About this app

Engineering Buddy is a comprehensive toolkit designed for engineers, fabricators, technicians, and students working in mechanical and structural engineering.

TOOLS INCLUDED:

⚙ Weight Calculator
Calculate weight for 9 profiles — Flat Bar, Round Bar, Square Bar, Hexagonal Bar, Round Tube, Square Tube, Rectangular Tube, Angle, and Plate — across multiple materials including steel, aluminum, copper, brass, and more.

📐 Profile Calculator
Calculate cross-sectional area, moment of inertia, and section modulus for polygon bar stock profiles.

🔩 Thread Reference
Complete metric and imperial thread data — major diameter, minor diameter, pitch, tap drill sizes for coarse, fine, and non-standard threads.

📏 Unit Converter Pro
10 conversion categories — Length, Area, Volume, Mass, Temperature, Pressure, Force, Energy, Speed, and Hardness. Clean chip-based interface with instant results.

🔬 Material Reference DB
92 engineering materials including structural steels, stainless steels, alloy steels, tool steels, and cast irons. EN standard numbers, delivery conditions, yield strength, tensile strength, elongation, and hardness data.

🔧 Pipe Schedule DB
Full ASME B36.10 and B36.19 pipe data. Search by pipe size, OD, OD+ID, or wall thickness with tolerance filters.

⚡ Welding Electrodes
36 electrodes across SMAW, MIG-GMAW, TIG-GTAW, and FCAW processes. AWS digit-by-digit decode, amperage tables, base metals, applications, and ISO equivalents.

🔣 Welding Symbols
AWS A2.4 and ISO 2553 welding symbols reference. 24 symbols across 6 categories with placement rules, dimension guides, and AWS vs ISO comparison.

DESIGNED FOR THE FIELD
Dark engineering theme optimized for workshop and site use. All tools work fully offline — no internet connection required, no ads, no data collection.
