Abstract: To find out the reasons for the delamination, broken edge and folds of the Ti plate, the bonding strength of the explosive welding Ti-steel clad plate is tested, and the surface quality of the Ti plate is analyzed. The results shows that the metallurgical defect of Ti ingot, broken edge and heterogeneous oxidation layer contribute to the weak bonding of the clad plates. Then, the suitable measures for the quality control and surface treatment of the Ti plate are put forward.
