what are the two elements that comprise a welding electrode in smaw?
core wire
amperage
alloy elements
flux coating

Explanation:

In Shielded - Metal Arc Welding (SMAW), a welding electrode is composed of a core wire and a flux coating. The core wire provides the filler metal for the weld, and the flux coating protects the weld area from contamination and provides other beneficial functions during the welding process. Amperage is a parameter related to the welding current, not an element of the electrode. Alloy elements may be present in the core wire but are not one of the two main elements that define the structure of the electrode.

Answer:

core wire, flux coating
