Welding/Soldering/Cutting Articles TRIZ Cases

Asymmetric amorphous region depths prevent laser scribing overlap, reducing substrate cracking while maintaining mechanical strength.

Laser modification creates internal cracks along the c-plane, reducing ingot discard by 70% and improving production efficiency.

Alumina coated cemented carbide tool resists oxidation and wear during high temperature steel welding.

A friction stir welding tool uses a rotatable shoulder to maintain surface contact and plunge depth while the pin mixes material.

A rotating friction tool bonds flat workpieces by rubbing the second surface without penetrating.

A bonded article uses a heat capacity increasing portion to regulate plastic flow during solid-phase joining of dissimilar metals.

Cladding mode strippers extract back-reflected radiation for automated focus adjustment, resolving measurement difficulties in high-brightness laser processing.

An arcuate tip end protrusion on a vehicle door inner member distributes electric current during resistance welding to ensure stable joint formation.

A laser heating and rolling device joins metallic overlay elements to substrates in a material-bonded manner.

Blue-violet laser radiation selectively damages and disintegrates optical fiber coating, resolving mechanical damage risks during field stripping.

Heated softer metal flows into a recessed first member during rotation, equalizing temperature distribution and preventing unstable fixation.

Branching a single laser beam into multiple paths via polarization optics enables wide groove formation in one pass, eliminating the need for multiple passes.

Copper intermediaries reduce zinc vaporization during brass welding, enabling deep, gastight joints with lower energy input.

Controlled expansion adjusts the undulation wavelength ratio outside critical ranges to prevent buckling under seismic or permafrost loads.
