Laser welding is one of useful methods in manufacturing processes. However, in welding processes, porosi ties sometimes occur in weld metal. Therefore, it is demanded to establish the method to predict and sup press porosities to make sound joints. Numerical simulation has been developing and become one of availa ble techniques to make it realized. Even so it’s still very difficult to predict its formation with comp te accuracy. In this study, numerical analysis to simulate the behavior of bubbles moving i...
