No. Nothing like friction. There is no fusion line. The profile is smooth. Note – friction grain flow is 90 degrees. Grain flow of solid-state is laminar, and smooth.

If it is easy, we’ll be buying this new quality from offshore companies. This singular solid state weld is already classified under ASME IX Code Case.

This technique is used in automotive axles for over a decade. Federal Mogul / Tenneco won the 2016 Pace Award for joining diesel cylinder heads using solid-state. Note: one cylinder is spun on with curls, the other joined using solid-state with smooth profile.

Patents 1 & 2, the original aim was to help improve pipeline weld integrity. Further patents published and pending open new branches of manufacturing. Solid-state can be applied from tubular to flat geometry.

FuseRing is cooperating with Sorsys Technologies to build demo equipment. We expect sample welds in late 2022.
