This work investigates the weldability of Inconel 718 using metal inert gas (MIG) welding process called ‘cold transfer’. arc is reported for working with a lower heat input compared to other processes. The consequences are less base impaired, low deformation and residual stress level in assembly. In order check these abilities, metallographic, texture, chemical analyses have been carried out. Results show that MIG cold transfer has good properties inasmuch as no defect detected stresses...
This article deals with temperature characterisation by infrared thermography during welding. To demonstrate the versatility of this technique, two welding processes were investigated different materials: cold metal transfer inert gas al alloy and resistance spot galvanised steel. Two experimental methods used to characterise without requiring implementation thermocouples. The validity these is demonstrated metallurgical characterisations. error on measured values assessed regarding initial...
Le soudage homogène (métal d'apport identique au métal de base) l'alliage d'aluminium 6061 avec un procédé dit semi-automatique (MIG) n'a jamais été reporté jusqu'à maintenant dans la littérature. Nous montrons ici que l'utilisation d'un dérivé du MIG, le MIG CMT (Cold Metal Transfer) permet d'obtenir des cordons soudures sains (sans fissuration à chaud). De plus traitements thermiques ont permis retrouver partiellement ou restaurer totalement les propriétés soudure. Nos résultats sont...
El texto establece un paralelismo entre dos edificios ejemplares de la arquitectura brasileña, específicamente paulista: Facultad Arquitectura y Urbanismo Universidad São Paulo (FAU USP) João Batista Vilanova Artigas, el Sesc 24 Maio Mendes da Rocha. A través análisis basado en fuentes documentales primarias publicaciones los propios autores las obras, se analizan proyectos teniendo cuenta relación forma espacio, discuten elementos estructurantes fundamentales estas obras: Salão Caramelo FAU...
Friction Stir Welding (FSW) is one of the most recent welding processes, invented in 1991 by The Institute. Recent developments, mainly using polycrystalline cubic boron nitride (PCBN) tools, broaden range use FSW to harder materials, like steels. Our study focused on assembly high yield strength steels for naval applications FSW, and its consequences metallurgical properties. main objectivewas analyze transformations occurring during welding. tests were conducted three steels: 80HLES,...
Cet article presente le soudage a l'arc grâce au procede semi-automatique. Il decrit materiel utilise ainsi que les produits d'apport (fil et gaz de protection). detaille modes fonctionnement, leurs utilisations principaux defauts pouvant apparaitre dans soudures. fait part egalement des derniers developpements du qui ameliorent son utilisation ses capacites. Enfin, il rappelle elements d'hygiene securite pour l'arc. En fin d'article, on trouvera exemples preparation bord avec parametres...
A discussões sobre o centro cívico da nova capital do Brasil remontam às comissões técnicas após Relatório Belcher, em 1954, até a Praça dos Três Poderes, projetada por Oscar Niemeyer e Lucio Costa 1957. Resta obscuro estabelecimento de nexos entre arquitetura praça cívica suas expectativas no meio político na opinião pública. Ressente-se textos acerca confronto recém empossado presidente Juscelino Kubitschek Marechal José Pessoa, então responsável pelo planejamento cidade. Jornais época...
At a time when greenhouse gas emissions must be reduced, the use of aluminium alloys is expanding, in particular transportation industry. In order to extend possibilities assembly design, new Metal Inert Gas (MIG) welding processes have been conceived. They work at lower temperatures than usual arc (classic MIG or Tungsten Gas). This study compares four processes, applied 6061 alloy. These weld studied through metallurgical analysis beads. Metallography, micro‐hardness testings, X Ray...
Este texto procura demostrar cómo Le Corbusier, a través de los viajes 1929 y 1936 Río Janeiro, no solo proporciona las bases la arquitectura moderna en el país, sino que también problematiza relación entre espacio construido naturaleza. Frente una realidad completamente distinta aquella del Viejo Mundo, puesto naturaleza tropical se impone, arquitecto franco-suizo ve impulsado jugar partida afirmación-hombre presencia-naturaleza. Tanto Lucio Costa como primera generación arquitectos...
A Igreja da Pampulha, feita em Belo Horizonte 1943, por Oscar Niemeyer, e reconhecida como marco das vanguardas arquitetonicas brasileiras. Seu programa religioso colocava‑se desafio para o arquiteto, pelo primado de simbolos significados que remontavam ao passado colonial catedrais capelas valorizadas pelos intelectuais modernistas, Drummond Andrade, Lucio Costa, Mario Andrade. Entre os anos 1920 1930, intenso debate intelectual acerca heranca do barroco mineiro portadora uma forca...
Com este artigo objetiva-se analisar como a noção de ângulo reto, no interior do universo criativo Le Corbusier, assume distintos aspectos até se cristalizar em um importante conceito seu pensamento sobre relação entre edifício, cidade e paisagem. Partindo livro autobiográfico O poema reto (Le poème l’angle droit ,1951-55), busca-se traçar pontes alguns versos imagens dessa obra trechos seus escritos, conferências desenhos das viagens 1911 1936, abordando sobretudo périplo pelo leste europeu...
Abstract Scholars of the reign Ivan Terrible have only a limited number sources to understand Ivan’s purges during Oprichnina. One most important and commonly used testimonies for period terror, account Livonian captives Johann Taube Elert Kruse, is first time made accessible English-speaking public in critical edition that covers major historiographical issues raised and, when possible, explores reasons behind execution specific individuals.
