Gas Shielded Welding is a welding process that uses a shielding gas to protect the weld area from contamination. This method helps to create a strong and clean weld by preventing oxidation and other reactions with the surrounding air. Common gases used include argon and carbon dioxide, which provide different benefits depending on the materials being welded. This technique is often employed in MIG welding (Metal Inert Gas) and TIG welding (Tungsten Inert Gas). Both methods are popular in various industries due to their efficiency and ability to produce high-quality welds on metals like steel and aluminum.
