1. Effect of Welding Heat Input on the Microstructure and Mechanical Properties of Dissimilar Friction Stir-Welded Copper/Brass Lap Joint
Dissimilar lap welded joints of copper and brass metals were fabricated by friction stir welding (FSW) method at various welding heat inputs. The effect of welding heat inputs on the microstructure and mechanical properties of overlap welded joints at at two different join configurations (i.e. Advancing side and Retreating side joint configurations) was inve

2. Simulação do Processo de Soldagem Elétrica por Centelhamento de um Aço para Trilhos Ferroviários. Parte 1: Análise de Tensões Residuais Via Elementos Finitos
Resumo Trilhos longos, soldados pelo processo Flash Butt Welding (FBW), são a realidade das ferrovias brasileiras de média e alta carga por eixo. Embora apresentem características desejáveis do ponto de vista do comportamento dinâmico da via, as soldas são regiões de descontinuidade estrutural e mecânica onde se originam tensões residuais, e que est

3. Influence of the electrical current, upset force and tempering heat treatment in the flash butt welding of bimetal band saw blades / Influência da corrente elétrica, da força de recalque e do tratamento térmico de revenimento na soldagem topo-a-topo por centelhamento de serras de fita bimetálica.
The performance of bimetal band saw blades depends mainly on the features of joining their ends, carried out by flash butt welding process. This is a resistance welding method, which consists of electrical heating followed by a fast material forging. The present work has the objective of studying the influence of changing the electrical current, upset force

4. Recent developments in high productivity pipeline welding
Installation of new pipelines is predicted to grow at a rapid rate over the next twenty years, due in part to the increase use worldwide of combined cycle power generation plant using natural gas a fuel. The need to construct large diameter pipelines over long distances has led to an increased demand to improve the productivity of pipeline girth welding. Man

5. CORROSÃO EM ELOS DE AMARRAS OFFSHORE: UM ESTUDO DE CASO / CORROSION IN OFFSHORE MOORING CHAINS: A CASE STUDY
O objetivo principal desta pesquisa foi caracterizar o fenômeno de corrosão localizada na região da junta soldada de elos de amarras do tipo ORQ utilizados em sistemas de ancoragem offshore. Para tal, foram selecionados elos de amarras retirados de serviço ao final de sua vida útil programada e sem sinais de corrosão localizada (elos sem corrosão) e e

6. INFLUÊNCIA DA FRAÇÃO DE MARTENSITA REVENIDA NA VIDA EM FADIGA DE UM AÇO ESTRUTURAL COM APLICAÇÕES EM SISTEMAS DE ANCORAGEM / INFLUENCE OF TEMPERED MARTENSITE ON THE FATIGUE LIFE OF STRUCTURAL STEEL FOR MOORING SYSTEMS
The great explor atory potential in deep waters has led companies in the oil sector to search for the necessary technological improvement to make the offshore exploration and production feasible. In parallel to searching for new technologies, the reduction in risks of structural failure has become the sector`s constant practice, considering that such failure
