Calculators, simulators and study material published on app.simplendt.com.br. No signup, no login. Maintained as support for the welding and NDT technical community.
This page collects tools I built for SimpleNDT internal use and decided to keep open. Each one is anchored on an explicit normative reference — ASME Section IX, AWS A2.4, ASME Section V — and none requires signup. If you find an error or have a suggestion, write to contato@simplendt.com.br.
Each opens in a new tab on app.simplendt.com.br.
Qualified ranges QW-452 (thickness/diameter), QW-461 (positions), QW-423/QW-424 (P-Number) — for both welder and procedure. Includes set-cover optimization via QW-424.1: given a welding plan, returns the minimum set of PQRs that covers all joints.
Open · no loginIndependent angle UT detector simulator — navigation interface inspired by the Krautkrämer USM Go. Live A-scan, V1/V2 calibration, gain, range, reject and gate controls — with embedded test pieces. For SNT-TC-1A Level II/III practical prep. Not affiliated with Baker Hughes/Waygate; nominative trademark use only.
Open · no loginA set of three tools that work together for angle UT inspection planning: beam path computation (skip, half-skip, full-skip per angle and thickness), field ruler for angle probes, and joint template for visualizing coverage in the bevel.
Bridge Cam (Cambridge gauge) in digital form — bevel angle, fillet leg, effective throat, undercut and reinforcement height. Includes guided fillet measurement exercises.
Open · no loginVT exercises and theory for SNT-TC-1A Level 1 and 2 prep — weld discontinuities, visual acceptance criteria, lighting, auxiliary tools (templates, magnifiers, mirrors) and code references.
Open · no loginReading and constructing AWS A2.4 symbols — joint preparation, process, position, length, spacing, contour and finish. Interactive exercises to consolidate correct interpretation of arrow, reference line and tail.
