||Precious Metal Workers
- Solder parts together or fill holes and cracks with metal solder, using gas torches.
- Position and align auxiliary parts in jigs and join parts, using solder and blowtorches.
- Form concavities in bottoms of articles to improve stability, using tracing punches and hammers.
- Peen edges of scratches or holes to repair defects, using peening hammers.
- Strike articles with small tools, or punch them with hammers, to indent them or restore embossing.
- Hammer out dents and bulges, selecting and using hammers and dollies with heads that correspond in curvature to article surfaces.
||Solderers and Brazers
- 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.
- Make repairs, such as enlarging or reducing ring sizes, soldering pieces of jewelry together, and replacing broken clasps and mountings.
- Cut, shape, and smooth gemstones, pearls, and metal pieces, using abrasives, grinding stones, and power and hand tools.
- Soften metal to be used in designs by heating it with a gas torch and shape it, using hammers and dies.
- Burn grooves or crevices in molds in order to correct defects, using soldering guns.
||Welders, Cutters, and Welder Fitters
- Cut, contour, and bevel metal plates and structural shapes to dimensions as specified by blueprints, layouts, work orders, and templates, using powered saws, hand shears, or chipping knives.
- Hammer out bulges or bends in metal workpieces.
- Operate brazing and soldering equipment.
||Model Makers, Metal and Plastic
- Cut, shape, and form metal parts, using lathes, power saws, snips, power brakes and shears, files, and mallets.
- Wire and solder electrical and electronic connections and components.
