Welding Rod Consumption Calculator

Divide the deposited weld metal weight by the deposition efficiency to get electrode pounds, then divide by the weight of one rod and round up. For 5 lb of metal at 65 percent with 0.1 lb rods, that is about 77 rods.

It is the share of electrode that becomes weld metal, roughly 60 to 70 percent for stick because the stub end, spatter and slag are lost. The default 65 percent is a documented mid-range rule of thumb.

It depends on diameter and length, but a single stick rod is often near 0.1 lb. Weigh a rod or check the box count per pound and adjust the rod weight field for an accurate count.

You cannot use a fraction of a rod, so the result is rounded up to the next whole electrode. A small tolerance keeps counts that land exactly on a whole number from rounding up by mistake.

Use a weld metal volume and weight calculator, or multiply the joint cross section area by length and density. Enter that deposited weight here to size your electrode order.
