Welder (Production)

Develop templates and models for welding projects, using mathematical calculations based on blueprint information.

Clamp, hold, tack-weld, heat-bend, grind or bolt component parts to obtain required configurations and positions for welding.

Set up and use ladders and scaffolding as necessary to complete work.

Connect and turn regulator valves to activate and adjust gas flow and pressure so that desired flames are obtained.

Fill holes, and increase the size of metal parts.

Dismantle metal assemblies or cut scrap metal, using thermal-cutting equipment, such as flame-cutting torches or plasma-arc equipment.

Select and install torches, torch tips, filler rods, and flux, according to welding chart specifications or types and thicknesses of metals.

Check grooves, angles, or gap allowances, using micrometers, calipers, and precision measuring instruments.

Determine required equipment and welding methods, applying knowledge of metallurgy, geometry, and welding techniques.

Gouge metals, using the air-arc gouging process.

Guide and direct flames or electrodes on or across workpieces to straighten, bend, melt, or build up metal.

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.

Melt lead bars, wire, or scrap to add lead to joints or to extrude melted scrap into reusable form.

Lay out, position, align, and secure parts and assemblies prior to assembly, using straightedges, combination squares, calipers, and rulers.

Repair products by dismantling, straightening, reshaping, and reassembling parts, using cutting torches, straightening presses, and hand tools.

Position and secure workpieces, using hoists, cranes, wire, and banding machines or hand tools.

Prepare all material surfaces to be welded, ensuring that there is no loose or thick scale, slag, rust, moisture, grease, or other foreign matter.

Signal crane operators to move large workpieces.

Operate metal shaping, straightening, and bending machines, such as brakes and shears.

Preheat workpieces prior to welding or bending, using torches or heating furnaces.

Analyze engineering drawings, blueprints, specifications, sketches, work orders, and material safety data sheets to plan layout, assembly, and welding operations.

Examine workpieces for defects and measure workpieces with straightedges or templates to ensure conformance with specifications.

Monitor the fitting, burning, and welding processes to avoid overheating of parts or warping, shrinking, distortion, or expansion of material.

Hammer out bulges or bends in metal workpieces.

Chip or grind off excess weld, slag, or spatter, using hand scrapers or power chippers, portable grinders, or arc-cutting equipment.

Ignite torches or start power supplies and strike arcs by touching electrodes to metals being welded, completing electrical circuits.

Clean or degrease parts, using wire brushes, portable grinders, or chemical baths.

Operate brazing and soldering equipment.

Mix and apply protective coatings to products.

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.

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.

Detect faulty operation of equipment or defective materials and notify supervisors.

Mark or tag material with proper job number, piece marks, and other identifying marks as required.

Weld separately or in combination, using aluminum, stainless steel, cast iron, and other alloys.

Remove rough spots from workpieces, using portable grinders, hand files, or scrapers.

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.
