Flux Cored Arc Welding (FCAW) is a semi-automatic or automatic process that utilizes a continuously fed tubular electrode containing flux to produce strong, high-quality welds. Introduced in the 1950s as a high-productivity alternative to stick welding (SMAW), it is now widely used in heavy industry due to its high deposition rates and deep penetration. 1. Fundamental Principles
Practical Applications and Use Cases
- Structural steel erection and fabrication.
- Shipbuilding and offshore structures.
- Heavy equipment and machinery repair.
- Pipeline welding (often as root pass with FCAW-G).
- Field maintenance where portability and wind resistance are needed (FCAW-S).
Slide 11 — Testing & Quality Control
- Visual inspection (bead profile, fusion, porosity).
- Non-destructive testing: ultrasonic, radiography, magnetic particle, dye penetrant.
- Destructive tests: bend, tensile, macro-etch to verify penetration and soundness.
- Procedure Qualification Record (PQR) and Welder Performance Qualification (WPQ) per code (e.g., ASME, AWS).
Specific Examples from the PPT
- Good slide: “Advantages of FCAW” – lists high deposition rate, all-position capability.
- Needs revision: “Disadvantages” – mentions spatter but doesn’t explain cause (high current + improper voltage).
- Missing slide: Common defects in FCAW (slag inclusions, worm tracking) and how to prevent them.
