Mac Trode E61118-G
AWS E11018-G
Descriptions & Applications:
Superior low hydrogen electrode, Ni Cr Mo type AWS E11018-G. These electrodes must not be used if the electrodes have become damp before being re-dried (moisture will cause weld metal cracking)*. Smooth arc low spatter easy strike and restrike. When requirements are specified for high strength steels in specific sub zero toughness such as in the North Sea offshore and submarine fabrication work the electrode offers excellent properties. Materials to be welded RQT 701 HY 100 Navy Q2N OS690 cast steel.
