Frame Weld Yield at 69% target weld first-pass yield: a worked example

This worked example runs the frame weld yield numbers for a tougher week than the baseline: 69% target weld first-pass yield instead of the typical 96%. Calculate accepted bicycle, e-bike, or scooter frame welds against inspected frame weldments, with a target yield for fabrication quality review.

The inputs for this scenario

  • Frames passing weld inspection: 468 frames (held at the documented default)
  • Total frame weldments inspected: 500 frames (held at the documented default)
  • Target weld first-pass yield: 69 % (the input this scenario stresses; the baseline uses 96)

Working through the calculation

  • The calculation starts from the formula this tool documents: Frame weld yield = accepted welded frames ÷ inspected frame weldments × 100.
  • Frame weld yield works out to 93.6 % weld yield at these inputs, and this is the headline figure for the scenario.
  • Weld yield gap to target works out to -24.6 points at these inputs.
  • Accepted welded frames works out to 468 frames at these inputs.
  • Inspected frame weldments works out to 500 frames at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target weld first-pass yield sits at 96% and the headline result is 93.6 % weld yield, this scenario lands almost exactly on the baseline at 93.6 % weld yield.
  • Use it for daily or per-batch line monitoring, after a fixture or weld-program change, or when qualifying a new frame model or welder. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Frame weld yield: 93.6 % weld yield (headline result)
  • Weld yield gap to target: -24.6 points
  • Accepted welded frames: 468 frames
  • Inspected frame weldments: 500 frames
