| Abstract: | The technology on metal rapid prototyping based on gas-tungsten arc weding(GTAW) was introduced,including the advantages of this method and the experimental system composition.By analyzing the GTAW's processing,some welding parameters correlative with metal part processing were obtained.The relationship between physical dimension of seam and important parameters,which include welding current,welding speed and wire feed speed,was established by experiment and mathematics model.The welding parameters were optimized according to the requirements of metal rapid prototyping,then some metal parts were successfully deposited.The results show that the shape of metal parts is good and the surface of the metal parts is smooth,the technological parameters can meet the requirement of the metal rapid prototyping process. |
