What does 'cast' refer to in welding terminology?

• A. Diameter of a single loop of wire
• B. Coating thickness
• C. Diameter of electrode
• D. Filler metal type

Answer: (A)

In welding terminology, cast refers to the size of the filler metal loop that forms as wire feeds and melts in the weld. When people talk about cast in this context, they are describing the diameter of a single loop of wire—the loop’s size is used to characterize how much filler metal is being fed and deposited per pass. This makes cast a measure tied to the physical loop of wire, rather than the material’s coating, the electrode’s overall diameter, or the filler metal’s chemical type. So, the diameter of a single loop of wire is the aspect of cast that’s being referenced, because it directly relates to how the wire is laid down in the weld. The other options describe different attributes: coating thickness belongs to electrode coatings, the electrode diameter is a separate dimension of the metal rod, and filler metal type is about the chemical composition of the weld filler.
