Layout Workers, Metal and Plastic

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.
