Filler rod calculator

[ndg]

I'm still early in my journey with TIG, but a good opportunity to practice has come up. I need to butt weld 2.5mm mild steel sheet., total weld length will be ~16m. Is there a rule of thumb or a calculator for how much filler rod I'm going to need for the job so I can order the right amount? I'm planning to use 1.6mm A15 with a 1.6mm tungsten.

Thanks for any input.

Assume a cross sectional area of the weld, multiply by length to get weldment volume, divide by the volume of a rod that's consumed to get the number of rods.
