Pipe Welding Estimating

Pipe Welding Bids
That Win the Job

Nobody wins a bid by lowballing. And nobody wins by overestimating and getting beat by the guy who guessed. IronKit gives you accurate pipe welding costs — so your bids are competitive and you don't leave money on the table.

Real weld costs, not approximations

Weld Cost Calculator pulls real cost-per-inch data for your process, your material, your crew. No more multiplying "it feels like 48 inches" by a guess.

📋

Build the whole bid in one place

Quote Writer + Weld Cost Calculator together means you build the full bid — materials, labor, consumables, overhead — without switching between spreadsheets.

Turnaround time that keeps you in the game

Pipe jobs have tight bid windows. IronKit generates complete bids in under 15 minutes, so you can respond to last-minute RFIs and still make dinner.

The workflow

Two tools, one bid: Quote Writer + Weld Cost Calculator

Most pipe welding bids fail at the weld cost step — the estimator guesses a labor multiplier and hopes the job pencils out. IronKit replaces the guess with actual geometry-based math.

Step 1 — Weld Cost Calculator

Enter your pipe size, wall thickness, weld type, and process. IronKit calculates the true cost per inch including:

  • Consumables — electrode weight, shielding gas, backing gas
  • Labor time per joint based on weld type and position
  • Root pass, fill, and cap hours broken out
  • Schedule 10 through XXS, or manual wall thickness entry

Step 2 — Quote Writer

Takes the Weld Cost Calculator output and builds a complete bid package:

  • Line-item material list — pipe, fittings, flanges
  • Per-joint weld costs scaled to your quantity
  • Labor summary by process
  • Overhead and markup applied
  • Professional PDF export, ready to send
When to use both together: You have a pipe job with multiple joint configurations — socket welds on branches, butt welds on straight runs, and flanged connections. Calculate each type in Weld Cost Calc, pull into Quote Writer, export the bid. One workflow, no Excel required.
Common questions

Pipe welding bid questions, answered

Does IronKit handle different pipe schedules and wall thicknesses?

Yes. Weld Cost Calculator includes dropdowns for Schedule 10 through XXS, with manual entry for non-standard wall thicknesses. Cost-per-inch updates automatically based on your input.

What's the difference between socket weld and butt weld in the calculator?

Socket weld and butt weld have different joint geometries and therefore different labor times. IronKit's Weld Cost Calculator handles both: socket welds (typically used for small-diameter piping up to 2" NPS) and butt welds (standard for larger pipe and higher-pressure applications). Each weld type has its own labor hour calculation.

Can I include field welding versus shop welding in the same bid?

Yes. Quote Writer lets you split labor into shop rate and field rate, so bids that include both shop fabrication and site installation reflect the actual cost difference.

What pipe codes does IronKit support?

IronKit supports WPS generation for AWS D1.1 (structural), ASME Section IX (pressure), and API 1104 (pipeline). The Weld Cost Calculator is process-agnostic — it calculates weld costs based on your inputs regardless of which code applies to the job.
