WELDER

Use hand-welding or flame-cutting equipment to weld or join metal components or to fill holes, indentations, or seams of fabricated metal products. Weld per AISC D1.1 per drawings in a quality and productive manner.

• Weld components in flat, vertical, or overhead positions.
• Operate safety equipment and use safe work habits.
• Lay out, position, align, and secure parts and assemblies prior to assembly, using straightedges, combination squares, calipers, and rulers.
• Examine work pieces for defects and measure work pieces with straightedges or templates to ensure conformance with specifications.
• 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.
• Connect and turn regulator valves to activate and adjust gas flow and pressure so that desired flames are obtained.
• Determine required equipment and welding methods, applying knowledge of metallurgy, geometry, and welding techniques.
• Monitor the fitting, burning, and welding processes to avoid overheating of parts or warping, shrinking, distortion, or expansion of material.
• 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.
• Analyze engineering drawings, blueprints, specifications, sketches, work orders, and material safety data sheets to plan layout, assembly, and welding operations.
• Mark or tag material with proper job number, piece marks, and other identifying marks as required.
• Chip or grind off excess weld, slag, or spatter, using hand scrapers or power chippers, portable grinders, or arc‑cutting equipment.
• Remove rough spots from work pieces, using portable grinders, hand files, or scrapers.
• Prepare all material surfaces to be welded, ensuring that there is no loose or thick scale, slag, rust, moisture, grease, or other foreign matter.
• Preheat work pieces prior to welding or bending, using torches or heating furnaces.
• Develop templates and models for welding projects, using mathematical calculations based on blueprint information.
• Position and secure work pieces, using hoists, cranes, wire, and banding machines or hand tools.
• Guide and direct flames or electrodes on or across work pieces to straighten, bend, melt, or build up metal.
• Detect faulty operation of equipment or defective materials and notify supervisors.
• Clean or degrease parts, using wire brushes, portable grinders, or chemical baths.
• 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.
• Repair products by dismantling, straightening, reshaping, and reassembling parts, using cutting torches, straightening presses, and hand tools.
• Fill holes and increase the size of metal parts.
• Check grooves, angles, or gap allowances, using micrometers, calipers, and precision measuring instruments.
• Operate metal shaping, straightening, and bending machines, such as brakes and shears.
• Set up and use ladders and scaffolding as necessary to complete work.
• Hammer out bulges or bends in metal work pieces.
• Dismantle metal assemblies or cut scrap metal, using thermal‑cutting equipment such as flame‑cutting torches or plasma‑arc equipment.
• Signal crane operators to move large work pieces.
• Use fire suppression methods in industrial emergencies.
• Estimate materials needed for production and manufacturing and maintain required stocks of materials.
• 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.
• Mix and apply protective coatings to products.
• Operate brazing and soldering equipment.
