction knowledge

Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Sheet Metal Workers

Military sheet metal pattern development and fabrication directly support civilian sheet metal production and assembly.

How to prepare: Prepare a work sample showing a developed sheet metal pattern and the finished component for review by a prospective fabrication employer.

What the civilian work involves
  • Fasten seams or joints together with welds, bolts, cement, rivets, solder, caulks, metal drive clips, or bonds to assemble components into products or to repair sheet metal items.
  • Install assemblies, such as flashing, pipes, tubes, heating and air conditioning ducts, furnace casings, rain gutters, or downspouts in supportive frameworks.
Civilian tools and software (examples)
  • Autodesk AutoCAD
  • Applied Production ProFold

Structural Iron and Steel Workers

Military knowledge of pre-engineered building construction provides a foundation for structural steel assembly work.

How to prepare: Arrange supervised practice in structural steel connection and alignment through an ironworker training program.

What the civilian work involves
  • Connect columns, beams, and girders with bolts, following blueprints and instructions from supervisors.
  • Verify vertical and horizontal alignment of structural steel members, using plumb bobs, laser equipment, transits, or levels.
