Welding & Sheet Metal Toolkit
Weld & Sheet Metal Calc Suite
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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.
