Details for Welders, Cutters, and Welder Fitters
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 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 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.
- 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 workpieces, 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 workpieces 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 workpieces, using hoists, cranes, wire, and banding machines or hand tools.
- Guide and direct flames or electrodes on or across workpieces 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 workpieces.
- 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 workpieces.
- 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.
- Melt lead bars, wire, or scrap to add lead to joints or to extrude melted scrap into reusable form.
- 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.
- 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.
