What's features of TOKO brand Welding Flux SJ101,SJ301,SJ501?

 

The TOKO brand welding fluxes SJ101, SJ301, and SJ501 each have distinct features that make them suitable for different welding applications. Below is a summary of their key features:

TOKO SJ101 Welding Flux

  • Type and Composition: SJ101 is a fluorinated alkaline sintered welding flux with an alkalinity of 1.7 to 1.8, depending on sources. It has a neutral nature and does not significantly contribute silicon (Si) or manganese (Mn) to the weld metal.
  • Appearance and Granularity: It is a grayish-white circular granule with a particle size of 10-60 mesh (approximately 2.0-0.28mm).
  • Electrical Compatibility: It can be used with both AC and DC welding, with the weld wire connected to the positive pole during DC welding.
  • Welding Performance: SJ101 offers stable arc burning, easy slag removal, and aesthetically pleasing weld bead formation. The welds exhibit excellent low-temperature impact toughness.
  • Applications: Suitable for multi-pass welding and can be paired with carbon steel, low-alloy steel, austenitic stainless steel, and martensitic stainless steel welding wires. Commonly used for important welding products such as ship hulls, boilers, pressure vessels, and pipelines.
  • Pre-Use Preparation: Requires baking at 300-350°C for 2 hours before use, and the weldment should be cleaned of rust, oil, moisture, and other impurities.

TOKO SJ301 Welding Flux

  • Type and Composition: SJ301 is a silicon-calcium neutral sintered welding flux with an alkalinity of 1.0.
  • Appearance and Granularity: It appears as gray circular granules with a particle size of 10-60 mesh (approximately 2.0-0.28mm).
  • Electrical Compatibility: Suitable for both AC and DC welding, with the weld wire connected to the positive pole during DC welding.
  • Welding Performance: Known for its stable arc burning, easy slag removal, and aesthetically pleasing weld bead formation. The weld metal experiences a significant increase in silicon content and can also have a transition of manganese from the flux to the weld.
  • Applications: Primarily used for welding Q235 grade carbon steel and grades A, B, X42, and X46 pipeline steel. Also suitable for pressure vessels such as petroleum gas storage tanks and liquefied petroleum gas cylinders.
  • Pre-Use Preparation: Requires baking at 350°C for 2 hours before use.

TOKO SJ501 Welding Flux

  • Type and Composition: SJ501 is an aluminum-titanium sintered welding flux with an alkalinity ranging from 0.5 to 0.8.
  • Appearance and Granularity: It is a dark brown spherical granule with a particle size of 10-60 mesh (approximately 2.0-0.28mm).
  • Electrical Compatibility: Can be used with both AC and DC welding, with the weld wire connected to the positive pole during DC welding.
  • Welding Performance: Offers a transition of silicon and manganese to the weld metal, making it particularly suitable for high-speed welding processes such as twin-wire and multi-wire welding. Known for its good slag detachability, often used for fillet welding.
  • Applications: Ideal for welding alloyed structural steels, particularly those requiring high weld metal toughness.
  • Pre-Use Preparation: Not specifically mentioned, but generally, welding fluxes require proper storage conditions and cleaning of the weldment before use.

In summary, each TOKO welding flux offers unique characteristics tailored to specific welding requirements, from neutral to silicon-calcium and aluminum-titanium compositions, suitable for a wide range of materials and applications.
