2.2.2. Boundary Conditions For the CSOP-8 ceramic package, the parameters used in the parallel seam welding process follow: welding current of 184 A, pulse width of 2 ms, pulse repetition time of 140 ms, welding speed of 1.6 mm/s, electrode pressure of 3 N, and counterclockwise rotation angle of the fixture at 210°.
Brass (CuZn37) test samples are used for the quantitative comparison of the welding techniques, as this metal can be processed by all three welding techniques. At the end of the presented work, the suitability of resistance spot, ultrasonic and laser beam welding for connecting battery cells is evaluated.
Throughout the entire welding process, it can be observed that the temperature of the lid is significantly higher than that of other components, with the central temperature typically falling within the range 180–220 °C. The lid is the main area of welding, and it is manually placed on the welding ring before welding.
Parallel seam welding (PSW) is the most commonly employed encapsulation technology to ensure hermetic sealing and to safeguard sensitive electronic components. However, the PSW process is complicated by the presence of multiphysical phenomena and nonlinear contact problems, making the analysis of the dynamics of the PSW process highly challenging.
The resistance during parallel seam welding mainly includes the electrode resistance , the lid resistance , the ring resistance , the electrode/lid contact resistance , and the lid/ring contact resistance .
Further increasing the welding energy leads to electrode sticking and significant expulsion of bulk material , , , . Fig. 6. Electrical contact resistance and ultimate tensile force as function of welding energy.
