Figure 3 shows the relationship between the shear strength of the wheel and the sum of the maximum voltage between the electrodes.There is a perfect correspondence between the shear strength of the wheel and the sum of the maximum voltage between the electrodes, and this relationship will have a certain relationship once the type of wheel and the energization time are determined depending on the shape and plate thickness, and as shown in Figure 3, in the case of 20 impulses, if the sum of the maximum values exceeds 10V, the shear strength of the wheel will increase. It can be seen that the quality of over 30 tons is guaranteed.
