Product Name: Professional Manufacturer Iron Powder Low Hydrogen Potassium Type Welding Electrodes/Raw Material E7018 Model NO.: E7018 Welding Power: AC/DC Function: Low Hydrogen Type Electrode, Gravity Electrode, Moisture-Proof Electrode, Vertical-Down Slag Characteristic: Acidic Electrode Coating Type: Low Hydrogen Potassium Welding Core Type: Carbon Structural Steel Length: 200-300mm Diameter: 2.5mm Material: Carbon Steel Type: E (Carbon Steel Electrodes/ Low Alloy Steel Electrodes) Trademark: HAIQIAO Transport Package: Carton Specification: 2.0mm, 2.5mm, 3.2mm Origin: Wenzhou HS Code: 8311100000 Product Description Carbon Steel Welding Electrodes AWS E7018(GB E5018)Description: E7018(J506Fe) is an iron powder low hydrogen potassium electrode.It is used on both AC and DC in all position. As the coating contains iron powder, it that highly efficient welding and can reduce welding layers.Application: It is suitable for welding carbon structure and low alloy steel structure, such as 16Mn, etc.ChemicalCompositionDepositedmetal(%)CMnSiSP≤0.12≤1.6≤0.75≤0.035≤0.040MechanicalPropertiesofDepositedmetalTestItemTensileStrengthós(Mpa)YieldStrengthós(Mpa)Elongationδ5(%)ImpactValue(J)-30°CGuranteed≥490≥400≥22≥27Tested520-580≥41024-3050-180Hydrogen diffuse of weld metal: ≤0.8ml/100g (glyceric method)X-ray Radiographic Inspection: 1 GradeSizes&RecommendedCurrent(ACorDC)Weldingroddiameter(mm)2.53.24.05.0weldingcurrent(A)90-120120-150170-200210-250NOTES: 1. Electrodes must be baked for 1 hour at 350°C before welding operation.2. It is essential to clean up rusty,oil scale,water and impurities on welding parts.3. Short arc operation is required when welding. Narrow weldingtrack is proper.4. Electrode is as positive pole when oprarion on DC.
