Manufacturing Process of Gr5 Titanium Welded Tube

Forming Roll Ti‑6Al‑4V titanium strip or sheet into tubular profiles.

Welding Adopt TIG/GTAW welding or laser welding. Perform welding on both inner and outer sides under the shielding of 99.999% high-purity argon to avoid oxidation.

Finishing Treatment Carry out post-processing including annealing, surface polishing, pickling and anodizing as required.

Inspection & Testing Conduct 100% ultrasonic testing (UT). Additional mechanical and hydraulic tests are implemented, including flattening test, flaring test and hydrostatic pressure test.

FAQ About Gr5 Titanium Welded Tube

01.What NDT is required for Gr5 welded tube?

Ultrasonic Testing (UT): 100% of weld seam & body
Hydrostatic Testing: 1.5× design pressure, no leakage
Visual Inspection: Surface finish, discoloration, weld profile
Dye Penetrant (PT): For surface cracks in critical applications

02.Can Gr5 welded tubes be customized?

Yes. Custom options:

OD/Wall thickness (12.7–426 mm OD)
Length (cut to 1–20 ft)
Surface finish (pickled, polished, blasted)
Heat treatment (annealed, solution‑treated)
End fittings (flanged, threaded, plain)

03.How to store & handle Gr5 welded tubes?

Storage: Dry, clean area; avoid contact with steel/copper (prevent contamination)
Handling: Nitrile gloves; non‑metallic slings; avoid scratching (use protective caps)
Cleaning: MEK or isopropyl alcohol; no steel wool/abrasives

04.Why choose Gr5 welded tube over seamless?

Cost: Lower than seamless for large OD/thin wall
Availability: Faster lead times for standard sizes
Weld Integrity: Properly welded seams match base metal strength (solution‑annealed)
Size Flexibility: Larger OD (up to 426 mm) vs. seamless limits
