Choosing between 7014 welding rod vs 7018 depends on required weld strength, hydrogen control, and application conditions. Based on manufacturer specifications and AWS classifications, both electrodes are low-hydrogen-related mild steel rods, but they are designed for very different priorities. Selecting the wrong option can affect penetration, crack resistance, and long-term weld reliability.
This guide explains the key differences between 7014 and 7018 welding rods, where each is best used, and how to choose the correct electrode based on application needs rather than convenience.

📋 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 7014 Welding Rod Used For?
According to manufacturer specifications, 7014 welding rods are iron powder, rutile-coated electrodes designed to increase deposition rate and ease of use. The added iron powder allows more weld metal to be deposited at lower operator effort, making 7014 suitable for faster production on mild steel.
7014 rods are commonly used for flat and horizontal welding, light structural work, fabrication projects, and maintenance repairs where productivity and smooth bead appearance are priorities. Aggregated user feedback often highlights easy arc starts and stable puddle control.
🔍 What Is a 7018 Welding Rod Used For?
Based on manufacturer data and AWS documentation, 7018 welding rods are low-hydrogen electrodes designed for high-quality structural welds. They emphasize ductility, toughness, and crack resistance, particularly in thicker or higher-strength steels.
7018 rods are frequently specified for code-regulated work, structural steel, pressure-related applications, and projects where hydrogen-induced cracking must be minimized. AWS guidance stresses the importance of dry storage for maintaining low hydrogen levels.
🔍 Key Differences Between 7014 and 7018 Welding Rods
The primary differences between 7014 and 7018 welding rods relate to hydrogen control, deposition rate, and application requirements, not basic tensile strength alone.
7014 welding rods prioritize ease of use and faster weld deposition. They are forgiving, produce smooth beads, and are commonly used in production or repair environments where speed and appearance matter more than hydrogen control.
7018 welding rods prioritize weld integrity and crack resistance. Their low-hydrogen coating reduces the risk of hydrogen-related cracking, making them better suited for structural and critical applications, even though they require stricter storage conditions.
🔍 When to Choose 7014 vs 7018 Welding Rod
Industry standards recommend selecting electrodes based on service requirements rather than convenience.
Choose 7014 welding rod when working on mild steel in flat or horizontal positions, when faster deposition is desired, and when hydrogen control is not critical.
Choose 7018 welding rod when welding structural steel, working under code requirements, or when crack resistance and ductility are essential.
Users commonly report that 7014 is favored for productivity-focused work, while 7018 is chosen when weld performance and long-term reliability take priority.
📌 Key Takeaways
- 7014 welding rods emphasize ease of use and higher deposition rates.
