From Consumable Metallurgy to Advanced Application Parameters
Slide 3: The Two Main Types (Critical Comparison)
Use a table for clarity.
| Feature | Gas-Shielded FCAW (FCAW-G) | Self-Shielded FCAW (FCAW-S) | | :--- | :--- | :--- | | Shielding | Requires external CO2 or Ar/CO2 mix | Flux core generates its own gas | | Wind Tolerance | Poor (needs screens/shelter) | Excellent (great for outdoor use) | | Slag Removal | Easier, often self-peeling | Tougher, requires chipping | | Penetration | Deep | Moderate | | Best Use | Heavy shop fabrication (structural steel) | Field erection, bridges, pipelines |

Slide 1: Introduction
Title: What is Flux Cored Arc Welding?
- Definition: Flux Cored Arc Welding (FCAW) is a semi-automatic or automatic arc welding process.
- The Mechanism: It uses a continuous tubular electrode (wire) filled with flux.
- The Heat Source: An electric arc is struck between the wire electrode and the workpiece, melting both.
- Key Distinction: Unlike Solid Wire (MIG/GMAW), the wire is hollow and filled with flux materials that shield the weld pool.
