Wobble Weld Coverage
Estimate sinusoidal wobble path factor, coverage width, and cycle density.
Description
Wobble-weld coverage combines forward travel with a transverse oscillation.
Wobble-weld coverage combines forward travel with a transverse oscillation. The path factor here is a slope-based approximation rather than an integrated sinusoidal arc length.1
Estimate sinusoidal wobble path factor, coverage width, and cycle density.
When to use Wobble Weld Coverage
Use this tool to estimate sinusoidal wobble path factor, coverage width, and cycle density.
Prepare the optical measurements, geometry, fitted coefficients or caller-selected thresholds requested. Confirm wavelength, radius/diameter, pulse-width, angle and unit conventions before running the calculation.
How to use Wobble Weld Coverage and understand its results
- Prepare the optical measurements, geometry, fitted coefficients or caller-selected thresholds requested. Confirm wavelength, radius/diameter, pulse-width, angle and unit conventions before running the calculation.
- Enter travelSpeedMmPerSecond, wobbleAmplitudeMillimeters, wobbleFrequencyHertz, spotDiameterMillimeters using the field table and calculation rules, then run the tool.
- Read pathLengthFactor, effectiveCoverageWidthMillimeters, wobbleCyclesPerMillimeter. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| travelSpeedMmPerSecond | Travel speed (mm/s) | number; minimum: 0 | Required |
| wobbleAmplitudeMillimeters | Wobble amplitude (mm) | number; minimum: 0 | Required |
| wobbleFrequencyHertz | Wobble frequency (Hz) | number; minimum: 0 | Required |
| spotDiameterMillimeters | Spot diameter (mm) | number; minimum: 0 | Required |
Enter positive travel speed and nonnegative amplitude, frequency and spot diameter in the specified mm/s, mm and Hz units. Return path factor, coverage width and cycles/mm.
slope=2πAf/v; factor=sqrt(1+slope²); width=d+2A; density=f/v Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| pathLengthFactor | Wobble path-length factor | number; minimum: 1 |
| effectiveCoverageWidthMillimeters | Effective coverage width (mm) | number; minimum: 0 |
| wobbleCyclesPerMillimeter | Wobble cycles per travel millimeter (cycles/mm) | number; minimum: 0 |

}Limitations and assumptions
No weld quality, thermal history or exact average path length is predicted.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Welding Mode Threshold: Compare weld intensity with a caller-supplied keyhole transition threshold. For a complementary task, use Multipass Weld Fill: Compare multipass weld joint volume with deposited fill-wire volume.
