In-situ Intelligent Monitoring and Data Comparison of the FSW Process
Advantages of Friction Stir Welding (FSW)
High-quality welding:
It avoids defects such as porosity and cracks found in traditional welding, resulting in high joint strength and a minimal heat-affected zone.
Wide range of material applicability:
Suitable for welding various metals, including aluminum, magnesium, copper, titanium, steel, and other metals, as well as dissimilar metals.
Green and eco-friendly:
No filler wire or shielding gas is required, and no fumes are produced during welding, making it environmentally friendly.
high efficiency:
Fast welding speed, high production efficiency.
Friction Stir Welding (FSW) has significant applications in the following fields:：
- Automotive Industry: Particularly in the electric vehicle sector, for welding components such as battery trays, heat exchangers, and power electronics assemblies.
- Aerospace: For welding aircraft structural components and engine parts to enhance weld strength and durability.
- Rail Transportation: Suitable for welding components like car body panels and bogies.
- Other Fields: Also applicable in shipbuilding, consumer electronics, nuclear energy, and other sectors.
