How the welding time & cost calculator works

Arc time is length divided by entered travel rate. Divide by arc-on fraction, convert to hours and add one setup allowance for elapsed crew time. Multiply by the combined crew hourly value for labor cost.

Gas volume is arc minutes times the entered gas-flow factor; filler mass is entered independently. Labor, filler and gas charges round separately to cents before totaling. Zero length suppresses the whole event.

Gas covers arc-on flow only; pre/post flow and leakage need a separate included allowance. No safe welding procedure, travel rate, gas flow, equipment setup or ventilation is recommended.

Worked example

Ten metres at 0.3 m/min is 33.333 arc minutes. At 25% arc-on plus 0.5 setup hour, labor is 2.7222 hours, worth $136.11 at $50/h. Add $16 filler and $6.67 gas for $158.78. At $60/h, total becomes $186.

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 Shielding-Gas Quantity

    Combine arc and pre/post-flow time at an entered flow rate, add a volume allowance and round to whole usable-cylinder quantities.

  • Milling Feed Rate & Travel Time

    Multiply entered RPM, effective teeth and chip load, then estimate ideal feed-travel time for a defined path and number of passes.

  • Weld Filler Consumption

    Convert a specified deposited area into filler mass, declared loss allowances and whole packs.
