Comprehensive Explanation of Helium Used in High-Precision Welding
Helium is a colorless, odorless, non-flammable gas that exists in the atmosphere at a concentration of about 5.2 parts per million. It is chemically inert and does not react with other elements or compounds under normal conditions. In theory, helium can be extracted from the air, but due to its extremely low concentration, industrial helium […]
