- Advise on welding process selection, filler metals, and joint designs based on material needs.
- Provide design input for weldability, considering factors like accessibility and distortion.
- Support welded hardware throughout its lifecycle, from prototyping to final inspection.
- Collaborate with welders and suppliers to establish consistent, high-quality fabrication.
- Create manufacturing instructions, process controls, and inspection criteria.
- Plan and execute weld qualification, including destructive and nondestructive testing.
- Review weld documentation, inspection results, and material certifications for compliance.
- Lead investigations into weld defects and fabrication issues.
- Develop repair procedures and provide technical disposition for nonconformances.
- Work with various engineering teams to ensure welded assemblies meet all requirements.
- Assist in selecting and overseeing welding suppliers and fabrication partners.
- Promote a strong culture of safety, quality, and continuous improvement.
Requirements
- Bachelor's degree in Welding Engineering, Materials Science, Mechanical Engineering, or a related field.
- At least 2 years of professional experience in welding engineering or welded hardware manufacturing.
- Familiarity with common fusion welding processes like GTAW, GMAW, PAW, laser, or electron beam welding.
- Experience in developing or supporting welding procedures and welder qualifications.
- Understanding of welding metallurgy, including heat-affected zones, solidification, and common defects.
- Ability to interpret engineering drawings, weld symbols, and material specifications.
- Knowledge of destructive and nondestructive testing methods for weld quality.
- Capable of hands-on work with production staff and resolving manufacturing challenges independently.
Nice to have
- 3+ years of welding engineering experience in aerospace, nuclear, pressure vessel, power generation, or defense.
- Experience welding stainless steels, nickel-based superalloys, or dissimilar metals.
- Knowledge of welding and fabrication codes such as ASME Section IX or AWS D17.1.
- Experience with pressure-boundary, high-temperature, or leak-tight welded assemblies.
- Familiarity with advanced welding processes like automated orbital GTAW or additive repair.
- Experience developing weld fixtures, tooling, and purge systems.
- Experience with weld inspection methods including visual, dye penetrant, or radiographic.
- Familiarity with post-weld heat treatment, cleaning, and passivation.
- Experience conducting weld failure investigations using metallography or mechanical testing.
- Certified Welding Inspector (CWI) or International Welding Engineer (IWE) qualification.
