E 8018–G–H4
AWS/ASME SFA-5.5:Application/properties :
is used for welding fine-grained steels used in pressure vessels, boilers, pipes and storage tanks. Its weld metal has high toughness and low hydrogen content. This electrode has a stable and concentrated arc and is therefore suitable for positional welding . Its weld is of good quality in terms of radiographic examination.
