The four primary types of welding processes are:

Shielded Metal Arc Welding (SMAW) – "Stick Welding"

Uses a consumable electrode coated in flux.

Common in construction, repair, and fieldwork due to its simplicity and portability.

Gas Metal Arc Welding (GMAW) – "MIG Welding"

Uses a continuous wire electrode and shielding gas (e.g., argon or CO₂).

Ideal for automotive, manufacturing, and thin metals due to its speed and ease of use.

Gas Tungsten Arc Welding (GTAW) – "TIG Welding"

Uses a non-consumable tungsten electrode and shielding gas (often argon).

Provides high-quality, precise welds for stainless steel, aluminum, and exotic metals.

Flux-Cored Arc Welding (FCAW)

Similar to MIG but uses a tubular wire filled with flux (can be self-shielded or gas-shielded).

Common in heavy fabrication, shipbuilding, and structural steelwork.

Other notable processes include Submerged Arc Welding (SAW) and Oxy-Acetylene Welding, but the four above are the most widely used in industry. Let me know if you'd like details on any specific type!
