Preparation method of tungsten copper-copper explosive welding composite board

The invention relates to a preparation method of a tungsten copper-copper explosive welding composite board, which comprises the steps of board pretreatment, board placement, explosive structure construction, explosive welding, post-treatment and the like, so that the bonding rate of the tungsten copper-copper board during explosion is improved, the bonding quality is remarkably improved, and the problems of board cracking and breaking in the explosive cladding process are reduced. According to the tungsten copper-copper explosive welding composite board finished product, tungsten copper-copper composite board layers are firmly combined, and the combination rate is larger than or equal to 99%; the shear strength can reach 200 MPa or above and far exceeds the requirement of the NB/T47002.3-2019 standard for the shear strength (larger than or equal to 140 MPa), and the method can be widely applied to special material processing or large-area composite board industrialization. 本发明涉及一种钨铜-铜的爆炸焊接复合板的制备方法，通过板材预处理、板材
