Gas Metal Arc Welding (GMAW) / MIG Welding
A semi-automatic or automatic process that uses a continuously fed wire electrode and a shielding gas (like argon or CO₂).
🔹 Fast and easy to learn; ideal for production environments.
Gas Tungsten Arc Welding (GTAW) / TIG Welding
Uses a non-consumable tungsten electrode and an inert gas (usually argon) to shield the arc. Filler metal may be added manually.
🔹 High-quality welds; great for thin materials and precision work.
Flux-Cored Arc Welding (FCAW)
Similar to MIG welding, but uses a tubular wire filled with flux. It can be used with or without shielding gas.
🔹 Good for outdoor welding and thicker materials.
Shielded Metal Arc Welding (SMAW) / Stick Welding
A manual arc welding process that uses a consumable electrode coated in flux. The electric arc is struck between the electrode and the workpiece. The flux coating creates a gas shield and slag to protect the weld.
🔹 Common in construction and repair work.
