Question: What is the primary function of the flux in a self-shielded flux-cored wire (FCAW-S)?
Answer options:
- To increase travel speed only ✅ To provide a shielding gas, deoxidizers, and slag formers
- To cool the weld puddle rapidly
- To add alloying elements only
Correct answer: To provide a shielding gas, deoxidizers, and slag formers
Explanation: The flux core in an FCAW-S electrode contains various ingredients that, when burned by the arc, produce a shielding gas to protect the weld pool from the atmosphere, as well as deoxidizers and slag-forming agents.
