Is the ER70s-2 electrode the most common electrode used in sheld metal arc welding?

The ER70S-2 electrode is indeed one of the most commonly used electrodes in gas metal arc welding (GMAW) and is popular for its versatility and ability to weld a variety of steel types. It is particularly effective for welding carbon steels and is known for its good arc stability and weld quality. However, in shielded metal arc welding (SMAW), other electrodes like E7018 or E6013 are more commonly used, as they are specifically designed for that process. Thus, while ER70S-2 is prevalent in GMAW, it is not the most common electrode for SMAW.
