Oxygen Transmitters and analyzers are often used as a diagnostic tool to ensure the quality of the inert atmosphere within a glove box. Unlike a storage compartment within a car’s dashboard, however, there is another type of glove box used by industry, government institutions, and university laboratories. This “other” type of glove box (A.K.A. dry […]

Measuring Oxygen for Welding Applications
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) […]
Atmosperic Conditions Affect Weld Quality
Many fabricators experience welding problems at different times of the year. Moisture (H20) is a prime source of hydrogen. At arc temperatures, water breaks down releasing hydrogen atoms that cause porosity in weldments. Shielding gas supplies are controlled to very low moisture content (-70°F dewpoint or lower). Likewise, the atmospheric conditions in a fabricating facility […]
