Welding Reference Pro

Welding Reference Pro puts every tool a welder needs in one app — calculators, reference guides, training, and QA checklists. No internet required. No subscription. One price, everything unlocked.

CALCULATORS (8)
Weld Settings — enter your process, material, and thickness to get amperage, voltage, wire speed, and electrode recommendations for MIG, TIG, Stick, and Flux-Core.

Wire Feed Speed — convert between wire feed speed and deposition rate across 6 wire diameters.

Gas Flow — get shielding gas type and flow rate recommendations by process, material, joint type, and position.

Filler Weight Estimator — calculate pounds of filler metal needed for 5 joint types with waste factors.

Unit Converter — 7 categories including length, temperature, pressure, flow rate, weight, heat input, and area.

Weld Cost Estimator — estimate labor, filler, and gas costs with your own custom rates. Edit every rate in the app.

Heat Input (Pro) — calculate joules per inch with process efficiency factors for SMAW, GMAW, GTAW, FCAW, and SAW.

Preheat Calculator (Pro) — input your carbon equivalent elements and thickness to get preheat temperature and crack sensitivity assessment.

REFERENCE GUIDES (9)
27 electrodes and filler metals — E6010 through Inconel, searchable by classification, type, or application. Electrode Guide, Welding Symbol Decoder (18 AWS A2.4 symbols), Joint Preparation Guide (13 joints), Weld Defect ID (10 defects with causes and fixes), Gas Reference Chart, Material Properties (18 materials including duplex and nickel alloys), NDE Methods, Heat Treatment Reference, and Pipe Welding schedules.

TRAINING ACADEMY
6 study modules with spaced repetition: Welding Fundamentals, Electrode Mastery, Blueprint Reading, Metallurgy, Weld Quality, and Code Awareness. Questions you get wrong come back sooner. Track your streak and progress.

EXAM PREP (Pro)
Practice for CWI (56 questions), AWS D1.1 (85 questions), ASME Section IX (88 questions), OSHA Welding Safety (56 questions), and Welding Math (45 questions). Timed mode, score history, and category filtering.

ENTERPRISE FEATURES
Qualification Tracker — track your welding certifications, positions, and expiration dates. Get warned when a cert is expiring.

QA Checklists — pre-weld, during-weld, and post-weld inspection checklists with standard templates. Tag by project.

Weld Log — attach a photo from your library, tag welding parameters, and save locally. Export to CSV or PDF for QA documentation.

Global Search — type "7018" and find the electrode, compatible settings, and defect fixes all at once.

Tap any result to copy it to clipboard. Save and name any calculation. Export results as PDF.
