Carbon Steel Welding Rod

I. Core Advantages

1. 50% Ultra-High Deposition Efficiency

The flux coating contains more than 50% highly active iron powder, so the deposition speed is much faster than that of traditional electrodes.

The formation speed of single-pass welds is increased by 30%-50%, which greatly shortens the welding cycle of large components (such as storage tanks and ship hulls).

2. High-Strength Connection Guarantee

The weld metal has a tensile strength of ≥480MPa and a yield strength of ≥350MPa.

Compatible with low-alloy steels such as Q345, it meets the long-term load-bearing requirements of heavy-duty structures (such as bridges and machine bases).

3. Full-Duty Adaptability

Power Compatibility: Supports AC (Alternating Current) and DC reverse polarity, ensuring stable arc starting.

Environmental Resistance: Can effectively reduce porosity under working conditions with humidity ≤85%.

Workpiece Adaptability: High-quality welding can still be achieved on slightly corroded workpieces, reducing pretreatment requirements.

4. Easy Operation and Low Loss

The arc is gentle and spatter-free, with smooth weld transition, allowing beginners to quickly master flat and horizontal welding techniques.

The subsequent grinding workload is reduced by 60%, lowering labor and consumable costs.

II. Chemical Composition of Deposited Metal (%)

Note: The contents of sulfur and phosphorus are far lower than the guaranteed values, which effectively avoids weld embrittlement and balances strength and toughness.

III. Typical Application Scenarios

IV. Operation Guide

1. Pretreatment Process

Welding Rod Drying: Dry at 150°C for 1 hour in a normal environment; dry at 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; for groove welding, maintain an angle of 60°±5° and a gap of 2-4mm.

2. Welding Parameter Settings

Layered welding is recommended for thick-plate welding to avoid stress concentration.

3. Special Working Conditions Handling

Low-Temperature Environment (<0°C): Preheat the workpiece to 80-120°C.

Thick Steel Plates (≥25mm): Adopt multi-pass welding, and maintain an interpass temperature of 150-200°C.

V. Frequently Asked Questions (FAQ)

Q1: What are the core differences between E7024 and E6010 welding rods?

A: The core differences lie in flux coating type and application scenarios:

E7024: High-efficiency iron powder type, focusing on high deposition efficiency in flat/horizontal welding, suitable for large-area thick-plate welding.

E6010: Cellulose type, supporting all-position welding (especially downward vertical welding), suitable for complex structures such as pipelines.

Q2: Can E7024 be used to weld stainless steel?

A: Not recommended. E7024 is specially designed for low-carbon steel/low-alloy steel. Welding stainless steel with it will cause weld embrittlement due to mismatched components. It is recommended to use dedicated stainless steel welding rods (such as E308 series).

Q3: How to store unused E7024 welding rods after opening?

A: ① Seal in a moisture-proof container, with storage humidity ≤60%; ② Use up within 24 hours; ③ If overdue, re-dry at 150°C for 1 hour. After the second drying, it must be used on the same day and cannot be dried repeatedly.
