Gricon Lilac, E 6018
CLASSIFICATION
AWS A 5.1 E6018
DESCRIPTION
Welder’s friendly heavy coated basic type, hydrogen-controlled, iron powder electrode with high deposition efficiency. Weld able in all positions (F.H.V.O). Welding technique including arc striking/restricting calls for practical experience for best result. The bead appearance is smooth and the slag is compact, thick and easily detachable. Deposition efficiency of weld metal is approx.112%.The welds are of radiographic quality.
