This study looks at the characterization and performance of ultrasonic welding for ABS-PC (Mychril) polymer blends used in EV station applications. Experiments were conducted and a detailed characterization of the welded interfaces were performed using Scanning Electron Microscopy (SEM) to examine their structure. Fourier Transform Infrared Spectroscopy (FTIR) was deployed to identify chemical interactions and any potential degradation, and X-ray Diffraction (XRD) to evaluate changes in crystallinity caused by the welding process. SEM images showed consistent fusion and minimal voids, while FTIR and XRD tests showed that key functional groups remained intact with slight changes in crystallinity. Mechanical tests were also carried out on the welded samples that involved tensile, impact and fracture assessments. Pearson’s heat map coefficient analysis was performed to understand the influence of input process parameters on the mechanical strength outcomes. This research shows that ultrasonic welding is a suitable, sustainable, and effective method for assembling ABS-PC samples in EV applications, providing mechanical reliability and design flexibility.
