What is difference between tig and mig welding?

TIG (Tungsten Inert Gas) welding and MIG (Metal Inert Gas) welding are two common types of arc welding, but they differ in technique, application, and equipment. ### TIG Welding (GTAW)- Full Form: Gas Tungsten Arc Welding - Electrode: Non-consumable tungsten electrode - Shielding Gas: Typically argon or helium - Applications: High-precision work, thin metals, aerospace, stainless steel, and aluminum - Pros: - Produces clean, high-quality welds - Works well on thin materials - Precise control of heat and weld bead - Cons: - Slower process - Requires more skill ### MIG Welding (GMAW)- Full Form: Gas Metal Arc Welding - Electrode: Consumable wire electrode - Shielding Gas: Argon, CO₂, or a mixture - Applications: Fabrication, automotive, construction, heavy metals - Pros: - Faster than TIG - Easier for beginners - Suitable for thicker metals - Cons: - Weld appearance less clean than TIG - Less control over fine details ### Key Differences| Feature | TIG | MIG ||---------|-----|-----|| Electrode | Non-consumable tungsten | Consumable wire || Precision | High | Moderate || Speed | Slower | Faster || Best For | Thin metals, precise welds | Thick metals, industrial work |In short: TIG is for precision and quality, MIG is for speed and ease. Choice depends on the project’s material thickness and desired finish.
