What this is
GaugePass has two layers on one domain. The reference layer — 40 weld symbol pages, 50 filler metals, 25 discontinuities, 15 math topics and 12 process and examination pages — is free, public and permanent. The practice layer is a question bank, a terminology deck, and the gauge trainer.
The split is deliberate and it is not a funnel trick. Reference pages are what people link to and search for, and gating them would make the site worse at the only job that matters on the open web. The paid part is the practice depth, because that is the part that takes real work to build and real work to use.
Where the content comes from
All of it was written for this site. The weld-symbol drawings are original SVG, constructed from the public factual conventions of the notation — that a fillet symbol is a right triangle with its perpendicular leg to the left, that information below the reference line describes the arrow side, that the size sits left of the symbol and the length-pitch to the right. Facts about a notation are not anybody's property; the figures that express them are, so none of these were traced, measured or adapted from any published document.
Every practice question is original, authored from general textbook-level welding knowledge. None comes from a published question bank, seminar handout, or examination.
The welding math pages are checked by the test suite: every worked example's arithmetic is verified against the calculator implementation, so a transcription slip breaks the build instead of quietly teaching you the wrong number.
What this site does not do
It does not reproduce any welding code or specification — no clause text, no tables, no figures, no acceptance criteria. Discontinuity pages explain how inspectors reason about a flaw, never what any particular code will accept. The numbers that decide accept or reject come from the document governing your job, and that document is the one you should be reading on the job.
It also does not test code navigation. A question whose answer is “look it up in table such-and-such” teaches you to memorise a number that will be different on your next contract.
