1. a kind of method for oozing micro boron element to weld metal, it is characterised in that include:

  • Boride is added in welding material, boride is 0.1-2 with the mass ratio of welding material:

    100;

    The welding material is electrode coating, or for the medicine core of flux-cored wire;

    When being welded using the above-mentioned welding material containing boride, boride goes out pure boron in welding arc spatial decomposition, and pure boron penetrates into weld metal, and welding current is more than 171A.
