What are our core advantages?
50% Faster Deposition:
The flux coating contains over 50% highly active iron powder, resulting in significantly faster deposition than conventional electrodes. This increases single-pass weld formation speed by 30%-50%, significantly shortening the welding cycle for large components.
High-Strength Connection Guarantee:
The weld metal boasts a tensile strength of 480MPa+ and a yield strength of 350MPa or higher. It's compatible with low-alloy steels like Q345 and meets the long-term load-bearing requirements of heavy-duty structures.
Full-Duty Adaptability:
Stable arc starting is achieved with both AC and DC reverse polarity, effectively reducing porosity in humidity levels ≤85%, and achieving high-quality welds even on lightly corroded workpieces.
Easy to Operate:
The arc is gentle and spatter-free, resulting in smooth weld transitions. Even beginners can quickly master flat and horizontal welding techniques, reducing subsequent grinding by 60%.

Operation Guide
1. Pretreatment Process
Welding Rod Drying: 150°C for 1 hour (200°C for 2 hours in a humid environment). After drying, store in an 80-100°C heat preservation container.
Workpiece Cleaning: Remove surface oil and thick rust. Maintain a 60°±5° angle for groove welding, with a gap of 2-4mm.
2. Parameter Settings
Current Matching: 3.2mm corresponds to 140-180A, 4.0mm corresponds to 180-240A, 5.0mm corresponds to 240-320A, and 6.0mm corresponds to 320-400A.
Speed Control: 8-15cm/min, adjusted according to weld pool fluidity. Layered welding is recommended for thick plates.
3. Special Working Conditions
Low Temperature Environment (<0°C): Preheat the workpiece to 80-120°C.
Thick Steel Plates (≥25mm): Use multi-pass welding, maintaining a temperature of 150-200°C between passes.
FAQ
Q: What are the main differences between the e7024 and e6010 welding rods?
A: The core differences between the two lie in the coating type and application scenarios: the e7024 is a high-efficiency iron powder type, focusing on high deposition efficiency in horizontal and horizontal welding, suitable for thick plate welding over large areas; the e6010 is a cellulose type, designed for all-position welding (especially vertical welding in a downward direction), making it more suitable for complex structures such as pipelines.
Q: Can the e7024 be used to weld stainless steel?
A: Not recommended. The e7024 is designed specifically for mild steel and low-alloy steel. Welding stainless steel will result in weld embrittlement due to the material mismatch. We recommend using a dedicated stainless steel welding rod (such as the E308 series).
Q: How should unused welding rods be stored after opening?
A: After opening, seal the rod immediately in a moisture-proof container and store it in a humidity environment of ≤60%. Use within 24 hours. If the rod exceeds this time, it must be re-dried at 150°C for 1 hour before use. After the second drying, it must be used within the same day.
