NASA welding salary in 2026: certifications, processes, and pay by center
The world's largest friction stir welding tool at NASA's Michoud Assembly Facility in New Orleans joins 170-foot-tall aluminum-lithium barrel sections for the SLS core stage, producing welds that must withstand cryogenic propellant temperatures and launch loads exceeding 8.8 million pounds of thrust. Welding technicians supporting NASA programs work across TIG, MIG, friction stir, electron beam, and orbital welding processes on flight hardware that cannot fail.
Here is the complete salary breakdown for welding careers at NASA, which centers hire welders, certifications that matter, and how contractor and civil service paths compare.
Types of welding at NASA
NASA programs use several specialized welding processes, each requiring different skills and commanding different pay premiums:
| Process | Application | Typical Material | Centers Using It |
|---|---|---|---|
| GTAW/TIG | Propellant lines, engine components, pressure vessels | Stainless steel, Inconel, titanium | All centers |
| GMAW/MIG | Ground support equipment, structural fabrication | Carbon steel, aluminum | KSC, SSC, MSFC |
| Friction Stir Welding (FSW) | SLS core stage barrel panels, large aluminum structures | Aluminum-lithium (Al-Li 2195) | Michoud (MAF) |
| Electron Beam Welding (EBW) | Engine components, precision aerospace joints | Titanium, Inconel, refractory metals | MSFC, GRC |
| Orbital Welding | Propellant system tubing, clean-room piping | Stainless steel, Inconel | KSC, SSC, JSC |
| Laser Welding | Thin-wall structures, additive manufacturing repair | Various aerospace alloys | MSFC, GRC |
TIG welding is the most broadly required skill. Friction stir welding operators at Michoud are among the highest-paid welding technicians in the NASA supply chain due to the specialized training and the criticality of the SLS hardware they produce.
Aerospace welding at NASA operates under far stricter quality standards than commercial or structural welding. Every weld on flight-critical hardware is inspected using X-ray radiography, ultrasonic testing, or dye penetrant inspection. Welders must pass qualification tests for each specific weld procedure (material, thickness, position, process), and qualifications must be maintained through regular retesting. A single defective weld on a propellant tank or pressure vessel could cause catastrophic failure, which means rejection rates, rework standards, and documentation requirements far exceed any commercial welding application.
Salary by experience and specialization
Contractor welding technician salaries
The vast majority of welders supporting NASA programs are employed by contractors. Base salary varies by experience, process specialization, and location:
| Experience Level | General TIG/MIG | Orbital Welding | FSW Operator | EBW Operator |
|---|---|---|---|---|
| Entry (0-2 yr) | $48K-$58K | $52K-$62K | $55K-$65K | $55K-$68K |
| Mid (3-7 yr) | $58K-$72K | $65K-$78K | $68K-$82K | $70K-$85K |
| Senior (8-15 yr) | $72K-$88K | $78K-$95K | $82K-$100K | $85K-$105K |
| Lead/Inspector (15+ yr) | $85K-$100K | $90K-$108K | $95K-$115K | $100K-$120K |
Overtime is common during production surges and launch campaigns. Hourly workers at 1.5x overtime can add $8K-$20K annually to these base figures.
Civil service welding positions (WG scale)
A small number of welders work as NASA civil servants under the Wage Grade (WG) pay system rather than the GS scale. WG pay varies by locality and is based on local prevailing wage surveys:
| WG Grade | Hourly Rate (typical) | Annual Equivalent | Typical Role |
|---|---|---|---|
| WG-8 | $24-$30/hr | $50K-$62K | Welder helper, trainee |
| WG-10 | $28-$36/hr | $58K-$75K | Journey welder |
| WG-11 | $31-$40/hr | $64K-$83K | Senior welder |
| WG-12 | $35-$44/hr | $73K-$92K | Lead welder, welding inspector |
| WL-10/11 | $32-$42/hr | $67K-$87K | Welding supervisor (leader grade) |
Civil service welders receive full federal benefits (FERS pension, TSP matching, FEHB health insurance) which add 30-40% to the value of their compensation compared to base pay alone.
