E 7018 Welding Electrode

E 7018 is a low hydrogen electrode; the electrode is used with metal that tends to crack and thick sections. The electrode produces weld with excellent toughness and high ductility and reduces the risk of hydrogen embrittlement cracking when welding thick sections.

E 7018 produces excellent quality welds with steel requiring strength of 70,000 PSI and above; the electrode can be used with medium carbon, high carbon, and low-alloy steel.

One of the important points to consider for E 7018 is the storage and drying procedure; the electrode must remain in a low humidity environment to minimize the moisture in the electrode coating to reduce hydrogen level and avoid hydrogen cracking.

E 7024 Welding Electrode

E 7024 welding rod deposits metal rapidly; therefore, the electrode is categorized as a fast-fill electrode. The electrode is used for high-speed welding on a flat or horizontal surface. E 7024 electrode arc penetration is shallow; the weld bead is slightly convex and smooth with heavy slag formation. The electrode contains an iron powder, which increases the welding deposition rate.
