Welding in Steel Fabrication: Choosing the Right Process

🔥 Welding in Steel Fabrication: Choosing the Right Process

1️⃣ SMAW (Stick Welding)

Best for: On-site repairs & fieldwork
Pros: Portable, versatile—works outdoors and in challenging conditions
Cons: Slower pace, frequent electrode changes

2️⃣ GMAW (MIG Welding)

Best for: Shop fabrication, thin-to-medium steel
Pros: Fast, clean, minimal slag
Cons: Requires shielding gas; less effective in windy environments

3️⃣ FCAW (Flux-Cored Arc Welding)

Best for: Heavy steel sections, outdoor jobs
Pros: High deposition rate; works with or without shielding gas
Cons: More spatter—extra cleanup needed

4️⃣ SAW (Submerged Arc Welding)

Best for: Long, straight seams like beams and plates
Pros: High speed and deep penetration
Cons: Only works in flat/horizontal positions

5️⃣ GTAW (TIG Welding)

Best for: Precision work, thin materials
Pros: Clean, high-quality welds
Cons: Slow and requires high skill levels

6️⃣ ESW/EGW (Electroslag/Electrogas Welding)

Best for: Thick vertical sections (columns, girders)
Pros: Capable of single-pass welds on thick materials
Cons: Specialized equipment; high heat
