||Welders, Cutters, and Welder Fitters
- Weld components in flat, vertical, or overhead positions.
- Recognize, set up, and operate hand and power tools common to the welding trade, such as shielded metal arc and gas metal arc welding equipment.
- Weld separately or in combination, using aluminum, stainless steel, cast iron, and other alloys.
- Clamp, hold, tack-weld, heat-bend, grind or bolt component parts to obtain required configurations and positions for welding.
- Select and install torches, torch tips, filler rods, and flux, according to welding chart specifications or types and thicknesses of metals.
- Ignite torches or start power supplies and strike arcs by touching electrodes to metals being welded, completing electrical circuits.
- Operate manual or semi-automatic welding equipment to fuse metal segments, using processes such as gas tungsten arc, gas metal arc, flux-cored arc, plasma arc, shielded metal arc, resistance welding, and submerged arc welding.
- Guide and direct flames or electrodes on or across workpieces to straighten, bend, melt, or build up metal.
- Join parts such as beams and steel reinforcing rods in buildings, bridges, and highways, bolting and riveting as necessary.
- Gouge metals, using the air-arc gouging process.
||Welding, Soldering, and Brazing Machine Setters, Operators, and Tenders
- Set up, operate, or tend welding machines that join or bond components to fabricate metal products or assemblies.
- Correct problems by adjusting controls or by stopping machines and opening holding devices.
- Tend auxiliary equipment used in welding processes.
- Start, monitor, and adjust robotic welding production lines.
- Assemble machines, and bolt, weld, rivet, or otherwise fasten them to foundation or other structures, using hand tools and power tools.
- Lay out mounting holes, using measuring instruments, and drill holes with power drill.
- Weld, repair, and fabricate equipment or machinery.
||Gem and Diamond Workers
- Regulate the speed of revolutions and reciprocating actions of drilling mechanisms.
- Regrind drill points, and advance drill cutting points according to specifications for channel depths and shapes.
||Electrical and Electronic Equipment Assemblers
- Assemble electrical or electronic systems or support structures and install components, units, subassemblies, wiring, or assembly casings, using rivets, bolts, soldering or micro-welding equipment.
- Drill or tap holes in specified equipment locations to mount control units or to provide openings for elements, wiring, or instruments.
