Core Responsibilities

Primary Functions

Read, interpret and apply engineering drawings, welding symbols and welding procedure specifications (WPS) to accurately set up and execute welds that meet dimensional tolerances, fit-up requirements, and acceptance criteria.
Perform high-quality MIG (GMAW) welding on a variety of ferrous and non-ferrous materials, adjusting machine parameters, wire feed speeds, and gas flow to control penetration and bead appearance.
Execute TIG (GTAW) welds for precision joints and critical assemblies, maintaining appropriate tungsten selection, gas purity, amperage control and heat input to prevent warping and contamination.
Carry out SMAW (stick) welding for structural and maintenance applications, including electrode selection, proper arc strike/strike-off technique, and adherence to preheat/post-heat instructions when specified.
Operate flux-cored arc welding (FCAW) equipment to join thick sections and heavy assemblies while monitoring slag control, spatter reduction and weld profile.
Prepare parts for welding through layout, tack welding, grinding, beveling, and fit-up, ensuring correct root gaps, alignment and clamp-up to minimize rework.
Set up and operate welding positioners, manipulators, and fixtures to maintain weld consistency and ergonomics across repetitive production runs.
Maintain welding machines, torches, cables, and gas systems by performing daily preventive checks, replacing consumables, and logging maintenance actions to prevent downtime.
Perform in-process inspection and non-destructive examination support including visual inspection, dye penetrant (PT), magnetic particle testing (MT) or assisting with ultrasonic (UT) testing as required to verify weld integrity.
Document weld parameters, material lot numbers, WPS references, and inspection results in production travelers, weld logs or electronic quality systems to maintain traceability and compliance with customer requirements.
Follow and enforce site safety rules, lockout/tagout, PPE requirements, and safe handling of compressed gases, fumes and hot work permits to protect self and co-workers.
Troubleshoot welding defects such as porosity, lack of fusion, cracking and distortion by diagnosing root causes and implementing corrective actions or process changes.
Support first-article builds and prototype welds by collaborating with engineers to qualify WPS changes, perform sample test coupons, and iterate until production-ready procedures are established.
Meet daily production quotas and takt times while balancing quality standards by managing time, optimizing weld sequences, and coordinating with material handlers and QA inspectors.
Train and mentor junior welders and apprentices on best practices, shop standards, welding techniques and quality expectations to raise overall team capability.
Operate handheld cutting tools, plasma cutters or oxy-fuel torches for part preparation and trim operations ensuring accurate edge conditions for weld joints.
Apply finishing operations such as grinding, blending and touch-up welding to achieve specified surface finish, dimensional tolerances and paint/coat readiness.
Participate in continuous improvement and lean manufacturing initiatives by suggesting process improvements, fixture redesigns and waste reduction ideas that increase throughput and reduce rework.
Adhere to customer-specific quality systems (ISO 9001, ASME Section IX, AWS D1.1, etc.), complete required documentation, and support internal/external audits with factual evidence of compliance.
Coordinate with production planning to identify material shortages, tooling needs and schedule impacts; provide realistic time estimates and escalate issues to supervisors when required.
Safely move and stage heavy components using forklifts, hoists and rigging gear, following load charts and rigging procedures to prevent damage to parts and injury.
Maintain a clean, organized work area and ensure all consumables and spare parts are stocked, labeled and accessible to support uninterrupted production flow.
Implement best practice heat control strategies including preheat, interpass temperature control and post-weld heat treatment (PWHT) coordination to meet metallurgical and stress-relief requirements.
Demonstrate and maintain welding certifications as required by the employer or customer (e.g., AWS welder qualification) and participate in requalification tests on schedule.

Secondary Functions

Assist engineering and quality teams with root-cause analysis by providing hands-on observations from the shop floor and participating in corrective action implementation.
Support kaizen events and production line balancing by offering practical insights on cycle time reductions, fixture improvements and ergonomic adjustments.
Cross-train on adjacent fabrication operations (cutting, CNC plasma, bending) to provide production flexibility during peak workloads or absenteeism.
Help maintain parts inventory accuracy by labeling completed assemblies, returning scrap to designated containers and reporting discrepancies to warehouse personnel.
Participate in workstation tool calibration checks (weld gauges, calipers, thermometers) and ensure measurement tools are within tolerance.
Provide input to procurement on preferred consumables, electrode types and shielding gases based on shop experience to help optimize cost and quality.
Assist in collecting data for weld process capability studies and SPC charts to support continuous improvement and quality assurance metrics.
Facilitate safe handover between shifts by completing clear shift reports, documenting ongoing work, and briefing the next shift on critical issues or pending inspections.
Support customer visit preparation and demonstration builds by ensuring show-piece welds meet visual and dimensional expectations.
Participate in mentorship programs and training class development to standardize best practices and reduce onboarding time for new hires.
