| W807 | According with GB E5515-G | ||||||||||||||
| Introduction: W807 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 -80℃. | |||||||||||||||
| Uses: Used for welding 1.5Ni steel structures under -80℃. | |||||||||||||||
| Chemical Composition of Deposited Metal (%)
| |||||||||||||||
| Mechanical Properties of Deposited Metal
| |||||||||||||||
| Diffusible Hydrogen Content in Deposited Metal:≤6.0ml/100g(Glycerine Hydrogen Test) | |||||||||||||||
| X-ray Radiographic Inspection:ⅠDegree | |||||||||||||||
| Reference Current(DC+)
| |||||||||||||||
| Instructions: 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℃. 3.The stains on the weldments, such as rust, oil stains, moisture, etc., must be cleared away before welding | |||||||||||||||
