creates heat through friction under pressure.
• Conventional FSW pushes a pin tool
against a robust anvil, generating
frictional heat by applying axial force.

• Self-reacting FSW (SR-FSW) uses a
pin tool with external shoulders that
are squeezed together using
NASA-patented technology, generating
frictional heat by exerting pinch force.
