Representative welding shop scenario

المشكلة

A fab shop quotes labor and material but under-loads fit-up, rework, and gas consumables — visible margin erodes after callbacks.

مجموعة المدخلات

• Material cost, labor hours, labor rate
• Gas/consumables, fit-up hours, rework risk %
• Target margin

الخسارة الخفية

Fit-up, rework buffer, and consumables under-loaded in the headline weld quote.

Rework & fit-up buffer

نتيجة الحساب

Modeled loaded weld cost exceeds quick quote by an illustrative margin gap — see tool for threshold read.

Base weld cost loaded with hidden multipliers for fit-up, rework buffer, and volatility band; minimum safe price at target margin.

الإجراء المقترح

Compare quoted price to minimum safe floor before accepting the job.

الأثر المقدر: Modeled waste exposure if quoted below P90 cost band — illustrative range only.

ملاحظة المنهجية

Deterministic weld bid model with user rework risk — representative framing only.

• Flat labor rate; consumables as entered
• Rework risk percent drives tolerance multiplier
• Representative scenario — modeled exposure, not a verified customer outcome.
