AKJ101Q Sintered Flux for Submerged Arc Welding of Low Carbon and Low Alloy Steels.
A fluorine-alkali type sintered flux with alkalinity ≥1.8, designed for stable arc and clean slag deposit when used with matching welding wires on low carbon and low alloy steel structures.
Product Overview
AKJ101Q is a fluorine-alkali type sintered flux with alkalinity ≥1.8 and particle size of 10~60 mesh (approximately 2.0 ~ 0.28 mm). It is suitable for both AC and DC power supplies, with the welding wire connected to the positive pole when using DC current.
The flux produces a stable arc, a well-shaped weld bead, and slag that deposits easily and detaches cleanly. The deposited metal exhibits good mechanical properties, including excellent low temperature impact toughness.
Application: Cooperate with corresponding welding wires (such as H08MnA, H10Mn2,JH-WQ1, JH-WGX2, etc.), mainly used for welding low carbon steel and some low alloy steels (such as 16Mn, x65, X70, 14MnNiq, WQ490D, WQ490E, etc.) structure and submerged arc welding of boiler pressure vessels, ships, bridges, oil pipelines, etc. Deposited metal has; good low temperature impact toughness.
Key Benefits
Stable Arc with DC Power.
When used with DC current and the welding wire connected to the positive pole, AKJ101Q maintains a stable arc, reducing spatter and improving weld consistency.
Clean Slag Deposit
The slag formed during welding deposits uniformly and lifts off easily, minimizing post-weld cleaning and reducing the risk of slag inclusion.
Good Low Temperature Impact Toughness.
The deposited metal achieves good low temperature impact toughness, making it suitable for applications requiring reliable performance in cold environments.
Compatibility with Multiple Wires.
AKJ101Q is recommended for use with welding wires such as H08MnA, H10Mn2, JH-WQ1, and JH-WGX2, enabling consistent performance across various base metals.
Where It Is Used
- Submerged arc welding of low carbon steel structures.
- Welding of low alloy steels including 16Mn, X65, X70, 14MnNiq, WQ490D, and WQ490E.
- Fabrication of boiler pressure vessels, ships, bridges, and oil pipelines.
- Applications requiring good low temperature impact toughness in the weld metal.
Who It Is For
- Welding consumable distributors supplying flux for structural and pressure vessel welding.
- Fabricators of steel structures, ships, and pipelines requiring consistent flux performance.
- Contractors working on boiler and pressure vessel projects needing reliable submerged arc welding consumables.
Problems It Solves
- Achieving consistent weld quality when using flux with variable slag behavior or poor detachment.
- Meeting low temperature impact toughness requirements in the deposited metal for critical applications.
- Matching flux chemistry to base metal composition without requiring multiple flux types for different steels.

Use Guide
- Select matching welding wire such as H08MnA, H10Mn2, JH-WQ1, or JH-WGX2 based on base metal and application requirements.
- Ensure the flux is stored in a dry, sealed container to prevent moisture absorption.
- Use DC current with the welding wire connected to the positive pole for optimal arc stability.
- Clean the joint surfaces of oil, rust, and moisture before welding to avoid porosity and defects.
- Remove slag completely between passes to prevent contamination in subsequent weld layers.
How It Compares
AKJ101Q is a fluorine-alkali sintered flux with alkalinity ≥1.8, suitable for low carbon and low alloy steels. It differs from basic fluxes in its higher alkalinity and sintered structure, which provide better slag control and arc stability. Unlike some acidic fluxes, it delivers better toughness in the deposited metal. It is not intended for use with high-strength or stainless steel wires without verification of compatibility.
