Does MIG and TIG Welding Use the Same Gas? Understanding the Key Differences

ByWelderology Team

When starting out in welding, one common question is whether MIG and TIG welding can use the same shielding gas. While both processes rely on gas to protect the weld pool, their gas requirements are distinct. Understanding the differences can significantly impact weld quality and efficiency. The Role of Shielding Gas in Welding Shielding gas…

What Gas Is Used for MIG Welding? Shielding Gases Explained

ByWelderology Team

Gas Metal Arc Welding (GMAW), better known as MIG welding, relies on shielding gas to protect the weld from contamination. Without it, atmospheric gases like oxygen and nitrogen would cause porosity, weak joints, and excessive spatter. However, not all shielding gases are created equal—different gases influence arc characteristics, weld appearance, penetration, and even the cost…
