From the results of the welding pressure experiment in Figure 17 d, it can be seen that with the increase in welding pressure, the weldment contact is more compact, the energy conversion efficiency is improved, and the maximum pull-off force is obtained at 85 N; when the pressure exceeds 85 N, the welding quality shows a decreasing trend due to the intensification of the stress concentration phenomenon.
