Types of Welding

1. Arc Welding (Electric Welding)

Uses an electric arc to melt and join metals.

Types include:

SMAW (Shielded Metal Arc Welding / Stick Welding)

GMAW (Gas Metal Arc Welding / MIG Welding)

GTAW (Gas Tungsten Arc Welding / TIG Welding)

FCAW (Flux-Cored Arc Welding)

SAW (Submerged Arc Welding)

2. Gas Welding

Uses a gas flame (commonly oxy-acetylene) to melt and join metals.

Example: Oxy-Acetylene Welding (OAW)

3. Resistance Welding

Heat is generated by electrical resistance.

Types include:

Spot Welding

Seam Welding

Projection Welding

4. Energy Beam Welding

Uses high-energy beams to weld with precision.

Types:

Laser Beam Welding (LBW)

Electron Beam Welding (EBW)

—

5. Solid-State Welding

No melting of base metal; joints form under pressure/heat.

Types:

Friction Welding

Ultrasonic Welding

Explosion Welding

Diffusion Welding

√Most common in workshops and industries:

Arc welding (SMAW, MIG, TIG)

Gas welding (Oxy-acetylene)

Spot welding (sheet metal work)
