Welding Reference Pro vs Welding Sheet Metal Calculator

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. FREE FEATURES: 6 calculators (Weld Settings, Wire Feed Speed, Gas Flow, Filler Weight, Unit Converter, Weld Cost), all 9 reference guides, Training Academy study modules, qualification tracker, checklists, weld log (up to 15 entries). PRO UNLOCK ($9.99 one-time): Heat Input Calculator, Preheat Calculator, CWI Exam Prep, AWS D1.1 Exam Prep, ASME IX Exam Prep, OSHA Safety Exam Prep, Welding Math practice, WPS Reference templates, Distortion Guide, unlimited weld log entries.

Welding & Sheet Metal Toolkit is a professional calculator suite built for welders, fabricators, sheet-metal shop owners, weld inspectors, and CNC machinists. Everything runs fully offline, so you can price a weld, size a blank, or check heat input right on the shop floor without cell service or Wi-Fi. Stop juggling scraps of paper, dusty handbooks, and half-broken spreadsheets. Get 11 focused tools in one clean app, built around real AWS and ASME workflows. WHAT'S INCLUDED: Welding - Weld Cost Estimator (FREE): Price any joint by wire, gas, labor, and deposition rate. - Weld Parameters Guide: Recommended amps, volts, wire feed speed, polarity, and shielding gas for SMAW, GMAW (MIG), FCAW, and TIG across common thicknesses. - Welding Heat Input: Calculate heat input in kJ/in or kJ/mm for procedure qualification and WPS records. Sheet Metal & Forming - Bend Allowance: K-factor based bend allowance, bend deduction, and setback for press brake work. - Flat Pattern Development: Develop accurate flat blanks from finished part dimensions. - Stamping Tonnage: Estimate press tonnage for blanking and piercing from perimeter, thickness, and shear strength. Surface Treatment - Dry Film Thickness: Convert wet film to DFT and plan coating coverage and consumption. - Sandblast Rate & Cost: Estimate blast time, grit use, and cost per square foot by profile and nozzle size. Mechanical & Fiber - CNC Thread Drill Hole (FREE): Tap drill sizes and thread chart reference for machinists. - Pulley Belt Length: Calculate belt length for two-pulley drive systems. - Fiber Splice Time (FREE): Estimate fusion splice time for fiber optic jobs. WHO IS IT FOR: - Welders running SMAW / stick, MIG, and TIG in the field or shop - Fabricators and sheet-metal shop owners quoting jobs - Weld inspectors checking heat input and procedure compliance - CNC machinists and tool room techs - Manufacturing and welding engineers writing WPS and PQR WHY WELDERS & FABRICATORS LOVE IT: - Fully offline. Works in bays, basements, and job sites with zero signal. - No ads, no tracking, no subscription traps. - One-time unlock. Buy it once, use it for years. - AWS and ASME aware formulas for heat input, bend allowance, and tonnage. - Professional accuracy with clean, fast input forms designed for gloves and bright sunlight. ONE-TIME UNLOCK: Unlock All Calculators is a single $12.99 USD non-consumable in-app purchase. It unlocks all 8 Pro calculators plus reference tables, forever, on your Apple ID. No recurring fees. Price a weld, develop a flat pattern, and log heat input from the same app, all before the next bend cycle finishes.
