Frequently Asked Questions

Q: Why is it necessary to store E7018 welding rods in a drying oven?

E7018 electrodes are low-hydrogen types and are highly prone to absorbing moisture from the air. To maintain their chemical properties and prevent hydrogen-induced cracking, they must be stored in a specialized drying oven.

Q: How should I re-bake E7018 electrodes if they have been exposed to air?

Electrodes exposed to atmospheric moisture should be re-baked at temperatures between 350-400°C for 1 to 2 hours to restore the performance of the coating.

Q: Can E7018 be used for mild steel without baking?

While mild steel can be welded with unbaked E7018 electrodes, it is not recommended for critical work as the weld strength may not reach the required high specifications.

Q: What does the "70" and "18" in E7018 signify?

The "70" refers to the minimum tensile strength of the weld metal (70 ksi), while "18" indicates the welding position (all-position), the coating type (low hydrogen), and the compatible welding currents (AC or DC).

Q: How does the iron powder coating benefit the welding process?

The addition of iron powder increases the deposition efficiency, allowing more metal to be deposited per hour, while also stabilizing the arc and reducing spatter.

Q: What precautions should be taken when replacing E7018 with other electrodes?

If you must replace E7018 with a different specification, you must adjust the welding process parameters (current, voltage, speed) according to the material's specific conditions to ensure quality is controllable.
