Frequently Asked Questions

Q: What is the primary difference between E7016 and E7018 electrodes?

Both are low-hydrogen electrodes, but E7016 is specifically optimized for high-tensile steel with excellent X-ray soundness and high deposition rates, making it ideal for petrochemical and nuclear plants.

Q: Can E7016 be used for all-position welding?

Yes, our E7016 electrodes support all welding positions, including PA, PB, PC, PD, PE, and PF, providing maximum versatility for structural steel projects.

Q: What base metals are most suitable for E7016 welding rods?

They are ideally suited for structural steel, steel castings, thin plates, steel strips, and carbon steel tubes, especially those requiring high mechanical strength.

Q: Does this electrode support both AC and DC welding?

Yes, the E7016 welding rods are compatible with both AC (Alternating Current) and DC (Direct Current) power sources.

Q: Do you offer customized packaging for bulk orders?

Absolutely. We support full OEM and ODM services, allowing you to design your own packaging for your brand's specific market needs.

Q: How do you ensure the stable quality of the welding electrodes?
