The reconstruction of the geometry weld-deposited materials plays an important role in control torch path GMAW. This technique, which is classified as a direct energy deposition technology, experiencing new emergence due to its use welding and additive manufacturing. Usually, determined by computerised fabrication tools, but these software tools do not consider geometrical changes along case du...

Ultra-high-strength steel (UHSS) is a complex and sophisticated material that allows the development of products with reduced weight but increased strength can assist, for example, in automotive industry, saving fuel vehicles decreasing greenhouse gas emissions. Welding UHSS has certain complexity, mainly due to higher alloys heat treatments involved, which result microstructure sensitivity wel...

O objetivo deste trabalho é analisar a soldabilidade do aço DOMEX 700MPa, com utilização consumível ER70S-6 através processo GMAW, utilizados na fabricação de chassis caminhões e reboques. A análise foi realizada dos ensaios mecânicos feitos por corpos prova em laboratório, meio tração, dobramento microdureza. Nos resultados analisados, verificou-se que resistência mecânica microdureza metal ad...

Large portions of infrastructure buildings, for example highway- and railway bridges, are steel constructions reach the end their service life, as a reason an increase traffic volume. As lifetime extension commonly used weld detail (transverse stiffener) these structures, validated approach repair was proposed in this study. For this, welded joints made S355J2+N S960QL steels were subjected to ...

The beneficial effect of the friction stir processing (FSP) technique for improving properties fabricated additive parts through microstructural refinement and repairing metallurgical defects has shown its ability to be integrated into a hybrid manufacturing system. In present work, conventional GMAW TIG-based processes were further post-processed with process (FSP). case + processed beads, imp...
