An ideal fluid model of symmetrical colliding was taken to analyze the physical deformation on streamlines in explosive welding, and a theoretical formula of the angle deformation was deduced. The language of Visual C++ was adopted to make a program to calculate the angle deformation numerically. The size of the angle deformation is obtained as well as the change law of it. The result shows that, near the stagnation point, the angle deformation is always increasing along the coming fluid to the outing fluid, and the changing rate near the stagnation point is maximum. Along the outing fluid the angle deformation increases with the augment of the velocity at given impact angle, and decreases with the increasing of the impact angle at the given velocity. The contrast and verification of the calculated results are in agreement with the theory and the experiment of others' indirectly. Based on it, the influence on the formation of the wavy interface in explosive welding by the strain rate field near the stagnation point was discussed.
