Full Feature List
8 calculators, 8 reference guides, saved history, and imperial/metric toggle — built for the shop floor, not a classroom.
Calculators
Stop cross-referencing charts. Enter your variables, get your answer.
MIG, TIG, Stick, and Flux-Core × 4 materials × any thickness. Returns amps, volts, wire speed, electrode, gas type, and polarity in one tap.
Amps × volts × 60 ÷ travel speed with 5 process efficiency factors (SMAW, GMAW, GTAW, SAW, FCAW). Output in kJ/in and kJ/mm.
Full Carbon Equivalent (CE) formula across 7 alloying elements. Returns required preheat temperature, crack sensitivity index, and PWHT recommendation.
Convert wire feed speed ↔ deposition rate across 6 wire diameters and 3 material densities (steel, stainless, aluminum).
Select process, base material, joint type, and position — returns the correct shielding gas and flow rate in CFH and L/min.
Estimate filler metal needed across 5 joint types with configurable waste factors and spool count calculation.
7 categories: length, temperature, pressure, flow rate, weight, heat input, and area. Full imperial ↔ metric conversion.
Complete cost breakdown: labor, filler metal, shielding gas, and overhead per process. Know your per-foot cost before starting the job.
Reference Guides
No internet required. Every spec, symbol, and standard is baked into the app.
27 electrodes and fillers across Stick, MIG, TIG, Flux-Core, and Nickel. Searchable. Each entry includes coating, polarity, positions, and applications.
18 AWS A2.4 welding symbols across 5 categories. Tap any symbol for a full breakdown — what it means, how to read it on a print.
13 joint types across 5 categories (butt, corner, T, lap, edge) with bevel angles, root gaps, and land dimensions.
10 common defects with severity rating (High/Medium/Low), root causes, and corrective actions. Porosity, undercut, cracking, incomplete fusion, and more.
Save any calculation result for quick recall. Powered by SwiftData — stays on device, no account needed.
Global unit toggle — flip between imperial and metric once and every calculator updates automatically.
Designed for low-light shop conditions. High-contrast orange accent on a near-black background — readable without blinding you at night.
Every calculator, every guide, every reference — all work without a network connection. No subscription, no sync, no cloud dependency.
Pro Upgrade
The core app is free. Pro removes limits and unlocks advanced calculator features.
Full access to every calculator with no usage limits.
