How the weld filler consumption calculator works

Area in mm² times length in metres divided by one million gives deposited m³. Multiply by density for kilograms. Divide deposited mass by deposition efficiency, then add the separate additional waste allowance.

Required filler mass divided by pack mass rounds upward to whole packs. Purchased surplus is inventory. Avoid counting the same loss through both deposition efficiency and extra waste.

The cross-section must come from a qualified drawing or procedure. No joint design, structural weld size, filler selection, welding setting, strength or suitability is determined by this quantity calculation.

Worked example

A 25-mm² area over 10 m at 7,850 kg/m³ deposits 1.9625 kg. At 90% deposition efficiency plus 10% extra waste, allowance is about 2.3986 kg, requiring three 1-kg packs at $8, or $24. Doubling length needs five packs.

Sources and assumptions

The source material explains the underlying calculation or pricing structure. Entered prices, costs, schedules and scenario choices are your assumptions; this tool does not obtain supplier quotes or predict actual results.

  • Turning Machining Time

    Time repeated identical turning passes from entered constant RPM, feed and travel allowances.

  • Welding Time & Cost

    Separate arc-on time, elapsed crew time and entered consumable costs.

  • Production Capacity

    Estimate whole starts and expected good-unit capacity using observed running cycle, availability and yield.

  • Machining Batch Cost

    Spread setup and whole expected-start costs over a required good-part batch.
