Abstract
The present invention relates to a coated welding electrode containing at least 0.5% of Cr based on the total weight of the welding electrode and comprising a metal core and a coating flux composition. In this welding electrode, the content of Na and K components in the coating flux calculated as (Na.sub.2 O + K.sub.2 O) is reduced below 1% based on the total weight of the coating flux composition, whereby amounts of fumes generated at the welding step, especially the amount of toxic soluble Cr, are suppressed and minimized.
