Related Application Notes

  • Not all welding applications require inert shielding gas. However when it does, use of an accurate and reliable trace oxygen analyzer is an essential tool.  TIG (Tungsten Inert Gas) welding of titanium requires the use of inert shielding gas, typically either high purity argon or a mix of argon/helium containing under 100 parts per million (PPM) of oxygen. Air contains 209,000 PPM of oxygen, so in order to create an acceptable atmosphere within the weld box (avoiding leakage of air into the box), a constant purge of inert shielding gas is normally applied.
