FAQS on welding rod 7018 specifications

Q: What are the key specifications of the E7018 welding rod?

A: The E7018 welding rod is a low-hydrogen, iron powder electrode with a tensile strength of 70,000 psi. It operates on AC or DC current and is designed for welding carbon steel, low-alloy, or high-strength steel. Its slag system allows smooth weld profiles and easy slag removal.

Q: How does the E7018 welding rod differ from E71T-11 welding wire?

A: The E7018 is a shielded metal arc (stick) electrode, while E71T-11 is a flux-cored gasless welding wire. E71T-11 offers higher deposition rates and is suited for outdoor use, whereas E7018 excels in structural applications requiring low-hydrogen properties.

Q: What current types are recommended for E7018 welding rods?

A: E7018 rods work with both AC and DC power sources. For DC, reverse polarity (electrode positive) is typically preferred. Ensure proper amperage settings (e.g., 90-150A for 3.2mm rods) based on rod diameter and material thickness.

Q: What are the storage requirements for E7018 electrodes?

A: E7018 electrodes must be stored in a dry, sealed container at 250-300°F (120-150°C) to prevent moisture absorption. Re-dry at 500-800°F (260-425°C) if exposed to humidity. Improper storage can lead hydrogen-induced cracking.

Q: Can E71T-11 welding wire be used for vertical welding?

A: Yes, E71T-11 wire supports all-position welding, including vertical and overhead, when using proper techniques. Its self-shielding flux eliminates external gas, making it ideal for windy outdoor conditions. Ensure settings align with AWS A5.20 specifications.
