Core Responsibilities

Primary Functions

Program, teach, and optimize industrial robot welding cells (FANUC, ABB, KUKA or similar) including path teaching, weld sequencing, and motion profiles to ensure consistent, high-quality welds that meet engineering drawings and weld procedures.
Set up, align, and fixture parts in robotic cells and welding stations, verifying part fit-up and tolerances prior to welding to reduce scrap and rework.
Configure and adjust welding parameters (amperage, voltage, wire feed speed, travel speed, shielding gas, and pulse settings) for MIG, TIG, and arc processes to achieve specified weld penetration, bead appearance, and non-destructive test acceptance.
Load, unload, and inspect production parts using dimensional gauges, calipers, and visual criteria; document acceptance or reject condition and escalate nonconformances to supervision.
Perform teach pendant programming edits, create and modify robot programs, and implement macro routines to increase throughput, minimize cycle time, and improve weld quality.
Conduct routine preventive maintenance and mechanical/electrical checks on welding robots, wire feeders, torch assemblies, fume extraction systems, and conveyors to prevent unplanned downtime.
Troubleshoot robot faults, torch malfunctions, wire feed issues, and welding parameter inconsistencies using systematic diagnostics, electrical schematics, and PLC/robot error codes.
Collaborate with process engineers to develop and validate welding procedures (WPS/PQR) and to implement process controls that maintain weld integrity and reduce variability.
Calibrate and maintain welding equipment and measuring tools (contactors, pressure regulators, flow meters, weld gauges) and ensure all tooling is clean, safe, and within specification.
Implement and follow lockout/tagout (LOTO), confined space, and welding PPE protocols; actively participate in health & safety meetings and corrective action plans.
Monitor production metrics such as first-pass yield, cycle time, uptime, and scrap rate; recommend and implement corrective actions to improve KPIs.
Train and mentor entry-level operators on robotic cell operation, safe torch handling, program changes, and best practices for consistent production output.
Prepare and communicate shift changeover reports including outstanding issues, machine status, pending maintenance, and improvement opportunities to maintain continuity across shifts.
Test weld samples and coordinate NDT (ultrasonic, dye-penetrant, visual) and destructive testing as required; interpret results and recommend process adjustments to meet quality standards.
Manage inventory of welding consumables (wire, contact tips, nozzles, shielding gas) and request replacement parts to prevent stockouts and production downtime.
Modify and install end-of-arm tooling (EOAT), weld fixtures, and positioners to accommodate new part geometries and transition kits for quick changeover of production runs.
Work with automation engineers to pilot new fixtures, cell layouts, sensors, and vision systems (arc sensing, seam tracking) to enhance automation and reduce rework.
Document program revisions, setup sheets, routings, and equipment maintenance logs in the shop floor system or MES to ensure traceability and reproducibility.
Lead root cause analysis for recurring weld defects or machine failures, develop corrective actions, and follow through to verify corrective measures are effective.
Collaborate with supply chain and maintenance to coordinate downtime windows for major repairs, upgrades, or robot retooling while minimizing impact to production.
Participate in continuous improvement initiatives (Kaizen, 5S, Lean Manufacturing) to streamline welding cell operations, reduce SMED times, and improve workplace organization.
Ensure compliance with all customer-specific welding requirements, industry codes (AWS, ISO), and company quality management systems; prepare documentation for audits and customer visits.
Support new product launches by participating in pilot runs, cycle time studies, and production readiness reviews to ensure robotic welding processes are stable and scalable.

Secondary Functions

Assist engineering and manufacturing with process validations, capability studies, and creation of standard operating procedures (SOPs) for robotic welding operations.
Provide input to capital expenditure (capex) requests for new robotic equipment, tooling upgrades, or automation investments based on observed production needs.
Support cross-training programs and prepare training materials to broaden operator skill sets and create staffing flexibility across shifts.
Help maintain a clean and safe work environment by participating in daily 5S activities, housekeeping, and environmental compliance related to welding fumes and waste.
Support scheduling and coordination with cell leaders and production planners to prioritize jobs, manage changeovers, and meet customer delivery dates.
