AWS/ASME SFA-5.1: E 7028–H8
DIN 1913 : E 51 54 B (R) 12 160
EN 499 : E 38 5 B 73 H10

Application/properties:

High-efficiency electrode having a weld metal recovery of approx 165%. preferably used for welding fillets. Weld metal is crack-free and very tough. Smooth and clean welds blending into base metal without undercut. Suitable for welding primer painted component. Slag is easily removable. Welds are of X-ray quality.
