Essential Responsibilities

Electron Beam Welding Operations

• Set up and operate Electron Beam (EB) welding equipment in vacuum and partial-vacuum environments.
• Program and adjust welding parameters including beam current, accelerating voltage, focus settings, and travel speed.
• Align and calibrate electron beams using optical, digital, and precision measurement systems.
• Monitor welding cycles to ensure process stability, vacuum integrity, and adherence to quality requirements.
• Perform welds on high-value, tight-tolerance components in accordance with engineering specifications.

Tooling, Setup & Fixture Fabrication

• Interpret engineering drawings, blueprints, CAD models, and weld specifications.
• Design, assemble, and modify fixtures, tooling, and work-holding devices for complex welded assemblies.
• Perform precision part alignment, fit-up, and setup using calipers, micrometers, indicators, and other measuring equipment.
• Clean and prepare materials and components to meet vacuum welding cleanliness standards.

Quality & Inspection

• Conduct visual inspections of completed welds and prepare parts for non-destructive testing (NDT).
• Verify dimensional and quality requirements are met throughout the manufacturing process.
• Maintain accurate weld documentation, process records, and traceability requirements.
• Support compliance with applicable aerospace, defense, and customer quality standards.

Equipment Maintenance & Troubleshooting

• Troubleshoot welding equipment issues including vacuum leaks, arc-outs, beam instability, and filament failures.
• Perform routine preventative maintenance on EB welding systems, vacuum chambers, pumps, and related equipment.
• Replace consumables such as filaments and perform basic machine calibration activities.
• Assist engineering and manufacturing teams in process improvements and root cause investigations.

Qualifications

Required

• 2+ years of experience operating Electron Beam (EB) welding systems or comparable advanced welding equipment.
• Experience reading and interpreting engineering drawings, GD&T, and manufacturing specifications.
• Strong understanding of welding principles, metallurgy, heat-affected zones (HAZ), and precision fabrication techniques.
• Experience using precision measuring instruments including calipers, micrometers, and indicators.
• Ability to troubleshoot mechanical and process-related equipment issues.
• Basic computer skills and experience working with CNC-controlled equipment.
• Ability to lift up to 50 pounds and stand for extended periods.

Preferred

• Experience with Sciaky, PTR, Leybold, or similar Electron Beam welding systems.
• TIG (GTAW) welding experience for tack welding, fixturing, or repair work.
• Aerospace, defense, nuclear, or other highly regulated manufacturing experience.
• Knowledge of AWS D17.1, NAVSEA, ASME, or similar welding standards.
• Fixture design, tooling fabrication, or Lang Technician experience.
• Non-Destructive Testing (NDT) exposure or certification.
