Argonkesytyssuojakaasut, often shortened to argon shielding gas, refers to the use of argon gas in various industrial processes to prevent unwanted reactions with the surrounding atmosphere. Primarily, it is employed in welding and metal fabrication to create an inert environment around the molten weld pool. This inert atmosphere displaces oxygen and nitrogen, which can otherwise oxidize or embrittle the weld metal, leading to weaker and porous joints. By protecting the weld from these atmospheric contaminants, argon shielding gas ensures the integrity and quality of the finished product.

Beyond welding, argon is also utilized in metal casting and heat treatment. In casting, it can be used to purge molds before molten metal is poured, preventing oxidation of the metal surface and improving the casting's surface finish. In heat treatment, argon atmospheres can protect sensitive metals from decarburization or other atmospheric degradation during high-temperature processes. Its density, relative inertness, and availability make it a practical choice for many applications where a protective gas blanket is required. The effectiveness of argon as a shielding gas is dependent on factors such as flow rate and the specific application being performed.
