Layout Workers, Metal and Plastic
Tasks
Core Tasks Include:
- Fit and align fabricated parts to be welded or assembled.
- Plan and develop layouts from blueprints and templates, applying knowledge of trigonometry, design, effects of heat, and properties of metals.
- Lay out and fabricate metal structural parts such as plates, bulkheads, and frames.
- Mark curves, lines, holes, dimensions, and welding symbols onto workpieces, using scribes, soapstones, punches, and hand drills.
- Compute layout dimensions, and determine and mark reference points on metal stock or workpieces for further processing, such as welding and assembly.
- Locate center lines and verify template positions, using measuring instruments such as gauge blocks, height gauges, and dial indicators.
- Lift and position workpieces in relation to surface plates, manually or with hoists, and using parallel blocks and angle plates.
- Plan locations and sequences of cutting, drilling, bending, rolling, punching, and welding operations, using compasses, protractors, dividers, and rules.
- Design and prepare templates of wood, paper, or metal.
Supplemental Tasks Include:
- Inspect machined parts to verify conformance to specifications.
- Brace parts in position within hulls or ships for riveting or welding.
- Add dimensional details to blueprints or drawings made by other workers.
- Install doors, hatches, brackets, and clips.
- Apply pigment to layout surfaces, using paint brushes.
