Abstract:

With the development of material technologies, the third-generation developed high-voltage sacks called AHSS (Advanced-High Strength Steel) are often used in automotive manufacturing for safety purposes. The combination of these sacks used in the shape, door supplement hair and direct manufacturing is usually done with the electric resistance point source. The electric resistance source plays an important place in the automotive industry because it allows for automation and large-scale production using robots. Another important point is the source parameters that affect the source quality during the source combination. These parameters for the electrical resistance point source are the source flow, the source time and the source chest pressure forces. In this study, 1200M and DP800HF AHSS sacks were studied the values optimized by the Taguchi method of the power flow, the power time and the impact of the power pressure forces on the firmness of the point core (source cutting). The Taguchi method used the L18 ortagonal series in the optimization application. With this series, the signal/bullying (S/N) ratio has been determining in the control of optimization results. When the results of the experimental studies and optimization process were studied, the hardness results obtained from the analysis by real application and Taguchi optimization were found close to each other.
