||Solderers and Brazers
- Align and clamp workpieces together, using rules, squares, or hand tools, or position items in fixtures, jigs, or vises.
- Melt and apply solder along adjoining edges of workpieces to solder joints, using soldering irons, gas torches, or electric-ultrasonic equipment.
- Melt and apply solder to fill holes, indentations, or seams of fabricated metal products, using soldering equipment.
- Smooth soldered areas with alternate strokes of paddles and torches, leaving soldered sections slightly higher than surrounding areas for later filing.
- Sweat together workpieces coated with solder.
- Dip workpieces into molten solder or place solder strips between seams and heat seams with irons to bond items together.
- Position stones and metal pieces, and set, mount, and secure items in place, using setting and hand tools.
- Make repairs, such as enlarging or reducing ring sizes, soldering pieces of jewelry together, and replacing broken clasps and mountings.
- Burn grooves or crevices in molds in order to correct defects, using soldering guns.
||Aircraft Structure, Surfaces, Rigging, and Systems Assemblers
- Position and align subassemblies in jigs or fixtures, using measuring instruments and following blueprint lines and index points.
- Align, fit, assemble, connect, or install system components, using jigs, fixtures, measuring instruments, hand tools, or power tools.
- Weld tubing and fittings or solder cable ends, using tack welders, induction brazing chambers, or other equipment.
||Welders, Cutters, and Welder Fitters
- Lay out, position, align, and secure parts and assemblies prior to assembly, using straightedges, combination squares, calipers, and rulers.
- Operate brazing and soldering equipment.
||Welding, Soldering, and Brazing Machine Setters, Operators, and Tenders
- Assemble, align, and clamp workpieces into holding fixtures to bond, heat-treat, or solder fabricated metal components.
- Dress electrodes, using tip dressers, files, emery cloths, or dressing wheels.
