Different Types of Welding Gases And Their Use

Shielding gases fall into two categories—inert or semi-inert. Only two of the noble gases, helium and argon, are cost effective enough to be used in welding. These inert gases are used in gas tungsten arc welding, and also in gas metal arc welding for the welding of non-ferrous metals. Semi-inert shielding gases, or active shield gases, include carbon dioxide, oxygen, nitrogen, and hydrogen. These active gases are used with GMAW on ferrous metals. Most of these gases, in la… http://www.plasmatechnik.com/english/schweissbrenner/schweissbrenner.htm hubener recyclingSplet06. nov. 2007 · My original train of thought was that because both act more like a dense liquid than a gas, mabey they would work for say welding titanium or other reactive alloys that usuly require a purge box or trailing gas setup.

"SpletThe arc and the weld zone are shielded by a gas flowing through an outer nozzle. The shielding gas consists of argon, helium or gas mixtures of argon with either hydrogen or helium. A normal tungsten arc has a temperature of approximately 11 000°C but the constricted arc of a plasma torch can reach 20 000°C. " - Trailing gas in welding
