## Description

- description: Herein, the temperature distribution during ultrasonic welding of carbon
    fiber–reinforced polypropylene (CF/PP) was investigated. The temperature distribution
    was assessed using a thermographic camera that specifically targeted the lateral
    aspect of the welded section of the adherend in the lap joint. In addition, single
    lap shear tests were performed on the resulting welded joints. The welding experiments
    confirmed that the amplitude of the sonotrode impacts both the temperature distribution
    during welding and the quality of the joint, eventually affecting the mode of
    failure. By applying the half-width method to the measured temperature distribution
    in the thickness direction of the adherend, we assessed the spread of the high-temperature
    region centered on the welding interface. In this study, at a small amplitude
    (36 μm), the half-width of the maximum temperature showed approximately twice
    higher slope than at other amplitudes, indicating a wider high-temperature range
    even at the same interface temperature.
