英文摘要
Residual stress is important factor of destruction behavior and weld distortion. For control of residual stress, highly accurate evaluation about welding phenomena is necessary. Here, we paid attention to molten pool convection which relates to temperature distribution during welding process. Real-time observation of molten pool during laser welding process was carried out using an intense X-ray beam from synchrotron radiation facility(Super Photon ring-8 GeV : SPring-8). We succeeded the simultaneous monitoring of molten pool shapes and convection phenomena in molten pool during laser welding process.
