Welding — Butt Weld (Single-V)
Weld metal, arc time and duration for butt weld (single-v) at a stated deposition rate.
A single-V butt's volume is the gap plus the triangle — bevel angle and root opening drive consumption more than thickness alone. Fit-up discipline is weld-wire economics in disguise.
Formula
Note: Erection-planning estimate only. Member weights, connection capacities and tolerances for execution must come from the issued drawings, the EOR and the erection engineer — never from a generic calculator.

About Welding — Butt Weld (Single-V)
Welding — Butt Weld (Single-V) computes the governing relationship A ≈ 0.8t² + 3t (60° V, 3 mm root) · m = A·L·ρ×1.1 live as you type. A single-V butt's volume is the gap plus the triangle — bevel angle and root opening drive consumption more than thickness alone. Fit-up discipline is weld-wire economics in disguise. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Welding — Butt Weld (Single-V)
- 1Enter your values — Plate thickness, Total weld length, Deposition rate, Operator factor (sensible defaults are pre-filled).
- 2Read the live results: Weld metal, Welder-hours.
- 3Check the "with your numbers" line to see A ≈ 0.8t² + 3t (60° V, 3 mm root) · m = A·L·ρ×1.1 substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Welding — Butt Weld (Single-V)?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula A ≈ 0.8t² + 3t (60° V, 3 mm root) · m = A·L·ρ×1.1 with authoritative sources cited on the page (AWS D1.1 — Structural Welding Code (Steel))
- ✓A single-V butt's volume is the gap plus the triangle — bevel angle and root opening drive consumption more than thickness alone.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the welding — butt weld (single-v) use?+
It evaluates A ≈ 0.8t² + 3t (60° V, 3 mm root) · m = A·L·ρ×1.1, exactly as published. Sources: AWS D1.1 — Structural Welding Code (Steel). The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
A single-V butt's volume is the gap plus the triangle — bevel angle and root opening drive consumption more than thickness alone. Erection-planning estimate only. Member weights, connection capacities and tolerances for execution must come from the issued drawings, the EOR and the erection engineer — never from a generic calculator.
When is this calculator the right tool for the job?+
Weld metal, arc time and duration for butt weld (single-v) at a stated deposition rate. A free structural steel delivery & erection tool. Fit-up discipline is weld-wire economics in disguise. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
