Abstract: Metal transfer behavior of six kinds of self-shielded flux-cored
wire (SSFCW) is studied using the apparatus of SSFCW high-speed
photography self-made. Six kinds of metal transfer modes of
SSFCW were obtained through observation for high-speed
photograph film and analysis. It is believed that the research
is of magnificent for improving operative performance and
mechanical properties of SSFCW and dynamics characteristic of
welding power.