Friction stir welding operators and electron beam welding operators earn the highest base pay among NASA welding technicians. Both processes require extensive training on expensive, specialized equipment. FSW operators at Michoud Assembly Facility are particularly well-compensated because the SLS core stage is the only active production program using large-scale FSW, creating a small but critical labor pool. Orbital welders who can maintain certifications across multiple exotic alloys (Inconel 718, Hastelloy, titanium) also command premium rates.

AWS D17.1 certification is the single most important credential for welders seeking NASA aerospace work. This standard covers fusion welding of aerospace hardware and requires passing practical weld tests on specific materials, positions, and processes. Welders must requalify periodically (typically every 6-12 months) to maintain their certifications.
How to get hired
For contractor positions:
- Build a foundation in TIG welding through a trade school or community college welding program (6-12 month programs are sufficient)
- Obtain AWS D1.1 and D1.2 certifications
- Gain 2-3 years of experience in industrial or manufacturing welding
- Pursue AWS D17.1 aerospace welding certification
- Apply to NASA contractor career sites: Boeing (MAF), Jacobs/Amentum (KSC, SSC), KBR (MSFC), and Syncom Space Services
- Highlight specific alloys you have welded (aluminum, stainless, Inconel, titanium) and positions (all-position TIG is strongly preferred)
For civil service positions:
- Search USAJobs.gov for Wage Grade welding positions (Series 3703 - Welding, or 3705 - Welding Inspection)
- Federal welding positions open less frequently than contractor roles
- Veterans with military welding experience (Navy hull technician, Army 91E welder) receive hiring preference
Military welders, particularly Navy hull technicians (HT) and Seabee steelworkers (SW), have a direct path to NASA welding careers. Military welding training covers many of the same materials and quality standards used in aerospace. Veterans receive 5-point or 10-point preference on USAJobs, and military welding experience counts toward the experience requirements for both contractor and civil service positions. Navy nuclear-qualified welders who have worked on submarine reactor systems are especially valued for their documentation discipline and quality mindset.
Career progression
Welding careers at NASA follow a clear advancement path:
Years 0-3: Welder/Welder Trainee. Learn aerospace-specific procedures, earn initial certifications, and build experience on non-flight or low-criticality hardware.
Years 3-7: Certified Aerospace Welder. Qualified on multiple processes and materials, working on flight hardware. This is where most welders spend the bulk of their careers.
Years 7-12: Senior Welder or Weld Inspector. Lead complex welding tasks, mentor junior welders, or transition into weld inspection (CWI certification). Inspectors typically earn 10-15% more than production welders at the same experience level.
Years 12+: Lead Welder, Welding Supervisor, or NDE Specialist. Manage welding operations, develop weld procedures, or specialize in non-destructive evaluation (radiography, ultrasonic, eddy current). Supervisors can reach $100K-$120K. NDE Level III specialists earn $95K-$130K.
Frequently asked questions
Do I need a college degree to be a welder at NASA?
No. Welding positions do not require a college degree. A high school diploma or GED combined with trade school welding training and AWS certifications is the standard path. Community colleges and technical schools offering AWS-accredited welding programs provide the best preparation. Some employers accept completion of a welding apprenticeship in lieu of formal trade school.
What is the difference between a welding technician and a welding engineer at NASA?
Welding technicians perform the physical welding and are typically WG or hourly contractor employees earning $48K-$105K. Welding engineers (GS or salaried, typically with a BS in welding engineering, materials science, or metallurgy) develop weld procedures, conduct failure analysis, and oversee welding programs. Welding engineers earn $80K-$150K at NASA. The two roles work closely together but have different education requirements and career paths.
How do NASA welding salaries compare to SpaceX or Blue Origin?
SpaceX welders at Starbase and Hawthorne earn $55K-$95K base with equity (RSUs) adding $10K-$25K in value. Blue Origin welders in Huntsville earn similar base rates ($55K-$90K). NASA contractor welders earn comparable base salaries but without equity upside. The tradeoff is that NASA contractor positions typically offer better work-life balance (fewer overtime demands than SpaceX) and more comprehensive benefits packages.
Is friction stir welding hard to learn?
FSW is a machine-operated process, so the skill set is different from manual arc welding. FSW operators program and monitor large CNC-type machines rather than holding a torch. Training takes 3-6 months for experienced welders who already understand metallurgy and quality standards. The challenge is the limited number of training opportunities since only a handful of facilities in the world operate large-scale FSW equipment.
