Job Overview

The Robotic Welding Engineer supports heavy fabrication manufacturing operations by developing, programming, supporting, and continuously improving robotic MIG/MAG welding processes for mild steel weldments. This position provides technical expertise for robotic weld systems, weld controls, tooling and fixture performance, weld procedure compliance, equipment reliability, technician support, and production troubleshooting. The role supports safety, quality, delivery, and cost objectives by maintaining stable, repeatable welding processes and implementing improvements that reduce downtime, rework, and process variation.

Key Job Responsibilities

Develop, program, and optimize robotic MIG/MAG welding systems for mild steel heavy fabrication, including robot paths, weld schedules, touch sensing, seam tracking, torch angles, travel speeds, shielding gas, wire selection, and process parameters.

Troubleshoot robotic weld issues related to programming, weld controls, fixturing, part fit-up, consumables, equipment condition, weld quality, and process variation. Lead root cause analysis and implement short- and long-term corrective actions.

Maintain welding systems to ensure manufacturing activities remain within specifications, including applicable WPS requirements, quality standards, process controls, KOM-MICs, and internal production requirements.

Support and monitor weld technicians by assisting with daily priorities, troubleshooting, training, and development from a MIG/MAG welding and robotic process perspective.

Partner with maintenance and production to support corrective maintenance activities, PM scheduling, spare parts readiness, robotic weld cell uptime, equipment reliability, and responsible equipment ownership.

Support new product introduction, engineering changes, tooling changes, and process launches by reviewing weld access, fixture repeatability, robot reach, cycle time, safety, manufacturability, and process documentation.

Collect, track, and analyze downtime, weld defect, rework, and process performance data. Recommend process improvements, automation updates, tooling improvements, and capital projects that improve safety, quality, delivery, or cost.

Support internal and external audits by providing welding process information, documentation, and evidence related to ISO 9001, customer standards, and company procedures as applicable.

 

Qualifications/Requirements

Bachelor's degree in Welding Engineering, Manufacturing Engineering, Mechanical Engineering, Electrical Technology, or a related technical field is preferred. Equivalent technical education and directly related welding/robotics experience may be considered.

Strong knowledge of MIG/MAG welding processes for mild steel, including weld parameters, consumables, shielding gas, weld defects, corrective actions, and welding system controls.

Common programming knowledge of robotics and weld controls for mild steel heavy fabrication applications. Experience with Komatsu, Fanuc, ABB, Yaskawa/Motoman, Panasonic, or similar robotic platforms is preferred.

Knowledge of heavy fabrication equipment, fixtures, tooling, weld symbols, WPS requirements, engineering drawings, and manufacturing process documentation.

Ability to evaluate fixture repeatability, part fit-up, weld access, torch clearance, cycle time, weld quality, process stability, and manufacturability in a production environment.

Experience supporting weld technicians, maintenance activities, PM scheduling, equipment troubleshooting, production downtime response, and vendor communication for software, hardware, and welding system issues.

Computer skills including Microsoft Office are required. CAD experience, offline robot programming, simulation software, SAP, or maintenance/work order systems are helpful.

Must be able to communicate effectively with management, engineering, production associates, weld technicians, maintenance, quality, safety, suppliers, vendors, and auditors.

Additional Information

 

Preferred Qualifications:

Experience in heavy equipment, structural fabrication, or large mild steel weldment manufacturing.

Knowledge of AWS D1.1 or similar welding codes, weld procedure development, and weld inspection expectations.

Experience with robotic MIG/MAG weld cell launches, weld control systems, automation improvement projects, fixture design reviews, or capital equipment installation.

 

This position is focused on heavy fabrication and mild steel robotic MIG/MAG welding; resistance spot welding, projection welding, and aluminum welding are not primary responsibilities for this role.

Occasional support outside normal business hours may be required based on production needs, equipment downtime, launches, audits, or urgent quality issues.

Regular shop floor presence is expected to support production, troubleshoot robotic MIG/MAG welding equipment, observe weld processes, assist weld technicians, and work directly with operators, maintenance, quality, and engineering.
