In arc welded double side T-joint, different procedures were explored in order to understand the influence in the residual stress the second pass does not increase the maximum residual stress, however it increases the area with tensile residual stress. These models are based on finite elements therefore, a mesh sensitivity analysis was performed in order to evaluate the minimum element size required for accurate results. For this purpose, the commercial software ESI SYSWELD was adopted, since it is one of the most advanced tools for this purpose. In this communication, T-joint welded configurations are investigated, considering arc welding and laser beam welding processes. Considering these changes and the materials properties at the different temperature values, it is possible to obtain reliable models of the welding processes.

The most advanced tools take into account the thermo-metallurgical and thermo-mechanical changes that take place during the welding processes. Science and Technology of Materials welcomes contributions in the form of original research papers, review articles and technical notes reporting advances on those fields, emphasizing new materials, new products and devices, and new technologies.įormerly known as Ciência & Tecnologia dos Materiais See moreĪdvances in computational tools for welding process simulation have been noteworthy, allowing to assess complex phenomena, as is the case of welding distortion and residual stress.

The scope of the journal covers a wide range of topics in materials science that are of interest to the SPM, encompassing electrochemistry, corrosion and protection of materials, extractive metallurgy and recycling, electronic and optoelectronic materials, biomaterials, forest materials, polymeric and composite materials, foundry, heat treatment and surface engineering, tribology, and fracture. Science and Technology of Materials is the official journal of SPM, the Portuguese Society of Materials (Sociedade Portuguesa de Materiais), providing a forum for publishing peer-reviewed papers related to both fundamentals of materials science and technological application of engineering materials.
