We'll respond with DFM notes and pricing within 48 hours.
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
Welding Process Control
- Joint Preparation — Clean tube ends, align in custom fixture, set precise gaps for optimal weld penetration
- Weld Process Selection — TIG for quality/critical work; MIG for production speed. WPS (Welding Procedure Specification) established and followed
- Controlled Welding — Documented heat input, travel speed, and shielding gas ensure repeatable metallurgy and appearance
- Quality Inspection — 100% visual inspection, dimensional verification, load testing (when specified), full documentation provided
