  • Welding manganese steel
    Patent number: 4104504
    Abstract: Sections of cast manganese steel, or manganese steel to be interfaced to another steel, are joined by electroslag welding. Metallurgical limitations, operating parameters and physical attributes of the guide tube are imposed to retard embrittlement of the base metal and weld metal as well, to prevent tearing, to assure satisfactory ductility, and to preserve the integrity of the austenitic manganese steel in the weld metal.
