Shielding Gas Myths: What Really Affects TIG Weld Quality
Understanding the Role of Shielding Gas in TIG Welding
Shielding gas plays a critical role in TIG (Tungsten Inert Gas) welding by protecting the weld area from atmospheric contamination. This is vital because impurities can lead to porosity and compromise the integrity of the weld. Inert gases like argon and helium are commonly used due to their non-reactive nature, ensuring a stable arc and clean weld. Understanding the properties and functions of these gases helps in choosing the right one for various welding applications.
