| Introduction: E7015 is a kind of carbon steel electrode with low-hydrogen natrium type coating specially used for vertical downward fillet weld. DCRP (Direct Current Reversed Polarity). Mainly vertical downward welding. It has excellent welding performance. In top-down vertical downward welding, the arc is stable, the slags do not fall off and it has good slag detachability, regular ripples and beautiful appearance of weld. | |||||||||||||||||||||
| Uses: Suitable for welding vertical downward fillet weld of carbon steel and low-alloy steel structures. | |||||||||||||||||||||
| Chemical Composition of Deposited Metal (%)
| |||||||||||||||||||||
| Mechanical Properties of Deposited Metal
| |||||||||||||||||||||
| Diffusible Hydrogen Content in Deposited Metal:≤8.0ml/100g(Glycerine Hydrogen Test) | |||||||||||||||||||||
| X-ray Radiographic Inspection:ⅠDegree | |||||||||||||||||||||
| Reference Current(DC+)
| |||||||||||||||||||||
| Instructions: 1.The electrodes must be baked under 350℃ 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, directly downwards, generally with no weaving or just a little weaving. | |||||||||||||||||||||
