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