Product Description Product DescriptionWelding rod Welding rod (covered electrode) is a coating (coating) that is evenly and centripetally pressed onto the metal welding core. The welding core is the metal core of the welding rod. In order to ensure the quality and performance of the weld, there are strict regulations on the content of each metal element in the welding core, especially the content of harmful impurities (such as sulfur, phosphorus, etc.), which should be strictly limited and better than the parent material. The welding rod consists of two parts: the welding core and the coating. Different types have different welding cores.AWSCMnSiSPCrNiMoVE7015≤0.15≤1.25≤0.75≤0.015≤0.025≤0.20≤0.30≤0.30≤0.08E7016≤0.15≤1.60≤0.75≤0.015≤0.025≤0.20≤0.30≤0.30≤0.08E7018≤0.15≤1.60≤0.75≤0.015≤0.025≤0.20≤0.30≤0.30≤0.08E7018-1≤0.15≤1.60≤0.75≤0.015≤0.025≤0.20≤0.30≤0.30≤0.08E7015-G≤0.12≤1.25≤0.50≤0.015≤0.020-2.0-2.75--E8015-G≤0.120.60-1.60≤0.90≤0.015≤0.025-0.30-1.00≤0.35≤0.05E8018-C3≤0.120.40-1.25≤0.80≤0.015≤0.020≤0.150.80-1.10≤0.35≤0.05E7015-G is a special welding rod for low alloy high strength steel, which has excellent low temperature toughness and welding performance. The following is its detailed introduction:Typical Chemical Composition C: ≤0.10% Mn: 0.5-1.5% Si: ≤0.6% Ni: 0.8-1.5% (key for low-temperature toughness) S/P: ≤0.025% (low impurities for crack resistance)Mechanical PropertiesTensile Strength (σb): ≥490 MPa Yield Strength (σs): ≥390 MPa Elongation (δ): ≥20% Impact Toughness (-70°C): ≥27J (Ni enhances cryogenic performance)Key FeaturesLow-Hydrogen Type: Requires baking (350°C ×1hr) to avoid cold cracking. DC Reverse Polarity (DCEP): Stable arc with moderate penetration. All-Position Welding: Suitable for complex structures. Cryogenic Toughness: Nickel (Ni) ensures high impact resistance at -70°C, ideal for LNG tanks, Arctic equipment, etc.Applications Cryogenic Pressure Vessels: e.g., LNG storage. Offshore Structures: Cold-resistant steel components. Bridges & Infrastructure: Low-temperature pipelines, mining machinery.Company ProfileEquipment and ProcessApplicationPackaging
