32Refractory metals — are a class of metals that are extraordinarily resistant to heat and wear. Refractory metals are said to be poorly resistant to oxidation and corrosion. [UFL EMA 6625: Advanced Metal Processing, Summer 2008, Lecture 09] These properties make them …
33Shielding gas — Shielding gases are inert or semi inert gases that are commonly used in several welding processes, most notably gas metal arc welding and gas tungsten arc welding. Their purpose is to protect the weld area from atmospheric gases, such as oxygen,… …
34Inert gas — Inert gases is also used in a narrower sense for noble gases. An inert gas is any gas that is not reactive with elements.Like the noble gases an inert gas is not necessarily elemental and are often molecular gases. Like the noble gases the… …
