Gas humidification refers to the addition of water vapor to a gas flow to create a specific relative humidity (RH). Relative humidity is the ratio of partial pressure of water vapor (pH2O) in the gas to the equilibrium vapor pressure at saturation at a specific temperature. Gas humidification is frequently employed to humidify gases that do

Gas metal arc welding (GMAW) is a joining process that consumes shielding gas in significant volumes. Even hobbyists and other small-scale users of MIG welders require a robust gas delivery system to facilitate their welding process and protect the joint from reacting with atmospheric gases. Contamination of weld joints by ambient gases such as nitrogen
