Multipass Weld Fill
Compare multipass weld joint volume with deposited fill-wire volume.
Description
Weld fill budgeting compares a geometric joint volume with total deposited wire volume.
Weld fill budgeting compares a geometric joint volume with total deposited wire volume. Pass count divides deposited volume rather than multiplying wire feed.1
Compare multipass weld joint volume with deposited fill-wire volume.
When to use Multipass Weld Fill
Use this tool to compare multipass weld joint volume with deposited fill-wire volume.
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 Multipass Weld Fill 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 seamLengthMillimeters, jointAreaMm2, wireDiameterMillimeters, wireFeedLengthMillimeters, depositionEfficiency, passCount using the field table and calculation rules, then run the tool.
- Read requiredFillVolumeMm3, depositedVolumeMm3, fillRatio, volumePerPassMm3. 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 |
|---|---|---|---|
| seamLengthMillimeters | Seam length (mm) | number; minimum: 0 | Required |
| jointAreaMm2 | Joint cross-sectional area (mm²) | number; minimum: 0 | Required |
| wireDiameterMillimeters | Fill-wire diameter (mm) | number; minimum: 0 | Required |
| wireFeedLengthMillimeters | Total wire feed (mm) | number; minimum: 0 | Required |
| depositionEfficiency | Deposition efficiency | number; minimum: 0; maximum: 1 | Required |
| passCount | Weld pass count | integer; minimum: 1 | Required |
Enter positive required-volume dimensions, nonnegative wire diameter/feed, efficiency 0–1 and positive integer passes. Return required/deposited volumes, ratio and deposited volume per pass.
required=seamLength×jointArea; deposited=π(wireDiameter/2)²×feedLength×efficiency Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| requiredFillVolumeMm3 | Required fill volume (mm³) | number; minimum: 0 |
| depositedVolumeMm3 | Deposited wire volume (mm³) | number; minimum: 0 |
| fillRatio | Deposited-to-required fill ratio | number; minimum: 0 |
| volumePerPassMm3 | Deposited volume per pass (mm³) | number; minimum: 0 |

}Limitations and assumptions
Feed length is total across passes. No density conversion, shrinkage, bead shape or weld-quality assessment is included.
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 Wobble Weld Coverage: Estimate sinusoidal wobble path factor, coverage width, and cycle density.
