Description
If you run heat input calculations in the field, you already know the problem. Online calculators are rough. Excel sheets break. Doing it by hand mid-inspection wastes time you don't have. G3 is the first purpose-built heat input calculator for welding and QC inspectors. Enter your voltage, amperage, and distance. Hit start on the built-in arc timer when the arc strikes. Live readout as you weld — see your heat input building in real time. Stop it when the pass is done. Heat input and travel speed calculate instantly — in kJ/mm or kJ/in, your call. Built by a working inspector. Designed for real field conditions.
BUILT FOR • CWB certified inspectors (Canada) • CWI certified inspectors (USA) • CSWIP certified inspectors (International) • API 510, 570, 653, and 1169 • Oil and gas, pipeline, and pressure vessel inspection • Structural fabrication and shipyard QC
WHAT IT DOES • Built-in arc timer — tap start when the arc strikes, stop when the pass ends • Instant heat input and travel speed calculation • Selectable weld passes: Root, Hot Pass, Fill, Cap — track the entire weld in one place • Imperial and metric (kJ/mm and kJ/in) • Fully offline — works on the job site, in the field, underground • No login. No account. Free.
WHAT'S COMING G3 is the first module in a full QC documentation platform for inspectors — welder profiles, job history, PDF reports, Bluetooth gauge integration, and credential-specific documentation. Free for the core calculator, always.
What inspectors are saying: "Best heat input calculator ever. After using a number of heat input calculators in the field, I stumbled across G3. What a blessing in the field, usable offline, able to add welders for future projects, the ability to speak to the developers to make suggestions. It's the all-in-one tool needed for the inspection realm." — 5 stars, App Store, Canada

This app came in very handy for me. Setting my welding/heat parameters with ease. Shout out to the developer for making my job a breeze!

I'm very disappointed with the G3 Inspection Tools app. As an experienced professional, I found the app to be a complete waste of time and effort. The core functionality of the app, which is supposed to help with code compliance and documentation, simply does not work correctly. The calculations are inaccurate, making it unreliable for field use. The user interface is also overly complex, with too many dropdown menus that don't seem to function properly. I would never recommend it to anyone
