The TOKO brand Submerged Welding Wire H08MnA (EM12) exhibits several notable features, making it a suitable choice for various welding applications. Here are the key features of this welding wire:

  1. Material Composition:
    • The welding wire is a copper-surfaced submerged arc welding wire, with a specific chemical composition designed for optimal welding performance.
    • The deposited metal composition typically includes low carbon content (≤0.10%), silicon (≤0.07%), manganese (0.80-1.10%), sulfur (≤0.030%), phosphorus (≤0.030%), chromium (≤0.20%), nickel (≤0.30%), and copper, ensuring excellent mechanical properties.
  2. Applicability:
    • Suitable for welding carbon steel and low alloyed steel, such as 16Mn and 14MnNb steel structures, as well as for soft steel and 490Mpa grade high-strength steel.
    • Widely used in industries like shipbuilding, steel structures, pipelines, heavy machinery, boilers, chemical containers, bridges, crane machinery, metallurgical machinery manufacturing, ocean structures, and nuclear power equipment.
  3. Performance Characteristics:
    • Exhibits excellent mechanical properties, with good molding of the weld bead and easy removability of slag.
    • Provides stable arc combustion during welding, resulting in consistent and high-quality welds.
    • The welding wire can be used with both AC and DC power sources, with the wire connected to the positive electrode when using DC.
  4. Aesthetics and Efficiency:
    • Produces weld metal with a fine appearance, ensuring aesthetic quality.
    • High deposition efficiency, making it suitable for mechanical and automatic welding processes.
  5. Compatibility:
    • Can be used with suitable fluxes, such as the fluorine-alkaline type SJ101 with an approximate alkalinity of 1.8, for enhanced welding performance.
    • Can also be paired with other suitable fluxes, like the silicon-calcium neutral type SJ301, to meet different welding requirements.
  6. Pre-Welding Preparation:
    • Before welding, it is crucial to clean the weldment surface of oil stains and rust to ensure optimal welding results.
  7. Welding Parameters:
    • A wide range of welding parameters can be adjusted to suit different welding conditions, including welding current and voltage.

In summary, the TOKO brand Submerged Welding Wire H08MnA (EM12) offers a combination of excellent mechanical properties, stable arc combustion, ease of use, and versatility, making it a reliable choice for various welding applications across multiple industries.
