SME PE99-126

In 3-D welding, a droplet of the melted electrode wire is detached to form a metallic deposit. By properly depositing the drops, the metallic parts are made layer by layer. In order to accurately control the resultant shape of the part, as well as its mechanical and metallurgical properties, the drop size and detachment timing must be precisely controlled. The proposed system for rapid prototyping based on 3-D welding addresses the challenge of simultaneous geometric regulation of dimensional tolerances and mechanical and metallurgical properties of the part, by combined heat and mass transfer control
