1. Towards Qualification of Friction Stir Welding to AA5083-O and AA5052-O Aluminum Alloys
Friction Stir Welding (FSW) is an excellent alternative for joining dissimilar and similar materials in comparison to conventional welding processes. In this sense, this work aims at qualifying FSW to similar AA5083-O and AA5052-O aluminum alloys, with 6.35 mm thickness, in a CNC machining center. Therefore, four welding experiments were undertaken. At first

2. Thermal Dissipation Effect on Temperature-controlled Friction Stir Welding
Resumo Durante a Soldagem por Fricção linear (FSW) de geometrias complexas, a dissipação térmica, induzida por características geométricas ou pelo ambiente circundante, desempenha um papel importante na qualidade final da junta. Para garantir uma qualidade consistente em condições diferentes é necessário a adaptacão de parâmetros durante o proce

3. 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

4. Optimization of Multiple Performance Characteristics of Friction Stir Welded Joint with Grey Relational Analysis
In the present work, multi-objective optimization of the input welding parameters influencing the quality of weld joint of AA 5052 H32 aluminium alloy by FSW process is investigated using response surface methodology and grey relational analysis. The quality of the welded joint is measured based on the higher value of tensile strength and hardness of the joi

5. Estudio de propiedades mecánicas locales de uniones soldadas por fricción agitación (FSW) en AA6061-T6 mediante Small Punch Test (SPT)
ABSTRACT Friction Stir Welding (FSW) is a solid state process that has reach a strong technological impact in welding of aluminum alloys. Among its advantages, it may include the ability of joining materials that are difficult to weld by fusion. In welding of heat treatable aluminum alloys, some degradation in metallurgical properties is observed, so welds s

6. Comportamiento frente a la corrosión de uniones soldadas por fricción agitación de AA7075-T651: Evaluación galvánica
ABSTRACT Friction Stir Welding (FSW) is a novel solid-phase welding process, which has proved to have a great potential for the realization of welded joints in materials with poor weldability such as heat-treatable aluminum alloys. The aerospace industry has incorporated this process for the manufacture of structural elements, using known high strength alloy

7. Effect of Heat Input on the Mechanical Behaviour of Al-Cu FSW Lap Joints
Dissimilar Al-Cu joints are desirable due to the combination of the good electrical and thermal properties of copper with the economic advantages of aluminium. However, different chemical, mechanical and thermal properties turn dissimilar welding into a challenge with traditional fusion welding techniques. Friction stir welding appears to be a good alternati

8. Effect of Process Parameters on Microstructure and Mechanical Properties of Friction Stir Welded Cast Nickel Aluminum Bronze Alloy (C95800)
In the present study, Friction Stir Welding (FSW) of Nickel Aluminum Bronze (NAB) alloy was carried out by varying the axial load, rotation speed and welding speed rate. Micro-structural analyses of these samples revealed the different grain sizes and shapes of the various zones. Hardness and tensile strength tests were carried out for the samples welded at

9. Thermomechanical Modelling of FSW Process Using a Cylindrical Tool in an Aluminum Alloy Alclad AA 2024-T3
The Friction Stir Welding Process (FSW/P) is an innovative technique to join metals using the plasticity, not occurring the melting. It was initially applied in aluminum alloys, but recently it has been extended to other materials, for example, copper, steel alloys, polimers and others. In this work it is analyzed the thermo mechanical modelling of the energ

10. Influência do Tipo de Liga de Alumínio na Formação de Defeitos em Soldaduras em Chapas Finas Unidas por Friction Stir Lap Welding
Resumo No presente trabalho são comparadas as soldabilidades de duas ligas de alumínio: a liga AA6082-T6, tratável termicamente, e a liga AA5754-H22, não-tratável termicamente. Foram produzidas soldaduras, em chapas finas, pelo processo Friction Stir Lap Welding (FSLW). Concluiu-se que apesar da utilização dos mesmos parâmetros e procedimentos de so

11. Dimensionamento de um Sistema Robotizado para a Soldagem pelo Processo Friction Stir Welding
Resumo: A primeira aplicação de um robô de soldagem pelo processo FSW (Friction Stir Welding) foi apresentada ao público em Gotemburgo, Suécia, no ano 2000, durante o Friction Stir Welding Symposium por dois diferentes grupos de pesquisa. Um grupo utilizava um robô antropomórfico modelo ABB IRB-6400 combinado a um motor elétrico de 220W e o outro um
