In order to resolve the current issue about the backward method of charge and low energy efficiency of explosives, a kind of explosive with the structure of honeycomb is used to ensure the quality of the charge and is applied in double sided explosive cladding in which two plates can be combined in one explosion. A double sided explosive caldding experiment of stainless steel plates with the thickness of 3 mm and Q235 steel plates with thickness of 16 mm is carried out by using the explosive with the thickness of 7 mm. The explosive cladding window of the collision velocity is calculated as well as the collision velocity in two groups of the tests. The critical thichness of the explosive is remarkbly reduced with the explosive astricted by the honeycomb structure and the plates. The emulsion explosive with the thickness of 5 mm detonates stably. The result shows that, compared to the existing explosive cladding method, the consumption of explosives by using this method is reduced by 77% in the case of cladding the same number of combination plates. The calculation prefigure explosive cladding of stainless steel/Q235 steel exactly.
