抄録

The aim of this study was to develop a temperature measurement technique during welding using a developed multi-sensor camera based on a two-color thermometry method. This technique has specific features, such as in-situ temperature measurement, high response speed, two-dimensional (2D) noncontact measurement, and flexibility. Accurate in-situ temperature 2D distribution and its history can be acquired based on the selection of a suitable combination of band-pass filters for laser welding and the welded material. In addition, a clear visible image can be captured with the 2D temperature distribution using the developed multi-sensor camera even when a high welding speed is employed.
