Welding & Fabrication calculator

Duty Cycle Calculator

Calculate welder duty cycle from arc-on time and total cycle time. Two counts and a target give you a rate plus how far you are from where you need to be.

What this calculator does

  • Calculate welder duty cycle from arc-on time and total cycle time.
  • Use it when duty cycle in welding and fabrication needs a clean rate and gap-to-target you can put on a tier board.
  • Turns duty cycle count, total duty cycle population, target duty cycle rate into a rate for duty cycle in welding and fabrication.

Formula used

  • Duty cycle rate = duty cycle count ÷ total duty cycle population × 100
  • Duty cycle gap to target = duty cycle rate - target duty cycle rate

Inputs explained

  • Duty cycle count: Enter the number of defects, passes, claims, shortages, conforming units, or events being measured.
  • Total duty cycle population: Use the matching inspected, produced, tested, shipped, sampled, or installed population for the same period.
  • Target duty cycle rate: Enter the KPI, specification, contract target, quality target, or internal control limit.

How to use the result

  • Use it when duty cycle in welding and fabrication is being reviewed against a KPI.
  • Trend matters more than a single snapshot; pull the result for the last several periods before you act.

Common questions

  • What problem does this duty cycle calculator solve? Calculate welder duty cycle from arc-on time and total cycle time. You get a rate you can defend before quoting, scheduling, or sign-off.
  • Which inputs change the rate the most? duty cycle count, total duty cycle population, target duty cycle rate usually move the rate most. Pull from measured welding and fabrication runs, supplier data, and recent quotes rather than memory.
  • How should I act on the output? Use the gap to target to prioritize the next welding and fabrication kaizen or corrective action.
  • What should I double-check before acting? Confirm the counts came from the same time window and the same scope; mismatched scope is the most common error.
