Welding/Soldering/Cutting Articles TRIZ Cases

An acousto-optic deflector minimizes thermal loading on optical components while maintaining high throughput during dense workpiece feature processing.

Dynamic laser pulse control adjusts energy and width to overcome fixed parameter limits, improving hole quality and throughput.

A welding mode determination device compares light emitting images captured in infrared and short wavelength visible light regions to identify the active laser beam welding process.

An interposed bearing contacts a fixed correction member to align the welding tool, reducing unnecessary displacement and device complexity.

A zinc coating mediates resistance spot welding between steel and aluminum workpieces.

Friction stir welding joins rolled aluminum edges to create a lightweight door beam that resists side impact cracking without the weight penalty of steel.

Introducing titanium filler wire ahead of the laser beam traps nitrogen gas, reducing porosity and increasing weld strength.

Spatial light modulator controls converging point distance to prevent leakage light interference and front face damage during high-density laser machining.

A laser beam removes front and rear coatings on transparent lighting components, enabling complex dual-face recess geometries without mechanical masks.

Single-step aging at 140-190°C eliminates complex two-step processes, restoring hardness recovery and tensile strength in welded aluminum alloy joints.

Dynamic optical axis deflection distributes thermal energy across sequential positions, preventing electrode melting during high-frequency laser ablation.

Ultrasonic joining creates scarf joints between thick non-weldable aluminum sheets using multiple passes and plugs, avoiding heat-affected zones.

Pulsating DC current prevents premature solidification of molten steel weld pools, eliminating soft shell regions and ensuring uniform nugget hardness.
