Explore Our Welding Processes
Gas Tungsten Arc Welding (GTAW / TIG Welding)
GTAW uses a tungsten electrode and optional filler rod to produce clean, precise welds. Shielding gas protects the molten metal from contamination.
Advantages
- Extremely clean and accurate welds
- Superior control over heat input and penetration
- Ideal for thin-wall components, tight-tolerance joints, and critical welds
Common Materials
- Aluminum
- Titanium
- Magnesium
- Stainless steel
Gas Metal Arc Welding (GMAW / MIG Welding)
GMAW uses a continuous wire electrode to join materials efficiently, making it suitable for higher-volume or thicker-section weldments.
Advantages
- High deposition rates for efficient production
- Reliable, repeatable fusion on thicker components
- Clean process suitable for many industrial applications
Common Materials
- Stainless steel
- Carbon steel
How the Precision Welding Process Works
Step 1 — Joint Evaluation & Method Selection
Our team reviews engineering drawings, material type, joint configuration, and heat-treatment needs to determine the ideal welding process and filler material.
Step 2 — Surface Preparation & Fixturing
Components are cleaned, aligned, and fixtured to ensure consistent weld placement, quality, and repeatability.
Step 3 — Controlled Welding Execution
Certified welders perform welding using calibrated equipment, shielding gases, and precise heat control to ensure fusion quality and metallurgical integrity.
Step 4 — Inspection & Certification
A Certified Welding Inspector (CWI) evaluates weld appearance, penetration, fusion, and overall quality according to applicable standards and codes.

FAQs
MIL maintains a wide range of prime approvals across aerospace and defense OEMs, including major primes that require strict adherence to weld quality, workmanship, and inspection standards.
While approvals vary by program and alloy, MIL routinely supports welding aligned with:
- AMS, AWS, NADCAP, and MIL-STD welding requirements
- Prime-specific weld specifications for aerospace assemblies
- Customer-provided WPS/PQR requirements
To confirm approval for a specific specification or prime, our team can review your drawing or PO and validate compliance before quoting.
Turnaround depends on complexity, part count, and required inspections, but typical lead times are:
- Simple weldments: 1–3 days
- Complex or multi-pass welds: 3–7 days
- Welds requiring NDT (PT, MT, X-ray): 2–5 days additional, depending on method
- Urgent prototype / AOG needs: Rush capacity often available
Certification is completed by a Certified Welding Inspector (CWI) and included with final documentation.
MIL welders have extensive experience with both common and difficult alloys used in aerospace and high-reliability applications, including:
- Aluminum (2000-, 6000-, and 7000-series)
- Titanium (Commercially pure and Ti-6Al-4V)
- Magnesium alloys
- Stainless steels (300 and 400 series, PH grades)
- Carbon steels and alloy steels
Typical thickness range:
- Thin sheet / sensitive parts: down to ~0.020″
- Structural or thick components: up to several inches (GTAW or GMAW depending on deposition needs)
Yes. NDT is one of MIL’s core competencies. We perform:
- Fluorescent Dye Penetrant (FPI/PT)
- Magnetic Particle Inspection (MPI/MT)
- Radiography (X-Ray/RT)
- Nital etch / heat damage inspection
- Leak and pressure testing
This ensures welded parts remain in one facility from start to finish—reducing handling risk, eliminating extra logistics time, and speeding up certification.
In many cases, yes—but proper evaluation is required.
MIL routinely welds components that are:
- Heat-treated
- Machined to final tolerances
- Anodized, plated, or coated
Before welding, our team reviews:
- Alloy behavior under heat
- Required post-weld treatments
- Whether finish or dimensional features may be affected
When necessary, we recommend masking, local shielding, or post-weld finishing to preserve or restore final properties.
Yes. MIL provides fully traceable documentation packages, which can include:
- Weld Procedure Specification (WPS)
- Procedure Qualification Records (PQR)
- Welder Qualification Records (WQR)
- Material certs and filler wire certs
- CWI inspection documentation
- NDT results when applicable
- Traveler and process documentation
These packages meet the requirements of aerospace primes, medical OEMs, and other regulated industries.
