Welding Mode Threshold
Compare weld intensity with a caller-supplied keyhole transition threshold.
Description
A welding-mode screen compares average beam intensity with a supplied keyhole transition threshold.
A welding-mode screen compares average beam intensity with a supplied keyhole transition threshold. Its labels reflect that one comparison.1
Compare weld intensity with a caller-supplied keyhole transition threshold.
When to use Welding Mode Threshold
Use this tool to compare weld intensity with a caller-supplied keyhole transition threshold.
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 Welding Mode Threshold 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 beamPowerWatts, spotAreaSquareMeters, keyholeThresholdWPerM2 using the field table and calculation rules, then run the tool.
- Read intensityWPerM2, thresholdRatio, predictedMode. 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 |
|---|---|---|---|
| beamPowerWatts | Beam power (W) | number; minimum: 0 | Required |
| spotAreaSquareMeters | Spot area (m²) | number; minimum: 0 | Required |
| keyholeThresholdWPerM2 | Keyhole threshold intensity (W/m²) | number; minimum: 0 | Required |
Enter nonnegative power, positive area and positive threshold in matching SI units. Return intensity, ratio and keyhole at equality or above, otherwise conduction.
intensity=power/area; ratio=intensity/threshold Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| intensityWPerM2 | Weld intensity (W/m²) | number; minimum: 0 |
| thresholdRatio | Intensity-to-threshold ratio | number; minimum: 0 |
| predictedMode | Predicted welding mode | string; one of "conduction", "keyhole" |

}Limitations and assumptions
No material, speed, absorption, plasma or weld-shape model is supplied.
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.
