Frame Weld Yield at 99% target weld first-pass yield: a worked example

This scenario runs the frame weld yield calculation on the strong side: 99% target weld first-pass yield, with every other input held at its documented default. a bicycle, e-bike, or scooter frame line needs to compare passed welded frames with total inspected weldments for a model, shift, or lot

The inputs for this scenario

  • Frames passing weld inspection: 468 frames (unchanged)
  • Total frame weldments inspected: 500 frames (unchanged)
  • Target weld first-pass yield: 99 % (raised for this scenario; the documented default is 96)

Working through the calculation

  • Applying the documented formula (Frame weld yield = accepted welded frames ÷ inspected frame weldments × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 93.6 % weld yield for frame weld yield, the number this scenario is built around.
  • At this operating point the engine returns 5.4 points for weld yield gap to target.
  • At this operating point the engine returns 468 frames for accepted welded frames.
  • At this operating point the engine returns 500 frames for inspected frame weldments.

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. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Frame weld yield: 93.6 % weld yield (headline result)
  • Weld yield gap to target: 5.4 points
  • Accepted welded frames: 468 frames
  • Inspected frame weldments: 500 frames
