“…Wear is caused by excessive contact between the tool and welded material. The tool geometry has a significant effect on its resistance to erosive wear [3]. Without a doubt, the topics covered in the articles are valuable from the weld quality point of view, which should be characterized by identical strength parameters across the entire life of the tool.…”

The article concerns the issues of tool wear effect on the quality of a friction stir welding joint quality. The experiment used aluminum alloy 7075 T6 sheet metal, which is used primarily in the aerospace industry. 1.0mm and 0.8mm thick lap joints were tested. Tool wear was determined based on multiple readings on a multisensory machine. The tool wear evaluation was done on the basis of a static tensile strength test and metallographic sections of the joints. The pin of the tool works in more demanding conditions and is more exposed to friction. This results from tooling operations performed at full depth dive in the jointed material. When also considering the small dimensions of the pin such as the diameter and the great forces occurring in this process, it is easy to see why this element is most susceptible to tool wear. The welding process causes the tool to undergo friction wear, which is the cause of reduced tool dive depth in the jointed material. As a result, it is paramount to constantly control the tool extension to achieve the desired quality parameters of the joint. After creating 200m of joints, a decrease in the strength of joints was observed as well as the repeatability of the results connected to a change in the stirring conditions in the material. The change in joint strength and tool wear is also confirmed in the metallographic analysis, which states that the continued degradation of the tool makes it subject to a decrease in size of the characteristic sizes of the thermoplastic zone that is the main determining factor of the joint strength.

“…A MTS iSTIR BR4 friction stir welding machine was used for welding the box. Because SiCp/Al-MMCs is a quite wear resistant result from SiC particles existing [15], the material and the shape of FSW tool need to be considered carefully. In this research, the FSW tool is made from the material of wear resistant WC-Co. To improve the FSW tool wear resistance, a cone shape tool is used in experiment.…”

Using friction stir welding, the electronic container box and lid made from aluminium matrix composites with reinforcement of SiC particle (15 vol% SiCp/Al-MMCs) was welded successfully with T-joint. The temperature distribution of box during the process, mechanical property and microstructure of the joint as well as gas tightness of welded box was investigated. The experimental results indicated that the satisfactory T-joint can be obtained under appropriate friction stir welding parameters. During the welding process, the bottom center, which was used to place the electronic component, reached a quite lower temperature of 100°C. That can ensure safety of components in the box. After the welding process, the microstructure in stir zone was better than in base material due to the refining and homogeneous distribution of the SiC particles. The experimental results showed that the electronic container box after friction stir welding had gas tightness. The He-leakage rate was under 10-8 Pa•m3/s.

“…Además, se analizó también la FSW en juntas traslapadas de aluminio y acero utilizando cinc como metal de relleno colocado entre las láminas a soldar [12]. En general los estudios se enfocan en su mayoría en materiales disímiles [13]. Sin embargo, existen pocos datos para juntas a tope para láminas de aluminio 6061 T6 unidos con FSW [14].…”

Existe una clara tendencia en la industria del transporte para la reducción de peso en los componentes estructurales con el objetivo de mejorar la eficiencia del consumo energético. Los materiales utilizados para este propósito son aleaciones de aluminio y magnesio; pero al utilizar el método de soldadura por fusión, las juntas presentan bajas propiedades mecánicas en comparación con el material base. La soldadura por fricción es una alternativa para unir en estado sólido estos materiales y ha mostrado una buena compatibilidad y alta eficiencia. El objetivo de este trabajo es el análisis del efecto de la velocidad de soldadura sobre la resistencia mecánica de las juntas para la aleación de aluminio 6061 T6 soldadas por FSW. Del estudio se obtiene curvas de resistencia a la tracción, doblado guiado y dureza en la soldadura mostrando un mejor comportamiento en probetas unidas a mayor velocidad de rotación de la herramienta.
