Last Updated: January 2026
Choosing between 6010 welding rod vs 7018 depends on joint conditions, power source, and required weld properties. Based on manufacturer specifications and AWS guidance, these two electrodes are designed for very different applications, even though both are commonly associated with stick welding. Selecting the wrong rod can affect penetration, weld soundness, and long-term durability.
This guide explains the technical differences between 6010 and 7018 welding rods, where each is commonly used, and how to choose the correct option based on application requirements rather than habit.

đź“‹ How We Evaluate Welding Rods
This research-based guide compares welding rods using manufacturer technical specifications, aggregated user feedback from verified purchasers, industry standards from the American Welding Society (AWS), and application-specific requirements for stick welding.
We do not personally test consumables. Evaluations are based on documented technical data, user-reported performance patterns, and alignment with industry standards. Readers should verify rod compatibility with their equipment and base materials. For critical applications, consult certified welding professionals.
🔍 What Is a 6010 Welding Rod Used For?
According to manufacturer specifications, 6010 welding rods are cellulose-coated electrodes designed for deep penetration and fast-freezing weld puddles. They are commonly used where joint conditions are less than ideal.
6010 rods are often selected for open-root welds, pipe welding, field repairs, and structural work involving dirty, rusty, or painted steel. AWS classification guidance notes that 6010 electrodes require DC+ (DCEP) power and are valued for their ability to dig through surface contamination.
Aggregated user feedback consistently highlights strong arc force and aggressive penetration as defining characteristics of 6010 rods.
🔍 What Is a 7018 Welding Rod Used For?
Based on manufacturer data, 7018 welding rods are low-hydrogen electrodes designed to produce strong, ductile welds with good mechanical properties. They are commonly used where weld quality and crack resistance are critical.
7018 rods are frequently specified for structural steel, pressure-related applications, and code-regulated work. AWS documentation indicates that low-hydrogen electrodes help reduce the risk of hydrogen-induced cracking, particularly in thicker or higher-strength steels.
Unlike 6010, 7018 rods typically require dry storage conditions to maintain low hydrogen levels.
🔍 Key Differences Between 6010 and 7018 Welding Rods
The main differences between 6010 and 7018 welding rods relate to penetration, coating type, and weld characteristics rather than strength alone.
6010 welding rods produce deep penetration with a fast-freezing slag system. They excel in open-root joints and poor surface conditions but result in rougher bead appearance and higher spatter.
7018 welding rods offer smoother bead profiles, lower hydrogen content, and improved mechanical properties. They are better suited for clean joints and controlled environments where crack resistance and weld integrity are priorities.
🔍 When to Choose 6010 vs 7018 Welding Rod
Industry standards recommend selecting electrodes based on joint design, cleanliness, and service requirements.
Choose 6010 welding rod when welding dirty or rusty steel, performing open-root passes, working outdoors, or needing maximum penetration.
Choose 7018 welding rod when welding clean structural steel, working on code-regulated projects, or when low hydrogen levels and ductility are required.
Users commonly report that switching between these rods within the same project is common, with 6010 used for root passes and 7018 used for fill and cap passes.

🟢 FAQs
Q: Can 7018 replace 6010 welding rod?
According to AWS guidance, 7018 cannot directly replace 6010 for open-root or contaminated joints due to differences in penetration and slag behavior. Consult qualified professionals for personalized advice.
Q: Is 6010 welding rod stronger than 7018?
Manufacturer classifications indicate that 7018 provides higher tensile strength and ductility, while 6010 prioritizes penetration. Consult qualified professionals for personalized advice.
Q: Why does 7018 require special storage?
AWS documentation explains that 7018 rods are low-hydrogen electrodes and must be kept dry to prevent moisture absorption. Consult qualified professionals for personalized advice.
âś… Conclusion
Based on manufacturer specifications, user feedback, and AWS standards, the difference between 6010 welding rod vs 7018 lies in application, not preference. 6010 is designed for aggressive penetration and challenging joint conditions, while 7018 is intended for clean, structural welds requiring low hydrogen levels and strong mechanical properties. Selecting the correct electrode improves weld quality, reliability, and long-term performance.
