摘要：Shaped Metal Deposition (SMD) is a novel technology to build near-net shaped parts by successive weld deposition. The SMD rig consists of a robot with a Tungsten Inert Gas (TIG) welding torch and a manipulator, which are housed inside a sealed chamber. The heat transfer problem is modeled in a series of walls made by SMD of Ti-6Al-4V alloy. The studied specimens have different dimensions and were obtained using a wide range of process parameters (number of layers, layer height, wire feed rate, travel speed, heat input, etc.). The aim is to correlate the temperature field predicted using the finite element model developed by Centro Internacional de Métodos Computacionales en Ingeniería (Santa Fe, Argentina) to macro-, meso- and micrographical observations done at the Department of Metallurgy and Materials Engineering (Katholieke Universiteit Leuven, Belgium), as a way of validating the model of such a complex process.
