Corrosion resistant multi-layered clad plates or sheets with high bonding strength is disclosed. According to the present invention, clad metals with high corrosion resistance such as Ti, Nb, V, or Zr and their alloys can be bonded with a cheap substrate such as Fe, Cu, or Ni and their alloys by the resistance seam welding. Using the insert metal causing the eutectic reaction, the clad metal can be strongly bonded with the substrate. Especially, corrosion resistant clad plates with excellent bonding strength can be fabricated by controlling the thickness and the microstructures of the eutectic reaction layer at the interface between the clad metal and the substrate or between the clad metal and the insert metal.
