Welding Cost Calculator — Arc Time, Labor & Consumables

Who this is for: For fabrication shops and mobile welders quoting by the job — especially the ones who quote by feel and discover the truth at invoice time.

Weld length, travel speed and shop rate in — get arc time, labor, consumables and the price for the run.

Quick answer: Welding price = (length ÷ travel speed) arc time × shop rate + setup + consumables. A 60-inch MIG run at 18 IPM = 3.3 arc-min; +20 min setup at $60/h = $23.30 labor + $7.20 filler/gas ≈ $30.53. Quote finishing separately. The calculator splits every line.

Fitting real assemblies takes 2–5× the arc time — and finishing (grind/paint) is $15–40/h more. Quote both as separate lines so customers can choose "as-welded" and save honestly.
Arc time = length ÷ travel speed. Manual MIG 15–25 IPM · TIG 5–12 · position work −30–50%. Welder rates $45–85/h shop, $75–150 mobile. Consumables: MIG ≈ $0.07–0.20/in, TIG SS $0.30+/in.

StatusQuotes use standard shop math: machine-hour rate × cycle time + materials + setup amortization. SFM/chipload figures are conservative HSS starting points (carbide runs 3–4× SFM). Compiled September 2026 — estimates for budgeting; real quotes come from the shop that runs the job.

How do you price welding work?

Arc time drives it: weld length ÷ travel speed = minutes under the arc. Manual MIG on carbon steel travels 15–25 IPM on typical joints; TIG runs slower (5–12 IPM). Arc time ÷ 60 × shop rate ($45–85/h for welders) is the labor line; filler wire and shielding gas add $0.07–0.30 per inch depending on joint and process; setup (fitting, clamping, positioning) is charged like any machining setup. Example: a 60-inch run at 18 IPM = 3.3 arc minutes + 20 min setup at $60/h = $23.30 labor + $7.20 consumables ≈ $30.53 — and that's before grinding, inspection and the markup that keeps the lights on.

Common uses

  • Quoting bracket and frame welds by the run
  • Comparing MIG vs TIG cost on the same joint
  • Checking a mobile-welding minimum call against real time
  • Teaching apprentices why 'it's just a quick bead' isn't

Frequently Asked Questions

How do welders charge for jobs?
US fabrication shops: $45–85/hour for welding labor, often with a one-hour minimum; mobile welding $75–150/call. Job quotes combine arc time, setup, consumables and finishing — the calculator breaks each out so the customer sees why.
What travel speed should I assume?
Manual MIG carbon steel: 15–25 IPM on fillets; TIG: 5–12 IPM depending on amperage and finish requirements; machine (tractor) work: 30+ IPM. Thin material and overhead positions slow everything — quote the worst position, not the bench.
How much do filler and gas cost per inch?
MIG carbon steel: ~$0.05–0.12/in of wire plus $0.02–0.08/in of gas — call it $0.07–0.20 all-in. TIG on stainless with back-purging can run $0.30+/inch. The calculator takes both as inputs so exotic alloys price honestly.
Why is setup such a big share?
Fitting, clamping, tacking and repositioning often take 2–5× the arc time on real assemblies. A 'one quick bead' on a fixture-less part is 30 minutes of wrangling and 2 minutes of welding. Quote setup separately and the disputes disappear.
Should finishing (grinding, paint) be in the weld quote?
Only if you're doing it. Quote weld, grind and finish as separate lines — customers who waive finishing pay less, and you stop eating abrasives and hours invisibly.
