AK-W607 Low-Temperature Steel Electrode for All-Position Welding.
A low-hydrogen sodium-coated electrode designed for welding low-temperature steels with excellent impact toughness down to -60℃.
Product Overview
AK-W607 is a low-temperature steel electrode with a low-hydrogen sodium coating containing nickel, suitable for all-position welding using direct current reverse polarity.
The deposited metal maintains good impact toughness at -60℃, making it suitable for critical low-temperature applications where mechanical performance under extreme conditions is essential.
It meets the EN ISO 2560-B:E 7015-G, AWS A5.5 E7015-G, and GB/T 5117 E5015-G classifications, ensuring compatibility with international welding standards.
Application: Welding -60C low temperature steel structure, such as 13MnSi63, 09MnNiNb, E36, etc.
Key Benefits
Excellent Impact Toughness at -60℃.
The deposited metal achieves a minimum impact value of 54 J at -40℃, with performance maintained at -60℃, ensuring reliability in cryogenic environments.
Low-Hydrogen Sodium Coating
The low-hydrogen sodium coating reduces the risk of hydrogen-induced cracking, especially in high-strength and low-temperature applications.
All-Position Welding Capability
AK-W607 can be used in flat, horizontal, vertical, and overhead positions, allowing consistent weld quality across complex joint geometries.
Nickel-Enhanced Toughness
The inclusion of 0.60-1.0% nickel in the deposited metal improves toughness and ductility, particularly in low-temperature service conditions.
Where It Is Used
- Welding low-temperature steel structures such as 13MnSi63, 09MnNiNb, and E36.
- Critical joints in cryogenic storage tanks and pipelines operating at sub-zero temperatures.
- Structural components exposed to extreme cold in Arctic or high-altitude environments.
Who It Is For
- Welding consumable distributors supplying low-temperature welding electrodes.
- Fabricators working with low-temperature steels in cold climates.
- Contractors involved in cryogenic or low-temperature infrastructure projects.
Problems It Solves
- Achieving reliable weld metal toughness at -60℃ in critical low-temperature applications.
- Reducing the risk of hydrogen cracking in high-strength low-temperature steels through low-hydrogen electrode selection.
- Using a single electrode for all welding positions without sacrificing mechanical properties or weld quality.

- Keep electrodes dry in sealed packaging; re-dry if exposed to moisture before use.
- Clean joint surfaces thoroughly to remove oil, rust, paint, and moisture before welding.
How It Compares
AK-W607 and E7015 both belong to the low-hydrogen sodium-coated electrode family and are suitable for all-position welding. AK-W607 is specifically formulated for low-temperature service with enhanced toughness down to -60℃, while standard E7015 electrodes may not guarantee the same impact performance at such low temperatures. Cellulosic electrodes offer deeper penetration but are not suitable for low-temperature applications due to higher hydrogen content and lower toughness.
