Friction Stir Welding (FSW) is a solid-state welding method that has diffusion and different metal structures can blend well. stir weakness, one of which the lack flexibility process only carried out on side plate being welded, so it not applied thick materials. Double friction double working in to be welded subjected from two tools opposite sides. In DS-FSW process, dimensions geometry tool pin greatly affect quality joint. This study determine mechanical properties corrosion rate aluminum...
The utilization of Aluminum hollow panels enhances structural strength while simultaneously ensuring a lightweight and efficient use materials. During their application, these necessitate welding process that is susceptible to porosity due the disparity in hydrogen gas solubility between liquid solid aluminum. Solid-state techniques, such as Friction Stir Welding (FSW), have proven be effective appropriate solutions for overcoming this issue. However, thickness panels, FSW unfeasible it...
Friction Stir Welding (FSW) is commonly used in transportation industries but faces challenges when joining thick plates. To address this, double-side FSW (DFSW) has been introduced, involving two steps: on one side, flipping the plate, and then opposite side. However, this process time-consuming. overcome a one-step DFSW technique was developed, where tools simultaneously operate both sides. This study aimed to investigate impact of tool rotation speed fatigue crack growth rate AA6061-T6...

Underwater welding is the process of connecting two similar or different metals which are carried out underwater. This applied in various construction engineering materials both on land and underwater environments such as ship construction, oil gas mining middle sea nuclear power plants. Material greatly influences method suitable for process. It will affect evolution microstructure mechanical properties material. So, it results welded joint.
Aluminium is a light metal that widely used in industry because it has good machinability, corrosion resistance resistance, and high ductility. In its application to the vehicle structure, welding process requires connection process. However, aluminium several problems thermal conductivity, large coefficient of expansion, specific gravity low melting point. So, this study aims determine difference fatigue crack growth rate welded joints from different environmental conditions such as air...
