| Slide # | Topic | Rating | Comment | | :--- | :--- | :--- | :--- | | 3 | History of FCAW | ⭐⭐ | Too much text. Reduce to timeline (1950s – development, 1960s – commercial use). | | 7 | Shielding Gases | ⭐⭐⭐⭐ | Good info (CO2 vs. 75/25 Ar/CO2). Add a column for "Cost per CFH." | | 12 | Common Defects | ⭐⭐ | Photos are low resolution. Replace with high-contrast macro images of slag inclusion and porosity. | | 15 | Advantages vs. GMAW | ⭐⭐⭐⭐⭐ | This is the best slide. Clear, comparative, and useful for decision-making. |
: Unlike solid MIG wire, FCAW wire is hollow and packed with fluxing agents that stabilize the arc, add alloying elements, and protect the weld pool. Two Main Variants Self-Shielded (FCAW-S) flux cored arc welding ppt work
📌 Power source (DC – electrode positive typically), wire feeder, welding gun, ground clamp, shielding gas cylinder (if applicable). | Slide # | Topic | Rating |
