Field notes
The page groups its catalogue into tuyauterie, soudure, chaudronnerie, and usinage, with entries ranging from pipe cut lengths and sheet-metal developments to weld heat input and tolerance tables. It says results include the formula, a numerical application, and a cited source; the landing page also lists French, English, German, Spanish, and Portuguese. Android and iOS are described as forthcoming, so the supplied evidence does not establish current app access.
