Types of Welding Explained: MIG vs TIG vs Stick vs Flux Core
1. MIG Welding (GMAW)
Also called gas metal arc welding. A continuous solid wire feeds through the torch, with shielding gas blocking air contamination.
✅ Pros: Easy to learn, fast, clean smooth welds, works on steel, stainless steel and aluminum.
✅ Best for: DIY builds, automotive parts, thin-to-medium metal mass production.
2. TIG Welding (GTAW)
Tungsten inert gas welding uses a non-melting tungsten electrode for ultra-precise heat control. You add filler wire separately by hand.
✅ Pros: Highest quality, spatter-free welds, perfect for thin sheets, aluminum and critical aerospace jobs.
⚠️ Cons: Steeper learning curve, slower speed.
3. Stick Welding (SMAW)
Shielded metal arc welding relies on coated stick electrodes; the flux coating creates its own protective shield when burned.
✅ Pros: No gas tank needed, ultra-portable, handles rusty/dirty thick steel, great for outdoor field work.
⚠️ Cons: Lots of slag to chip off, frequent electrode changes.
4. Flux-Cored Welding (FCAW)
Similar setup to MIG, but uses hollow wire filled with flux. Self-shielded versions skip shielding gas entirely.
✅ Pros: High penetration, wind-resistant, ideal for heavy structural steel, farm repair and outdoor construction.
⚠️ Cons: Heavy slag, rougher weld finish than MIG.
