Also referred to as a low-hydrogen rod this electrode has a flux coating with a very low hydrogen content allowing a minimal amount of hydrogen into the weld puddleThe molten weld beads are protected from contamination moisture and hydrogen in the atmosphere by the iron-containing. 7018 downhill for pipe welding 7018 is similar to a fill freeze electrode running it downhand the molten slag tries to overrun the puddle.
