What is TIG welding of frame assemblies?

TIG welding of frame assemblies capability for titanium components

Certified welding capability for TIG welding of frame assemblies, with full inert gas shielding, weld procedure qualification, and operator certification.

Engineering Parameters & Capabilities

Gas Tungsten Arc Welding (GTAW/TIG) for titanium uses a non-consumable tungsten electrode with argon shielding at the torch face, trailing shield, and backup purge. Titanium's reactivity above 600°C demands complete oxygen exclusion until the weld zone cools below 300°C, specifically for titanium components. Precision titanium components present unique challenges: balancing dimensional accuracy with cost per part. Process selection (mill vs. turn vs. EDM vs. laser) is optimized for each feature.

Parameter Specification
Heat Input Low — narrow HAZ (1–3 mm)
Shielding Argon face + trailing shield + backup purge
Weld Speed 100–300 mm/min (manual); 1000 mm/min (orbital)

Engineering Capabilities & Limits

Hole Types Supported

N/A

Heat Control Measures

Triple-shield argon protection: torch nozzle, trailing shield (10–20 L/min), and backup purge. Interpass temperature is monitored with an IR pyrometer; max 120°C between passes.

Flatness & Stress Relief

Welding fixture with copper backup bars for heat sinking. Sequenced stitch welding pattern to balance thermal stresses.

Tolerance

Weld distortion: +0.5 mm typical; +0.1 mm with fixture
