Abstract

The heat transfer, fluid flow, and the solidified surface profile during GMA fillet welding was investigated using a three dimensional numerical model. A boundary fitted coordinate system was used to accurately calculate the temperature and velocity fields in the complex physical domain considering deformation of the weld pool surface. The additional heat from the metal droplets was also modeled considering the interaction between the droplets and the pool. By minimizing the total free surface energy, the free surface profile was calculated considering the additional filler metal.
