The processing area is reduced by double vertical explosive welding and rolling. Those micro defects are avoided such as " fusion" and " jet pile" in the bonding zone of large Ti plate of explosive welding. So the quality and welding ratio of interface are improved. To solve the technical problem of narrow weldability window of Ti,a minimum critical detonation velocity explosive was invented to enlarge the window after double vertical explosive welding experiment and optimization. A comprehensive protective structure made up of rigid protective plates and flexible protective walls was designed to restrict the movement of cladding plates in double vertical explosive welding effectively and protect the cladding plates from damage. The interface microstructure showed that the bonding interfaces were periodically micro and small wavy and there are no micro defects such as melt metal and swirl.
