Read full descriptionHide full description
Background ASME Sec II-D give the material stress, physical and mechanical properties table. There are some tools available for Table 1-A stress values determination at given temperature but no tool available for other tables for quick determination of properties at given temperature. Applicable Code / Edition & Standards This app is based on ASME Section II-D 2021 Edition for metric and US customary unit. Utility This app gives material properties at given temperature for different Code section, also help user to do the hand calculation using the values where no commercial design software is available in the market. Competitive Edge There is no app available in the market to cover most of the tables available in ASME II-D for material properties. This app fills that gap and facilitate user to use these values in hand calculation where no commercial software is available for particular Code section. Target Audience This app targets inspection agencies, pressure items manufacturing organizations, quality control personnel, Engineers and designers who are involved in pressure items design calculations. Non Consumable Subscription: You can download the app from App Store for free, however One time Non-Consumable subscription in-app-purchase is required before you can use any of the Tables of this app. Purchase can be made by going to the menu of the application. Terms and condition are also provided there.

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.

Verdict
The clearest difference is device support: StressTable2021 at 4 against Welding Reference Pro's 1. StressTable2021 also leads on iOS requirement (13.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.
