We pride ourselves on the design capabilities we offer at TVC. In addition to providing unique solutions for the welding and inspection industries, we also customise our well-established equipment.
An aerospace industry client contacted us with a requirement to measure either oxygen or moisture at the welding torch to very low levels to ensure compliance with NADCAP standards. In accordance with the specification, oxygen content should not exceed 20ppm and moisture should not exceed 125ppm (-40°C dewpoint) at the torch head after gas bottle exchanges and/or bulk gas delivery.
For this application, we manufactured a specialist adapter that can be fitted onto any size Tig torch gas shroud. This provides a precise seal, easily used with any of our purge monitors, and enables quick, accurate measurements of Oxygen content at the torch head required by NADCAP specifications for manual and automated welding processes. Using dual sensor technology, our purge monitors can accurately measure the Oxygen content in shielding and purging gases.
We received another enquiry for almost exactly the same application from a client who specialises in the internal cladding of carbon steel pipes for the Energy, Oil, and Gas industries. Our innovation allowed us to immediately demonstrate a solution for a non-aerospace industry client producing Inconel Weld Clad Overlays. of CRA pipes.
If you have a requirement that requires the fast and accurate measurement of the Oxygen or Moisture content in Shielding or Purging gases, please contact us to discuss your requirements.
