E7015-G

W107Ni AWS A5.5 E7015-G  is a kind of low temdperature steel electrode containing Ni with low-hydrogen natrium type coating. DCRP (Direct Current Reversed Polarity). All-position welding.
Due to about 3.5% Ni in the weld, the weld metal has excellent tempering stability.
Application: Used for welding 3.5Ni low temperature low-alloy steel structures under -100℃.

Notes on Usages:
1. The electrodes must be baked under about 350℃ for an hour before welding and used as
soon as baking is completed.
2．When welding, middle and little criteria had better be adopted, as well as multi-layer and
multi-pass welding, and the layer temperature should be controlled below 200℃.
