We'll assume you're ok with this, but you can opt-out if you wish. FSW has changed the way components for aerospace, defense, shipbuilding, transportation, medical, and electronics are fabricated, and its scope is expanding to more industries and applications. The pin lengths in the six experiments were 2. The hooking also showed a significant influence on the weld strength, as shown in Figure 6. Good surface contact with the workpiece must be maintained constantly.
Reluctance Sensor for Penetration Depth Control in Friction Stir Welding
A study on parameter optimization in the circumferential GTA welding of aluminium pipes using a semi-analytical. It is interesting to note that tool design D produced welds that had increasing elongation with increasing travel speed. If you have the appropriate software installed, you can download article citation data to the citation manager of your choice. Three welding tools were studied in Phase II in order to evaluate differences in shoulder geometry and material. Widespread commercial applications of friction stir welding process for steels and other hard alloys such as titanium alloys will require the development of cost-effective and durable tools. The Phase II welding tools used a frustum-shaped pin profile, each with three equally spaced flats machined into the profiled surface, and a scroll or spiral shoulder profile. FSW is also found in modern shipbuilding, trains, and aerospace applications.
Friction Stir Welding
Additional designs include the Triflute and Trivex series. The process is much more energy-efficient than arc or laser welding, so energy consumption can be reduced by 60 percent to 80 percent. Two types of joints were evaluated: These competing demands lead onto the concept of a "processing window": Figure 8 shows the plates in the prototype tooling during the initial plunge into the workpiece.
