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.
