In order to resolve the problem about the backward method of charge and low energy efficiency of explosives, the explosives with structure of honeycomb were prepared to ensure the quality of charge, and applied to double side explosion cladding to clad two combination plates. Results show that this technology significantly reduce the critical thickness of stable detonation of explosives, increases the energy efficiency of explosives, and saves the amount of explosives. Emulsion explosives with the thickness of 5 mm can stably detonate. The feasibility experiment of double side explosion cladding for steel of 45^# with thickness of 2 mm and steel of Q235 with thickness of 16 mm was carried out. Compared with the existing explosive cladding method, the consumption of explosives reduces by 83% in the case of cladding the same number of combination plates. The explosive cladding windows and collision speed of flyer plate are calculated before experiment. Upper and lower limits for collision velocity of flyer plate is 192 m·s^-1 < υ_p < 983 m·s^-1, and collision velocity of flyer plate for two groups which are 1089 m·s^-1 and 863 m·s^-1, respectively. It has shown that the calculation prefigures exactly the explosion cladding for steel of 45^#/steel of Q235.
