6. What is it about the FCA welding electrode that provides alloys to the weld? A. slag B. shielding gas C. flux D. welding power supply

## Step 1<br />The Flux-Cored Arc Welding (FCAW) process uses a tubular electrode that contains a flux. This flux is a crucial component in the welding process.<br />## Step 2<br />The flux in the electrode melts during the welding process. This melting action creates a shielding gas that protects the weld from atmospheric contamination.<br />## Step 3<br />The flux also melts to form a slag, which floats to the surface of the weld. This slag acts as a protective layer, shielding the weld from the surrounding atmosphere.<br />## Step 4<br />The flux in the electrode also provides alloying elements to the weld. These alloying elements are essential for the formation of the weld metal.<br />## Step 5<br />The flux in the electrode is responsible for providing the alloying elements to the weld, which is why option C is the correct answer.
