emperical relation for deposition rate calculation

By j a c o b Date 06-29-2018 11:08

If I'm welding SAW, let's say I picked an electrode, as well as the current power and the voltage, the electrode extension as well as its diameter, the travel speed is known as well. is there any empirical relation that combine all of these inputs in order to give the deposition rate?
Thanks,
Jacob

Jacob, all of that info is on your electrode manufacturer's data sheets. It is usually listed as pounds per hour. Although you should take in account for a small amount of waste(spatter, slag, etc), which is also on the data sheets.

Deposition rate formula -

WFS x Dia x Dia x Efficiency Factor x 13.33 = DR

WFS = Wire Feed Speed
Dia = electrode diameter
Efficiency Factor = Varies depending on electrode and transfer mode (SAW with solid wire should be .98)
13.33 = a formula constant for carbon steel

that's much appreciated, sir.
