Welding & Sheet Metal Toolkit

Heat input to flat patterns in seconds. Pro welding and sheet metal calculators, fully offline on the shop floor. No ads, no subscription.

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, and travel speed for SMAW, GMAW (MIG), 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, piercing, and forming.

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 $19.99 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. Download Welding & Sheet Metal Toolkit and put a real fabrication toolbox in your pocket.
