Certified Welding Inspector (CWI) — Sample · easy

In Shielded Metal Arc Welding (SMAW), what provides the shielding for the molten weld pool?

A Gases produced by the burning electrode flux coating

B A water-cooled nozzle

C An external inert gas cylinder

D Granular flux poured ahead of the arc

Explanation. In SMAW the flux coating on the covered electrode decomposes in the arc, generating shielding gas and forming slag that protect the weld. External gas is used in GMAW/GTAW, and granular flux is the SAW process.
