摘要：
The aim of this study is to develop the novel temperature measurement method during welding by using two high-speed cameras and the two-color thermometry method. This new method has some features, i.e. in-situ observation, high response speed, 2D measurement, wide temperature range and noncontact measurement. By using this method, the accurate in-situ temperature 2D distribution and history could be obtained during laser welding based on the selection of suitable band-pass filters for laser welding.
