Low Temperature Steel Electrode AWS  E****-C1 GB E****-C1
 

Introduction: W**7Ni is a kind of low temperature steel electrode containing Ni with low-hydrogen natrium type coating. DCRP (Direct Current Reversed Polarity). All-position welding. The weld metal still has excellent impact toughness under **0°C.

Uses: Used for welding low temperature steel structures under **0°C, such as *9Mn2V, *6MnVAl, 3.5Ni, etc.

Chemical Composition of Deposited Metal (%)

Mechanical Properties of Deposited Metal

Diffusible Hydrogen Content in Deposited Metal: ≤6.0ml/**0g(Glycerine Hydrogen Test)

X-ray Radiographic Inspection: Degree 1

Reference Current (DC+)

Instructions:
1.The electrodes must be baked under about **0°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 suitable.
