The advantages of RFSSW
- High Joint Strength
FSW produces welds with excellent mechanical properties, due to no solidification and a forged, fine-grained microstructure.
- Minimal Distortion
FSW operates at lower temperatures and low heat input compared to fusion welding, welded components have a reduced distortion and residual stress levels, ideal for welded parts with tight tolerances.
- Excellent fatigue behavior
FSW generates a fine-grained forged microstructure in the joint line, which lead to excellent fatigue properties.
- Joining Dissimilar Materials
FSW can join dissimilar materials due to the low heat input high forcing action, including different aluminum alloys, like wrought aluminum to aluminum cast or aluminum to steel or cooper, and even advanced composites,
- Environmentally friendly
FSW produces no fumes, gases, or radiation; no protective gas, additional material or preparation of the joining edges required.
easy to automate and monitor because it´s a mechanic mixing process.
The disadvantage is the remaining exit hole, the high forces during the welding process, require a rigid machine and a tight clamp.
