How do you calculate fabricated frame yield?

Divide accepted frames by total frames built and multiply by 100. With 188 accepted out of 205 built, yield is 91.71%. Subtracting that from a 96% target gives a 4.29 percentage-point gap.

What is a good first-pass frame yield?

World-class weld fabrication runs 95-98% first-pass on stable fixtures; 90-94% is workable but signals rework drag. The example's 91.71% sits below the 96% target, flagging a real quality gap worth a root-cause look.

What's the difference between yield and the yield gap?

Yield is the actual pass rate (91.71%). The gap is yield minus target, in percentage points (4.29 pts short of 96%). The gap tells you how far improvement work has to travel.

Why use percentage points instead of percent for the gap?

Comparing two percentages is clearer in points: being 4.29 points below target is unambiguous, whereas saying yield is '4.5% lower' invites confusion about whether it's relative or absolute. Points keep quality-board reporting consistent.

Does first-pass yield count reworked frames as accepted?

No. First-pass yield only credits frames that pass without rework. A re-welded frame that later passes is still a first-pass failure here — that's the point, because rework is the cost you're trying to surface.

How many frames should I sample before trusting the yield?

With only a handful of frames, one reject swings the number wildly. The 205-frame batch in the example gives a stable read; for low-volume frames, roll several batches together before reacting to a gap.

Agricultural Equipment & Farm Machinery Manufacturing calculator

Fabricated Frame Yield Calculator

Fabricated Frame Yield measures the share of welded and fabricated ag-equipment frames that pass inspection on the first pass, then shows how far that sits from your target. Weld-shop supervisors and quality engineers at farm-machinery plants track it to catch fixture drift, weld-parameter problems, and material issues before they cascade into the assembly line. Frame rework is expensive — re-welds, grinding, re-coating — so a yield slip of a few points can quietly consume a shift's worth of touch labor. This calculator turns raw accept/build counts into a clean first-pass yield and a percentage-point gap you can put on a daily quality board.

What this calculator does

Calculate first-pass yield for fabricated farm machinery frames from accepted frames, total frames built, and a yield target.
a fabrication or quality manager needs to measure first-pass quality for welded farm machinery frames
It computes first-pass fabricated-frame yield as accepted frames divided by total frames built, then reports the gap in percentage points to your target.

Formula used

Fabricated frame yield = accepted fabricated frames ÷ total fabricated frames built × 100
Frame yield gap = fabricated frame yield - target first-pass frame yield

Inputs explained

Accepted fabricated frames:
Total fabricated frames built:
Target first-pass frame yield:

How to use the result

Use it on a daily or per-batch basis to monitor weld-shop quality and flag when frame yield drifts below target.
It treats every rejected frame equally, so a batch of minor cosmetic rejects and a batch of scrap-grade structural failures produce the same yield number despite very different cost.

Current U.S. benchmarks

Industrial natural gas averages $4.9 per Mcf (EIA, Apr 2026), down 7.7% from a year earlier, with industrial electricity at 8.66 cents per kWh. Process heating and refrigeration budgets track both.
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
The U.S. has 21,668 machinery manufacturing establishments employing about 1,086,146 workers (Census County Business Patterns, 2023).
