WebFSSW is a variant of FSW and works by rotating, plunging and retracting a non-consumable tool into two workpieces in a lap-joint configuration to make a “spot” weld. During FSSW there is no traversing of the tool … WebThe flat friction stir spot welding uses two different tools (a tool with a pin and a pinless tool) for producing the FSSW joint and refilling the formed keyhole [23,24]. In the first step, a specially designed back plate with a predrilled dent is utilized to yield a protuberance on the bottom side of the joint.
