Emerging
Entry / Apprentice
  1. Work orders and production schedules — read and interpret under direct supervision to identify basic job specifications on the shop floor.
  2. Welding machine controls and settings — identify and distinguish under guidance before operating equipment on a fabrication line.
  3. Metal workpieces and completed assemblies — visually inspect for obvious surface defects under the direction of a lead operator.
  4. Hand-operated grinders and cutters — use to prepare metal surfaces according to step-by-step instructions in a production setting.
  5. Torch tips, alloys, and flux materials — select from labeled inventory following a data chart provided by a supervisor.
  6. Parts and components to be bonded — lay out and fit according to templates or diagrams under close oversight on the production floor.
  7. Basic measuring devices such as calipers and gauges — apply to check workpiece dimensions against stated specifications with supervisor verification.
  8. Operational information and machine run data — record on standardized production report forms under supervisor direction.
  9. Machine holding devices and clamps — open and close safely following lockout/tagout procedures as instructed by a lead technician.
  10. Active listening skills — demonstrate by following verbal instructions from lead operators and asking clarifying questions during shift briefings.
Developing
Mid-level / Established
  1. Blueprints and work orders — read and translate into machine setup parameters with minimal oversight on a mid-volume fabrication line.
  2. Welding machines for joining metal assemblies — set up, operate, and tend routinely across common metal types in a production environment.
  3. Measuring and testing devices — apply independently to inspect completed workpieces and confirm dimensional conformance to specifications.
  4. Machine controls and operating parameters — adjust to correct process deviations when weld quality or output falls outside acceptable limits.
  5. Torch tips, wire gauges, and flux selections — choose according to metal thickness and job records without requiring supervisor approval for standard applications.
  6. Production report forms and shift logs — complete accurately and consistently, capturing key operational data for supervisory review.
  7. Metal surfaces — prepare using grinders, drills, and cutters with consistent technique to meet surface quality requirements before bonding.
  8. Component fit-up and part alignment — execute with production measurements calculated independently for familiar assembly configurations.
  9. Minor machine stoppages and holding-device errors — identify root cause and resolve by adjusting controls or resetting the machine during routine production shifts.
  10. Industrial control software interfaces — navigate to monitor machine status and input setup parameters within established production workflows.
Proficient
Senior / Expert IC
  1. Complex blueprints and multi-step production schedules — interpret autonomously and convert into precise machine configurations across a full range of metal products.
  2. Welding, soldering, and brazing machines — set up and operate across the full scope of available equipment types, handling non-standard alloys and irregular workpiece geometries.
  3. Measurement and testing protocols — apply systematically to verify weld integrity, dimensional accuracy, and surface quality against tight engineering tolerances.
  4. Process deviations and recurring quality defects — diagnose through critical analysis of machine settings, material properties, and environmental factors, then implement corrective actions.
  5. Material and consumable selection — determine optimal torch tips, alloys, coil, tubing, and wire for uncommon or challenging metal combinations using technical records and deductive reasoning.
  6. Part layout, fit, and connection sequences — plan and execute independently for complex assemblies, including calculating custom production measurements without reference templates.
  7. Surface preparation procedures — perform and verify across varied metal conditions, selecting the appropriate hand-operated tool and technique for each workpiece type.
  8. ERP and spreadsheet software — use to track production output, material consumption, and machine performance data, supporting accurate reporting across shifts.
  9. Problem sensitivity on the production line — detect subtle early indicators of equipment wear, weld discontinuities, or material inconsistencies before they result in nonconforming output.
  10. Operational knowledge — share with newer operators through on-the-spot coaching and demonstration during live production runs.
Advanced
Lead / Principal / Executive
  1. Machine setup standards and operational procedures — develop and formalize for the welding and brazing department to ensure consistent quality and safety across all shifts.
  2. Production schedules and workflow priorities — coordinate at a departmental level, balancing machine capacity, material availability, and customer deadlines.
  3. Quality inspection criteria and measurement protocols — establish and update to reflect engineering specification changes, communicating requirements clearly to all operators.
  4. Recurring process failures and systemic quality issues — lead root-cause investigations using complex problem-solving methods, implementing lasting corrective and preventive solutions.
  5. Operator skill development programs — design and deliver, using real production scenarios to build competency in machine operation, blueprint reading, and quality inspection.
  6. Material selection standards and consumable specifications — author for the facility, incorporating data chart updates and new alloy introductions into documented work instructions.
  7. ERP and industrial control software configurations — oversee and guide, ensuring machine data, production reports, and inventory records align across systems.
  8. Safety and cautiousness culture — champion across the production team by modeling lockout/tagout compliance, hazard identification, and incident-reporting best practices.
  9. Cross-functional communication — lead between production, engineering, and management teams to translate technical welding requirements into actionable production plans.
  10. Departmental performance metrics including throughput, scrap rate, and machine utilization — monitor, interpret, and present to plant leadership to drive continuous improvement decisions.
