Welding Reference Pro Full Feature List
Everything inside the app
8 calculators, 8 reference guides, saved history, and imperial/metric toggle — built for the shop floor, not a classroom.
Calculators
8 calculators that do the math for you
Stop cross-referencing charts. Enter your variables, get your answer.
Weld Settings Calculator
MIG, TIG, Stick, and Flux-Core × 4 materials × any thickness. Returns amps, volts, wire speed, electrode, gas type, and polarity in one tap.
Heat Input Calculator
Amps × volts × 60 ÷ travel speed with 5 process efficiency factors (SMAW, GMAW, GTAW, SAW, FCAW). Output in kJ/in and kJ/mm.
Preheat Calculator
Full Carbon Equivalent (CE) formula across 7 alloying elements. Returns required preheat temperature, crack sensitivity index, and PWHT recommendation.
Wire Feed Speed Converter
Convert wire feed speed ↔ deposition rate across 6 wire diameters and 3 material densities (steel, stainless, aluminum).
Gas Flow Calculator
Select process, base material, joint type, and position — returns the correct shielding gas and flow rate in CFH and L/min.
Filler Metal Weight Estimator
Estimate filler metal needed across 5 joint types with configurable waste factors and spool count calculation.
Unit Converter
7 categories: length, temperature, pressure, flow rate, weight, heat input, and area. Full imperial ↔ metric conversion.
Weld Cost Estimator
Complete cost breakdown: labor, filler metal, shielding gas, and overhead per process. Know your per-foot cost before starting the job.
Reference Guides
8 reference guides — offline, always
No internet required. Every spec, symbol, and standard is baked into the app.
Electrode / Filler Guide
27 electrodes and fillers across Stick, MIG, TIG, Flux-Core, and Nickel. Searchable. Each entry includes coating, polarity, positions, and applications.
Welding Symbol Decoder
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.
Joint Preparation Guide
13 joint types across 5 categories (butt, corner, T, lap, edge) with bevel angles, root gaps, and land dimensions.
Weld Defect Identification
10 common defects with severity rating (High/Medium/Low), root causes, and corrective actions. Porosity, undercut, cracking, incomplete fusion, and more.
Saved Calculations
Save any calculation result for quick recall. Powered by SwiftData — stays on device, no account needed.
Imperial / Metric Toggle
Global unit toggle — flip between imperial and metric once and every calculator updates automatically.
Dark Theme
Designed for low-light shop conditions. High-contrast orange accent on a near-black background — readable without blinding you at night.
