Suojakaasussa

Suojakaasussa refers to the use of a shielding gas in welding and other industrial processes. A shielding gas is a substance that is inert or semi-inert that is used to protect the molten weld pool from atmospheric contamination. This contamination, primarily from oxygen and nitrogen in the air, can significantly weaken the weld and degrade its properties. Common shielding gases include argon, helium, carbon dioxide, and mixtures of these. The specific gas or gas mixture chosen depends on the type of metal being welded, the welding process being used, and the desired weld quality. For instance, argon is often used for aluminum and stainless steel, while a mixture of argon and carbon dioxide is common for carbon steel. The shielding gas is typically delivered to the weld area through the welding torch. Proper gas flow rate and coverage are crucial to ensure effective protection and achieve a sound weld. In addition to welding, shielding gases are also employed in processes like plasma cutting and additive manufacturing to maintain material integrity and achieve desired outcomes.
