Frequently Asked Questions

Q: Which AWS grade should I choose for carbon steel welding?

Depending on your requirements, we offer AWS A5.17 EL12, EM12, and EM12K. The choice depends on the base metal tensile strength and specific mechanical property requirements of your project.

Q: How should the sintering flux be prepared before use?

Sintering flux should be baked for 1-2 hours at a temperature of 300-350℃ to remove moisture and ensure a stable arc.

Q: What are the ideal storage conditions for submerged welding wire?

Store indoors at temperatures above 5°C with relative humidity not exceeding 60%. Maintain a distance of at least 300mm from walls and floors.

Q: Can this wire be used for large-diameter oil and gas pipes?

Yes, it is specifically designed for longitudinal and circular seams in large-diameter oil, gas, and water pipes, as well as pressure vessels.

Q: How does energy input affect the weld quality?

Welding input energy directly impacts the mechanical properties of the weld metal. We recommend a process evaluation to formulate exact specifications for your specific conditions.

Q: What base metal grades are compatible with this welding wire?

It is highly compatible with base metals of tensile strength grades Q235, Q345, and Q355.
