Argon

Argon is colorless, odorless, tasteless and nontoxic. Argon (Ar) is a noble gas that comprises 0.93 % of the earth’s atmosphere. Argon provides an inert and clean environment free from nitrogen and oxygen for annealing and rolling metals and alloys. In the casting industry, argon is used to flush porosity from molten metals to eliminate defects in castings. In the metal fabrication industry, argon is used to create an optimized atmosphere during open arc welding. Argon is frequently blended with carbon dioxide (CO2), hydrogen (H2), Helium (He) or Oxygen (O2) to enhance the arc characteristics or to facilitate stable metal transfer in Gas Metal Arc Welding (GMAW or MIG).
