The unique features of the process that proves its benefits over other manufacturing
processes are as follows:
• Single-step process to create a channel.
• Different positions and dimensions can be attained along the length of the channel
by FSC.
• Repeatability and stability in maintaining the dimension of the channel are ensured
by the process.
• Environmentally friendly process using no consumables and no coolant.
• Fine-grain size at the NZ of the channel enhances the ceiling strength of the
channel.
• High productivity.
4.5 FSC Process
As mentioned previously, the FSC process is derived by creating the wormhole defect
with low heat generation and the purposeful material extraction from the workpiece
during FSW. By controlling the process parameters, this wormhole defect can be
made throughout the plate resulting in a continuous channel. Since FSC is a derivative
of the FSW process, thus the main steps of the process are almost similar to that of the
FSW. The main feature that makes this process unique is the absence of plunging off
the shoulder onto the workpiece. The FSC process can be understood from Fig. 4.6.
The initial step of FSC is the insertion of the pin with a given ω and vertical
feed. The main difference in this step of FSC with that of FSW is the provision of
