Details for Welders, Cutters, and Welder Fitters


Description

Use hand-welding or flame-cutting equipment to weld or join metal components or to fill holes, indentations, or seams of fabricated metal products.

Tasks

  • Operate safety equipment, and use safe work habits.
  • Weld components in flat, vertical, or overhead positions.
  • Ignite torches or start power supplies and strike arcs by touching electrodes to metals being welded, completing electrical circuits.
  • Clamp, hold, tack-weld, heat-bend, grind and/or bolt component parts to obtain required configurations and positions for welding.
  • Detect faulty operation of equipment and/or defective materials, and notify supervisors.
  • 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.
  • Monitor the fitting, burning, and welding processes to avoid overheating of parts or warping, shrinking, distortion, or expansion of material.
  • Examine workpieces for defects, and measure workpieces 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.
  • Lay out, position, align, and secure parts and assemblies prior to assembly, using straightedges, combination squares, calipers, and rulers.
  • Chip or grind off excess weld, slag, or spatter, using hand scrapers or power chippers, portable grinders, or arc-cutting equipment.
  • Analyze engineering drawings, blueprints, specifications, sketches, work orders, and material safety data sheets to plan layout, assembly, and welding operations.
  • Connect and turn regulator valves to activate and adjust gas flow and pressure so that desired flames are obtained.
  • Weld separately or in combination, using aluminum, stainless steel, cast iron, and other alloys.
  • Determine required equipment and welding methods, applying knowledge of metallurgy, geometry, and welding techniques.
  • Mark and/or tag material with proper job number, piece marks, and other identifying marks as required.
  • Prepare all material surfaces to be welded, ensuring that there is no loose or thick scale, slag, rust, moisture, grease, or other foreign matter.
  • Select and install torches, torch tips, filler rods, and flux, according to welding chart specifications, or types and thicknesses of metals.
  • Remove rough spots from workpieces, using portable grinders, hand files, or scrapers.
  • Position and secure workpieces, using hoists, cranes, wire, and banding machines or hand tools.
  • Clean or degrease parts, using wire brushes, portable grinders, or chemical baths.
  • 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.
  • Dismantle metal assemblies or cut scrap metal, using thermal-cutting equipment such as flame-cutting torches or plasma-arc equipment.
  • Check grooves, angles, or gap allowances, using micrometers, calipers, and precision measuring instruments.
  • Signal crane operators to move large workpieces.
  • 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.
  • Estimate materials needed for production and manufacturing; maintain required stocks of materials.
  • Develop templates and models for welding projects, using mathematical calculations based on blueprint information.
  • Cut metal plates and structural shapes to dimensions, and contour and bevel as specified by blueprints, layouts, work orders, and templates, using powered saws, hand shears, or chipping knives.
  • Preheat workpieces prior to welding or bending, using torches or heating furnaces.
  • Use fire suppression methods in industrial emergencies.
  • Melt lead bars, wire, or scrap to add lead to joints or to extrude melted scrap into reusable form.
  • Set up and use ladders and scaffolding as necessary to complete work.
  • Join parts such as beams and steel reinforcing rods in buildings, bridges, and highways, bolting and riveting as necessary.
  • Hammer out bulges or bends in metal workpieces.
  • Mix and apply protective coatings to products.
  • Operate metal shaping, straightening, and bending machines such as brakes and shears.
  • Operate brazing and soldering equipment.

Interests

  • Realistic - Realistic occupations frequently involve work activities that include practical, hands-on problems and solutions. They often deal with plants, animals, and real-world materials like wood, tools, and machinery. Many of the occupations require working outside, and do not involve a lot of paperwork or working closely with others.

Education, Training, Experience

  • Education - Most occupations in this zone require training in vocational schools, related on-the-job experience, or an associate's degree.
  • Training - Employees in these occupations usually need one or two years of training involving both on-the-job experience and informal training with experienced workers. A recognized apprenticeship program may be associated with these occupations.
  • Experience - Previous work-related skill, knowledge, or experience is required for these occupations. For example, an electrician must have completed three or four years of apprenticeship or several years of vocational training, and often must have passed a licensing exam, in order to perform the job.

Knowledge

  • English Language - Knowledge of the structure and content of the English language including the meaning and spelling of words, rules of composition, and grammar.
  • Mathematics - Knowledge of arithmetic, algebra, geometry, calculus, statistics, and their applications.
  • Engineering and Technology - Knowledge of the practical application of engineering science and technology. This includes applying principles, techniques, procedures, and equipment to the design and production of various goods and services.
  • Design - Knowledge of design techniques, tools, and principles involved in production of precision technical plans, blueprints, drawings, and models.
  • Mechanical - Knowledge of machines and tools, including their designs, uses, repair, and maintenance.
