GRICON 75

WELDERS FRIENDLY HEAVY COATED BASIC TYPE, HYDROGEN-CONTROLLED ELECTRODE.

IDENTIFICATION
GRICON 75, E 7015

CLASSIFICATION
AWS A 5.1 E7015

DESCRIPTION
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. The welds are of radiographic quality.
