Electrode Consumption Calculator
Estimate electrode and wire consumption based on weld volume and process efficiency.
Typical Deposition Efficiencies
| Process | Efficiency | Notes |
|---|---|---|
| SAW | 95-99% | Highest efficiency |
| GMAW (Solid) | 93-98% | Minimal spatter loss |
| GTAW | 95-100% | Manual filler addition |
| FCAW-G | 82-88% | Flux loss ~15% |
| FCAW-S | 78-85% | Higher spatter |
| SMAW | 55-70% | Stub + coating loss |
Understanding Electrode Consumption
Consumption Formula
Electrode Required = (Weld Volume x Steel Density) / Deposition Efficiency x (1 + Waste Factor)
Factors Affecting Consumption
- Deposition Efficiency: Percentage of electrode that becomes weld metal
- Spatter Loss: Metal lost as spatter during welding
- Stub Loss (SMAW): Unusable electrode stub (typically 50mm)
- Flux Loss (FCAW): Flux core does not contribute to weld metal
Waste Factor Guidelines
- 5%: Automated/mechanized welding, minimal waste
- 10%: Standard manual welding, good practice
- 15-20%: Field conditions, difficult positions
- 25%+: Severe conditions, rework expected
