| Abstract: | Experiments of explosive welding of titanium/steel clad plate were carried out by the method of high and low explosive detonation velocity and piecewise dynamite arrangement.On this basis,the microstructure features and mechanical properties of the bonding interface of 29 m2 Gr.2/Gr.70 tubesheet for condensers of power station were analyzed.The results show that there are no noise waves in the large area titanium/steel clad produced by the method of high and low explosive detonation velocity from 2250~2300 m/s and piecewise dynamite arrangement during the nondestructive examination(NDE),the interface is uniform.Moreover,the mechanical properties fulfill the standard ASTM B 898—2020 and satisfy the operational requirements of condensers. |
