An annular friction surface and counter-thread conveying screw raise friction stir welding speed while reducing pin breakage from material variations.

A low h/w bonding part and bottom-plate screw layout improve horn tip fixation, avoid resonance loosening, and limit frictional heat.

An arch-shaped welding head redistributes pressure during ultrasonic vibration to prevent cracks and breakage in thin workpieces.

A faster-rotating pin and slower shoulder maintain heat balance in friction stir welding, enabling defect-free welds at higher travel speeds.

A profiled FSW head piece uses stepped end faces and a slanted shoulder to guide plasticized material, seal gaps, and limit crevice corrosion.

A head-mounted rotating tool trims weld-line roughness and burrs during friction stir welding, cutting post-processing time and improving surface quality.

Relative displacement and stop-position sensing quantify sonotrode and anvil wear, reducing manual checks and enabling predictive maintenance.

A dual-surface probe wall constrains burr spread during friction stir spot welding, preventing electrocoating defects and extra deburring.

Inclined clamp and backing concaves let material accumulate during double-acting friction stir spot welding, forming thicker, stronger joints.

Variable ridge and valley geometry in a friction stir welding probe boosts stirring force while reducing thread wear and tool replacement.

A spring-biased sleeve around the sonotrode adds localized clamping and cooling to improve weld quality without separate clamp plates.

Sound or ultrasonic vibration drives atomic diffusion between a metal rivet and hole wall, enabling stronger fixation without a through hole.

Variable and fixed Z-axis correction modes keep friction stir welding load within range, improving weld quality without slow response.

A retractable pin in a compact friction stir welding head fills the exit hole, leaving a planar surface on machine-tool welds.

Opposed probe-free rotating tools with shaped end faces improve thickness-direction plastic flow, joint quality, and welding speed.

A ring-shaped receiving surface and discharge holes redirect friction stir welding waste away from the pin holder to reduce deformation and maintenance.

A flexing weld pad uses compliant legs and a bridge to fit flat, rounded, or uneven substrates, reducing pad variants without weakening weld contact.

A threaded adjustable pin and variable-aperture shoulder let one friction stir welding tool fit different wall thicknesses while maintaining weld quality.

A ring-shaped receiving surface and through hole use centrifugal force to expel welding waste, limiting pin wear, overheating, and deformation.

Probe-free opposing tools with shaped hard end faces even out heat and shearing stress to strengthen steel welds and raise welding speed.

Rotating pin and shoulder stages soften and expel sealant before stirring, preserving corrosion protection while maintaining weld quality.

A two-pass FSW sequence uses opposite tool rotation to re-weld exit holes and partially unwelded regions for more homogeneous joints.

An oil film on pin, shoulder, or clamp surfaces suppresses weld material agglutination and enables more continuous friction stir spot welding.

Adaptive and fixed Z-axis correction modes help friction stir welding recover quickly from load deviation without overshoot or weld quality loss.

An internal electric-cylinder retraction mechanism pulls back the stirring needle to remove end-weld keyholes and simplify spindle modularity.

Dual sealing gaps and an accessible receiving chamber trap and remove doughy weld material to extend friction spot welding tool life.

An annular friction surface and counter-thread conveying screw raise friction stir welding speed while reducing pin breakage and self-heating.

A flexible manifold seals to irregular structural surfaces and pressure-injects bonding material into cracks without drilling or vacuum assistance.

Sensor-controlled portable friction welding attaches fixtures without drilling, tapping, or open-arc hazards while limiting coating and substrate damage.

Rotating pin and shoulder preheat and press sealed workpieces to soften and push sealant out, preserving weld quality and corrosion resistance.

A retractable pin lets the friction stir welding head fill the exit hole, producing a smooth weld surface on standard machine tools.

Measured ridge-line routing offsets the rotating tool to join uneven-height metal members while preventing burrs, undercuts, and root flaws.

Opposed rotating tools on both sheet sides balance heat and plastic flow, enabling faster friction stir welding with fewer defects and stronger joints.
