Advanced Tube Welding & Assembly Capabilities

From precision TIG welds in aerospace-grade materials to rapid MIG production runs, our certified welders deliver clean, strong assemblies with documented quality and full traceability.

TIG & MIG Welding

Both gas tungsten arc (TIG) and gas metal arc (MIG) processes for diverse materials. TIG preferred for critical aerospace/marine; MIG for production speed.

Fixture-Controlled Geometry

Custom welding fixtures maintain exact tube alignment, centerline positioning, and gap control throughout the weld cycle for repeatable dimensional accuracy.

Full Weld Traceability & Documentation

Every weld documented with heat input, travel speed, and shielding gas parameters. Visual inspection, penetrant testing, and load testing available.

Welding Design & Manufacturing Process

Engineering Analysis & DFM

Successful welded assemblies begin with careful joint design. Our engineers evaluate your assembly geometry to optimize for weld strength, appearance, and dimensional stability.

We recommend welding sequence, fixture design, and heat management strategies to minimize distortion and ensure consistent quality across production runs.

  • Tube material, diameter, and wall thickness specifications
  • Joint configuration: butt welds, socket welds, lap joints, or T-joints
  • Assembly alignment and dimensional tolerances
  • Weld process preference: TIG for quality, MIG for speed
  • Load and pressure requirements (for weld design verification)
  • Surface finish: as-welded or secondary cleaning/grinding
  • Quantity and delivery timeline

Frequently Asked Questions

What is the difference between TIG and MIG welding?
TIG (tungsten inert gas) produces cleaner, higher-quality welds—preferred for aerospace/marine. MIG produces faster welds—better for production volume. We recommend TIG for critical applications, MIG for standard production.
What materials can be welded?
Steel, stainless steel, aluminum alloys, copper, and titanium. Different shielding gases and electrode materials used for each. Material selection affects welding process and cost.
What are typical weld assembly tolerances?
Fixture-controlled assembly tolerances typically ±0.5–1.0 mm for critical dimensions. Tighter tolerances achievable for simpler geometries; confirm during design review.
Can you weld very thin-wall or thick-wall tubing?
Yes. Thin-wall (0.3 mm) requires precision TIG with lower heat input. Thick-wall (10+ mm) may require multi-pass welding and controlled cooling to avoid distortion.
Do you provide weld testing and documentation?
Yes. All production includes 100% visual inspection and dimensional verification. Load testing, penetrant testing (PT), and radiography available upon request. Full WPS/PQR documentation provided.
What is the typical lead time for welded assemblies?
Samples typically 10–14 business days from approval (includes fixture setup and first-piece inspection). Production runs may be expedited. Complex geometries may require 14–21 days.
