How this tool works
Inputs, units and where to find them
| Input | Unit | Typical source |
|---|---|---|
| Equal fillet leg size | mm | Equal leg on a 90° joint, not throat size. |
| Total deposited weld length | mm | Total actual weld length; count both sides separately where required. |
| Deposited metal density | kg/m³ | Deposited metal density from a relevant material source. |
| Profile volume factor | × | Justified multiplier over ideal triangular volume; 1 means ideal triangle. |
| Deposition efficiency | % | Deposited mass/consumed filler mass on the same accounting basis, from demonstrated process data. |
Method and formulas
- Ideal area = leg²/2; geometric throat = leg/√2 for a flat-faced equal-leg 90° fillet.
- Volume = area × length × profile factor. Mass = volume/10⁹ × density. Consumed filler = deposited mass/(efficiency/100).
- Example: 6 mm legs over 1000 mm, profile factor 1.1, density 7850 kg/m³ and 95% efficiency gives 0.15543 kg deposited and 0.163611 kg consumed filler.
Limitations
- No strength, required weld size, penetration, distortion or procedure qualification is evaluated. Geometric throat is not a design acceptance value.
- Unequal legs, grooves, concavity and gaps need another section model.
- Flux, stubs, packaging and purchasing waste may require separate allowances on a consistent efficiency basis.
- Default values are worked examples, not recommended settings or material properties.
Typical uses
- weld metal quantity
- fillet volume
- consumable estimate
Who it is for
- Welding estimators
- Fabrication planners
What you get
- Ideal area and geometric throat
- Adjusted deposited volume and mass
- Consumed filler mass
Interpreting the result
- Use approved geometry and measured profile/deposition data.
- Estimate arc time, labour, access and inspection separately.
