AK-606NiCrCu Ultra-Low Hydrogen Electrode for Corrosion-Resistant Bridge Steel.
A sodium-type, low hydrogen electrode with high toughness for all-position welding of important bridge structures made from Q500-NH steel.
Product Overview
AK-606NiCrCu is a low hydrogen, sodium-coated covered electrode designed for all-position manual metal arc welding. It is formulated for use on critical bridge structures fabricated from corrosion-resistant steel Q500-NH.
The electrode uses direct current reverse polarity (DC reverse) and delivers good arc stability and weldability. The deposited weld metal exhibits high plasticity and toughness, meeting the requirements for demanding structural applications.
Application: For welding of important bridge corrosion-resistant steel Q500-NH.
Key Benefits
Ultra-Low Hydrogen Content
The sodium-type coating minimizes hydrogen in the weld metal, reducing the risk of hydrogen-induced cracking in high-strength, corrosion-resistant steels like Q500-NH.
High Toughness and Plasticity.
The weld metal maintains good ductility and impact resistance, which is essential for joints exposed to dynamic or low-temperature service conditions.
All-Position Welding Capability
The electrode performs reliably in flat, horizontal, vertical, and overhead positions, allowing one consumable to be used across multiple joint orientations.
Stable Arc with DC Reverse Connection.
The electrode operates with consistent arc performance when used with direct current reverse polarity, ensuring smooth welding and reduced spatter.
Where It Is Used
- Welding of important bridge structures made from corrosion-resistant steel Q500-NH.
- Critical joints in steel structures requiring high toughness and low hydrogen content.
- All-position welding in fabrication and field erection of heavy bridge components.
Who It Is For
- Welding consumable distributors supplying electrodes for bridge and infrastructure projects.
- Bridge fabricators working with Q500-NH steel and requiring low hydrogen electrodes.
- Field welding teams handling critical joints where weld metal toughness and crack resistance are essential.
Problems It Solves
- Welding Q500-NH steel with electrodes that do not meet low hydrogen and high toughness requirements, risking delayed cracking in service.
- Using multiple electrode types to cover different welding positions, increasing inventory and complexity.
- Lack of consistent weld metal properties due to variable hydrogen content in filler metal.

Use Guide
- Use direct current reverse polarity (DC reverse) for optimal arc stability and weld quality.
- Select electrode diameter based on joint thickness and position, then set current within the recommended range.
- Keep electrodes dry in sealed packaging; re-dry if exposed to moisture before use.
- Clean joint surfaces of rust, oil, paint, and moisture before welding to ensure sound weld metal.
How It Compares
AK-606NiCrCu and E6016-G both meet GB/T 5118-1995 and are used for low hydrogen welding. AK-606NiCrCu has a sodium-type coating with enhanced toughness and is suitable for all positions. E6016-G is also low hydrogen but may have different mechanical properties and is typically used in flat and horizontal positions only. For high-strength, corrosion-resistant steels like Q500-NH, the higher toughness and all-position capability of AK-606NiCrCu make it a better fit.
