About Gauge: Welding Inspector Prep
Preparation for all three parts of the AWS Certified Welding Inspector examination — Fundamentals, Practical and Code Application — built for the way the exam is actually scored. PART A IS FREE. ALL OF IT. Not a sampler and not a trial. Every Part A lesson, every Part A question, and the full-length 150-question timed form, free, with no account and no network. Part A is the longest of the three sittings and the one candidates lose most often. You can find out whether this app is any good before you are asked for money. 72 PERCENT, THREE TIMES, PLUS THE COMPOSITE The CWI is not one exam. It is three separately-scored parts, and you need 72% on each one and a 72% composite across all three. A strong Part A does not carry a weak Part C. Every practice form here scores the way the real one does, so you find out which part is going to fail you while there is still time to fix it. PART C: PRACTISE NAVIGATING A CODE, NOT MEMORISING ONE Part C is open book, and the skill it tests is finding the governing clause fast and applying it exactly. So this app ships GSWS-1, an original 319-clause welding specification written for it — with acceptance tables, qualification ranges, cross-references, and the exceptions that catch people who stop reading at the first clause they find. GSWS-1 is fictional, it says so on its own first page, and every value in it is invented. That is deliberate. The published codes are copyrighted and cannot be reproduced, and a candidate who has only ever memorised one code's numbers is helpless in front of a different one. Navigating an unfamiliar specification is the transferable skill, and it is the one Part C actually measures. Every Part C question quotes the clause it turns on, so the item is answerable on a phone with nothing else open. WORKED SOLUTIONS, NOT BARE ANSWERS Heat input, carbon equivalent, fillet leg and throat, deposition rate, radiographic geometric unsharpness, ultrasonic sound path and skip distance. Every calculation shows its steps with the units carried through, so when you get one wrong you can see which line you lost it on instead of guessing. THE CALCULATORS ARE FREE. FOREVER. Fifty-five of them. They stay free whether you buy anything or not, because an inspector runs these numbers on shift for a whole career and a reference tool you have to subscribe to is a reference tool you stop opening. ALSO INCLUDED Flashcards and scenario-based tasks. Spaced repetition that surfaces what you are actually forgetting. Progress tracking per subject area, bookmarks, and personal notes. Everything is on the device and works with no signal, because fab shops and site trailers are steel buildings. FREE, AND WHAT THE UNLOCK ADDS Free: the entire Part A — 24 lessons, its full 300-question bank and its timed form — plus all 55 calculators and a sample of Part B and Part C questions. The one-time unlock opens the Part B and Part C banks, their timed forms, the full GSWS-1 specification, spaced repetition across all three parts, and weak-area analytics. One payment, no subscription, no account. WHY THIS EXISTS The CWI seminar-and-exam package runs well over a thousand dollars, and a retake is not cheap either. This app is built for the candidate paying their own way, and for the retake as much as the first attempt.
