  • Welding activated flux for structural alloy steels
    Patent number: 9511454
    Abstract: A welding activated flux for structural alloy steels including 40-50 wt % of SiO2, 25-30 wt % of MoO3, 5-10 wt % of TiO2 and 10-20 wt % of Cr2O3 is disclosed. Accordingly, with the use of the welding activated flux, the depth of the weld is significantly increased, thereby enhancing the mechanical strength of the weldment and reducing the distortion of the weldment.
    Type: Grant
    Filed: December 16, 2014
    Date of Patent: December 6, 2016
    Assignee: NATIONAL PINGTUNG UNIVERSITY OF SCIENCE & TECHNOLOGY
    Inventors: Kuang-Hung Tseng, Nai-Shien Wang
