Weld Deposition Rate Calculator

Estimate solid-wire deposit per arc hour from feed speed and wire geometry. Enter wire diameter, alloy density, retained efficiency and your production target.

What this calculator does

  • Estimate retained solid-wire deposit per arc hour from feeder settings and measured efficiency.

Formula used

  • Wire area = π × diameter² ÷ 4
  • Gross feed (lb/hr) = wire area × feed speed × 60 × wire density
  • Deposition = gross feed × efficiency ÷ 100
  • Filler loss = gross feed − deposition
  • Shortfall = target deposition − calculated deposition

Inputs explained

  • Wire Feed Speed: Measured solid-wire feed speed or verified feeder setting.
  • Solid Wire Diameter: Circular solid-wire diameter from the consumable data sheet.
  • Wire Density: Solid-wire alloy density from material data.
  • Deposition Efficiency: Retained mass divided by consumed wire from a matched trial.
  • Target Deposition Rate: Required retained filler per arc hour from the production plan.

How to use the result

  • Best suited to Solid-Wire feeder Planning, retention efficiency comparison.
  • Tubular and cored wires require their manufacturer’s lineal mass data. The result is per arc hour; handling and setup reduce shift output.

Current U.S. benchmarks

  • The producer price index for steel mill products stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. Quotes priced off last quarter's material cost miss this move.
  • Industrial electricity averages 9.77 cents per kWh across the U.S. (EIA, Jul 2026), up 4.7% from a year earlier. Energy-intensive steps carry this directly into unit cost.
  • U.S. iron and steel import customs value ran $2.2B in Aug 2026 (Census International Trade). The U.S. ran a trade deficit of $0.6B in the category that month. This dollar total mixes price, quantity, product mix, origin, and timing; it does not measure physical import volume or prove a tariff or reshoring effect.
  • The U.S. has 53,790 fabricated metal products establishments employing about 1,441,471 workers (Census County Business Patterns, 2023).

Common questions

  • Can I use this for flux-cored wire? No. A tubular wire does not have a uniform solid cross section. Use its manufacturer’s measured mass per length and process deposition data.
  • Why does wire diameter have a large effect? Circular wire area varies with diameter squared. At the same feed speed, density and efficiency, a larger diameter feeds and deposits more mass per arc hour.
  • What deposition efficiency should I enter? Use a matched trial or applicable consumable data. Retained mass divided by consumed wire captures clipping, spatter and other losses on the same consumption basis.
  • Does this predict pounds deposited per shift? Only after you apply measured arc-on hours for that shift. The displayed rate assumes wire feeds during welding and excludes handling, setup and downtime.
