Titanium Welding and Fabrication in Chennai
Nobel Weld provides titanium welding and fabrication in Chennai for components and assemblies in titanium, zirconium, nickel alloys, duplex and special stainless steels. We cut, form, fit up, weld and finish-machine to your drawing.
Reactive metals are welded under trailing shields and argon purge with oxygen monitoring, to procedures qualified to ASME Section IX. Each assembly is tested and documented before despatch.
Fabrication scope
- Cutting, forming, rolling and fit-up of exotic-metal components
- Welded housings, nozzles, spools and assemblies
- Weld overlay and cladding on wear and sealing faces
- Post-weld finish machining to final tolerances

- GMAW and SMAW where the material permits
- WPS, PQR and WPQ qualified to ASME Section IX
Titanium weld colour: how we judge a titanium weld
Titanium picks up oxygen above about 400 °C. The colour of the finished weld shows how well it was shielded. Silver is fully protected; light straw is generally acceptable; dark straw, blue, violet and grey show contamination that weakens the joint. We control this with trailing shields, purge chambers and oxygen monitoring of the purge gas, and accept the weld colour against the customer specification.

FAQ
Fabrication and welding: common questions
Is your titanium welding and fabrication in Chennai qualified to a code?
Yes. Welding procedures and welders are qualified to ASME Section IX (WPS, PQR, WPQ), and pressure parts are built to ASME Section VIII Division 1 when required.
How do you prevent contamination when welding titanium?
With high-purity argon, trailing shields, back purge or argon chambers, oxygen monitoring of the purge gas, and clean, dedicated tools. The weld colour is checked against the acceptance criteria.
Which tests are done on fabricated assemblies?
Visual and dimensional inspection, dye penetrant testing, radiography or ultrasonic testing, and hydrostatic or pneumatic tests as the code and the customer require.
