Use complicated shop mathematics to calculate irregular curves, angles, and pitch. Apply principles of radial-line development combined with parallel-line development to devise and calculate patterns. Manufacture items and systems with dovetailed seams, set-in-bottom seams, burred-bottom seams, or wire or lock seams. Set up, adjust, and operate powered and non-powered tools and forming equipment to form sheet metal into cylindrical, tapered, conical, and irregular shapes. Select, cut, bend, and install hardware on all types of assemblies as determined by pattern, layout, and specification. Fabricate templates for sheet metal components. Assemble and fabricates components of stainless steel, black iron, galvanized iron, terne plate, copper sheet, magnesium, honeycomb material, and alloys and installs by use of bolts, screws, and lock-seams. Apply riveting, soldering, and spot-welding techniques for appearance, durability, and structural soundness. Work with a...
