AWS/SFA 5.1: E7018, IS 814: EB5426H3JX, DIN: 5144B1026
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. 115%. The welds are of radiographic quality.
