Pressure Vessel Weld Cost at 92% weld scope included: a worked example

Push weld scope included up to 92% and the picture changes. This example computes every intermediate figure at that operating point. Use it when quoting a pressure vessel or reviewing a weld-heavy fabrication package and you need a weld cost you can defend to the customer.

The inputs for this scenario

  • Total weld length: 100 in (unchanged)
  • Welding cost per inch: 45 $ / in (unchanged)
  • Weld scope included: 92 % (raised for this scenario; the documented default is 80)
  • Fixed setup and NDE cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable weld cost = total weld length × welding cost per inch × weld scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for total pressure vessel weld cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for weld cost per inch of weld.
  • At this operating point the engine returns 4,140 $ for variable weld cost.
  • At this operating point the engine returns 250 $ for fixed setup and nde cost.

How this compares with the baseline

  • Against the tool's baseline example, where weld scope included sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • It computes total pressure vessel weld cost by multiplying weld length, cost per inch, and the scope included, then adding fixed setup and NDE cost, and returns cost per inch of weld. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Total pressure vessel weld cost: 4,390 $ (headline result)
  • Weld cost per inch of weld: 43.9 $ / piece
  • Variable weld cost: 4,140 $
  • Fixed setup and NDE cost: 250 $
