Gas Introduction
Argon is a colorless, odorless monatomic gas with a density 1.4 times that of air and 10 times that of helium. Argon is an inert gas that does not react chemically with other substances at room temperature and is insoluble in liquid metals at high temperatures. It demonstrates its superiority when welding non-ferrous metals. It can be used for bulb inflation and arc welding of stainless steel, magnesium, aluminum, etc., also known as “argon arc welding”.
