Bessel-Vortex pulse shaping enables fast drilling of large through-holes in transparent materials while avoiding hot spots and filamentation.

A cutout end tab lets the FSW tool preheat and align at the joint start, reducing start-end defects and rib interference in hollow workpieces.

Suppressing zeroth-order diffraction lets off-axis laser interference form finer periodic line structures with less radiation loss and thermal load.

Automatic laser marking cuts protective film at common parts, reducing manual removal time in sheet metal processing.

Controlled Ceq and post-weld tempering create iron-based carbides in the HAZ, raising cross tensile strength in high-strength steel joints.

A picosecond-nanosecond laser sequence polishes ceramics to submicron roughness while limiting heat damage, cracks, pores, and material removal.

By splitting one laser into independently steered beams, this case improves substrate processing precision and throughput without added source complexity.

Vision-guided syringe feeding and heater-based melting automate solder paste application for higher welding throughput and more consistent deposition.

Reverse laser scanning builds taller weld protrusions independent of plate thickness, creating vapor-release gaps that suppress blow holes.

A clawed holder and imaging reference improve friction stir welding alignment while preventing member shift and upper-surface damage.

Laser ablation shapes CMC sheets without mechanical force, reducing fiber wear and deformation while maintaining tight cut tolerances.

A rotating textured mandrel continuously refines tubular stock into finer equiaxed grains, then converts it into sheet with lower processing burden.

Controlled current stages grow, solidify, and re-melt the weld pool to overcome aluminum oxide and thermal gradients for stronger steel-aluminum joints.

A hard tip fused to a tougher firing pin body reduces nail gun wear and deformation while preserving impact resistance.

Automated spiral winding and fiber laser seam welding speed boron-coated detector straw production while maintaining precise seam quality.

Transmitted laser pulse sensing sets space-resolved shutoff points, keeping tear lines uniform despite workpiece thickness variation.

Adjustable beam profiles split laser energy into controlled patterns, raising ablation rate while preserving precision and low burr formation.

Optimized adjacent nugget spacing in laser welding limits solidification crack connection while improving peel strength in tight weld areas.

Single-side pin insertion in friction stir joining balances heat input for dissimilar metals, cutting burrs, tool load, and bond defects.

Tool temperature feedback sets plunging force during serial friction stir spot welding to prevent underfill and preserve weld surface quality.

Resonant CW laser modulation amplifies capillary waves to eject molten metal with less energy, plume absorption, and overheating.

A hard firing pin head fused to a tougher body reduces nail gun wear and deformation while maintaining impact resistance.

Enclosed friction welding joins dissimilar metal members firmly in a mold cavity, improving fixation stability while reducing machining cost.
