The invention relates to a Z-pinch metal wire array load structure and a metal wire early-stage melting corrosion phenomenon analysis method. The load structure comprises an anode, a cathode and a metal wire array. The anode is arranged opposite to the cathode; and the metal wire array is arranged between the anode and the cathode. The metal wire array comprises at least two metal wires, wherein the metal wires are arranged in parallel. The Z-pinch metal wire array load structure also comprises Rogowski coils for measuring the metal wires respectively. The metal wires are arranged in the centers of the corresponding Rogowski coils respectively. One surface, directly facing the cathode, of the anode is provided with Rogowski coil installation grooves, and the Rogowski coils are arranged in the Rogowski coil installation grooves respectively. By measuring early-stage current of each metal wire in the wire array Z-pinch process, the physical phenomenon of early-stage melting corrosion evolution of each metal wire is explained; and monitoring of the early-stage current of each metal wire can help people to know the influence of factors of materials and electrode structures and the like on early evolution as well as influence of molten corrosion plasmas on current distribution.
