Experimented Study on Lower Limit Dynamite Amount of Explosive Welding Weldability Window

It is discovered in explosive welding of T10/Q235 composite sheet that the practical least dynamite that needed for successful explosive welding has reduced 15~20% than ones assured by dynamical parameter of tradition weldability window.So the modifying formula of explosive welding dynamite is given.According to calculating dynamite of the formula,it has not only been cutting down the welding dynamite and minishing environmental harm of explosive effect,but the demand of welding quality needed in engineering use can be satisfied,through production examining of explosive welding for composite sheet of 3Cr13/Q235 and 1Cr18Ni9Ti/cast steel and hardness 62 brass/Q235.So the modifying formula is defined as "the best welding window of dynamite amount" that has important significance for guiding explosive welding production of composite sheet
