Welders, Cutters, and Welder Fitters

<ul><li>Weld components in flat, vertical, or overhead positions.</li><li>Operate safety equipment and use safe work habits.</li><li>Lay out, position, align, and secure parts and assemblies prior to assembly, using straightedges, combination squares, calipers, and rulers.</li><li>Examine workpieces for defects and measure workpieces with straightedges or templates to ensure conformance with specifications.</li><li>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.</li><li>Select and install torches, torch tips, filler rods, and flux, according to welding chart specifications or types and thicknesses of metals.</li><li>Clamp, hold, tack-weld, heat-bend, grind or bolt component parts to obtain required configurations and positions for welding.</li><li>Weld separately or in combination, using aluminum, stainless steel, cast iron, and other alloys.</li><li>Ignite torches or start power supplies and strike arcs by touching electrodes to metals being welded, completing electrical circuits.</li><li>Connect and turn regulator valves to activate and adjust gas flow and pressure so that desired flames are obtained.</li><li>Determine required equipment and welding methods, applying knowledge of metallurgy, geometry, and welding techniques.</li><li>Mark or tag material with proper job number, piece marks, and other identifying marks as required.</li><li>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.</li><li>Monitor the fitting, burning, and welding processes to avoid overheating of parts or warping, shrinking, distortion, or expansion of material.</li><li>Analyze engineering drawings, blueprints, specifications, sketches, work orders, and material safety data sheets to plan layout, assembly, and welding operations.</li><li>Prepare all material surfaces to be welded, ensuring that there is no loose or thick scale, slag, rust, moisture, grease, or other foreign matter.</li><li>Remove rough spots from workpieces, using portable grinders, hand files, or scrapers.</li><li>Chip or grind off excess weld, slag, or spatter, using hand scrapers or power chippers, portable grinders, or arc-cutting equipment.</li><li>Preheat workpieces prior to welding or bending, using torches or heating furnaces.</li><li>Position and secure workpieces, using hoists, cranes, wire, and banding machines or hand tools.</li><li>Guide and direct flames or electrodes on or across workpieces to straighten, bend, melt, or build up metal.</li><li>Develop templates and models for welding projects, using mathematical calculations based on blueprint information.</li><li>Detect faulty operation of equipment or defective materials and notify supervisors.</li><li>Clean or degrease parts, using wire brushes, portable grinders, or chemical baths.</li><li>Repair products by dismantling, straightening, reshaping, and reassembling parts, using cutting torches, straightening presses, and hand tools.</li><li>Fill holes, and increase the size of metal parts.</li><li>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.</li><li>Check grooves, angles, or gap allowances, using micrometers, calipers, and precision measuring instruments.</li><li>Operate metal shaping, straightening, and bending machines, such as brakes and shears.</li><li>Set up and use ladders and scaffolding as necessary to complete work.</li><li>Dismantle metal assemblies or cut scrap metal, using thermal-cutting equipment, such as flame-cutting torches or plasma-arc equipment.</li><li>Hammer out bulges or bends in metal workpieces.</li></ul>
