gázmixekben
Gázmixekben refers to combinations of gases used in various industrial and scientific processes, most notably in welding, cutting, and controlled atmosphere applications. A gas mix is created by blending two or more gases in precise ratios to achieve desired properties such as oxidation control, shielding effectiveness, flame temperature, or heat transfer. Common gases used in mixes include argon, helium, carbon dioxide, oxygen, nitrogen, and hydrogen. The proportions are typically expressed by volume percentage and are critical to the performance of the process.
In welding, a typical example is GTAW (TIG) where an argon–helium mix provides a stable, bright arc
For respiratory protection, breathing gas mixtures such as oxygen–helium or oxygen–nitrogen are used in saturation diving
Safety considerations for gas mixes include proper handling, leak detection, and correct storage, as some mixtures
