Filler Metal Consumption Calculator
Convert deposited weld weight into the amount of filler wire or electrode you need to buy, by process efficiency.
How it works
Filler purchased = deposited weight / deposition efficiency.
Worked example
10 lb deposited at 90% efficiency (GMAW): 10 / 0.90 = 11.1 lb of wire.
When to use it
- Typical deposition efficiency: SMAW ~65%, GMAW ~90%, FCAW ~85%, SAW ~99%.
- Efficiency covers spatter, stub loss, and slag.
