| Summary: | Turbulence Flow Casting Method (TFC) is a new welding method that combined casting and welding processes. This method has been successfully applied to repair surface defect at gray cast iron component and chromium steel casting. The result is a good quality joint with similar properties to the base metal. Experimental study of TFC method at ADC 12 will bc conducted ro approve the upplication of TFC method at aluminium alIoys component. The important point in TFC process is that the liquid metal flow must be turbulence. This experiment applied turbulence flow with Reynolds number 11150. Other parameters, which determine the success of joining process, are preheat temperature and thickness of liquid metal penetration. The parameters are calculated by mean of physical properties of aluminium at liquid condition. The other support parameters such as gating design and pouring time are according to parameters used in previous research. The result of this experiment shows similar of microstructure and hardness among fusion line zone, weld pool and base metal. This experiment approves that TFC method can be applied at cast aluminium alloy ADC 12, but the formula for determining the parameters can't be applied.
