||Welders, Cutters, and Welder Fitters
- Weld components in flat, vertical, or overhead positions.
- Lay out, position, align, and secure parts and assemblies prior to assembly, using straightedges, combination squares, calipers, and rulers.
- 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.
||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.
- 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.
||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.
||Layout Workers, Metal and Plastic
- Fit and align fabricated parts to be welded or assembled.
- Locate center lines and verify template positions, using measuring instruments such as gauge blocks, height gauges, and dial indicators.
- Assemble machines, and bolt, weld, rivet, or otherwise fasten them to foundation or other structures, using hand tools and power tools.
- Weld, repair, and fabricate equipment or machinery.
