Low-alloy Steel Electrode AWS E7015-G GB E5015-G
Introduction: J507NiTiB is a kind of high toughness low-alloy steel electrode
with low-hydrogen natrium type coating. The deposited metal
contains Ni-Ti-B. It has excellent low temperature impact toughness
and welding performance. DCRP (Direct Current Reversed Polarity).
Uses: Used for welding ships, boilers, mine construction machinery,
ocean engineering structures and other key structures.

1.The electrodes must be baked under about 400°C for an hour before
welding, and used as soon as baking is completed.
2.The stains on the weldments, such as rust, oil stains, moisture,
etc., must be cleared away before welding.
3.When welding, short arc must be used and stringer bead is
