The Problem Isn't You. It's How It Was Explained.

You're looking at a weld symbol on a print. There's a reference line, an arrow, a fillet triangle, a number on each side, a flag and a tail with letters in it. You've welded that joint a hundred times. On the exam, with the clock running, arrow side and other side can still flip on you.

The fundamentals book explains the symbol in paragraphs: where the dimensions go, what sits above the line, what belongs in the tail. Six elements described in words, and not one of them drawn where it belongs.

Reference line, arrow, weld symbol, dimensions, supplementary symbols and tail: one drawing, every element labeled.

In this book, that symbol is one page. One drawing, with every element labeled in its fixed place: reference line, arrow, weld symbol, dimensions, supplementary symbols and tail. You see where each piece sits before you read a word about it.

The rest of the book works the same way. Arrow side vs. other side, porosity in four patterns, the fillet gauge on a concave weld, E7018 decoded, the D1.1 clause map: each one gets its own page.

So when a symbol shows up on Part A or on a shop print, you read it element by element, in the same order, without going back to the book.

Same Topic, Two Ways to Study It

THIS
  • The textbook: line after line
  • Joint types explained only in words
  • You walk into the exam still unsure
The configuration of the members to be joined determines the joint type, of which five basic forms are recognized. A butt joint is formed between two members lying approximately in the same plane. A corner joint is formed between two members located approximately at right angles in the form of an L. A T-joint is formed between two members located approximately at right angles in the form of a T, and may receive either a fillet weld or a groove weld. Lap and edge joints complete the classification.
FOR THIS
  • Each joint type in one drawing
  • The key rules in a box
  • You see it and you get it
Butt, corner, T, lap and edge: a T-joint can take a fillet or a groove weld.

One Page, One Topic, All Clear

Think of it this way:

Part B is underway. There's a fillet weld sample on the table, the gauge is in your hand, and the bead is concave.

In the book, the fillet gauge page shows both cases drawn: how the tool sits on a convex weld and how it sits on a concave one. On a concave fillet, you gauge the throat.

1/8 to 1/64 in, counted line by line: 5/16 in = 0.3125 in

The same goes for the V-WAC, the bridge cam, the Hi-Lo, the dial caliper and the steel rule: each one on its own page, drawn the way you hold it.

Welding Inspector Exam Illustrated is 67 illustrated pages in 8 parts, one topic per page, and it ends with a final review: the mix-ups that cost points, a one-page symbol routine and an exam-week checklist.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is it for me if I've been welding for years and now want to inspect?

Yes. It isn't a welding course: it covers what the inspector exam asks, from symbols and discontinuities to gauges and the code book. It also works if you come from QA/QC and have never welded.

Where does the content come from?

From AWS QC1 and the AWS publications in the CWI Body of Knowledge: A2.4, A3.0, B1.10, B1.11 and D1.1/D1.1M. Every page is checked against them. The D1.1 map uses the current clause numbering: Clause 5 prequalification, 6 qualification, 7 fabrication, 8 inspection. If your code book shows the same numbers, the map matches it. The book doesn't reproduce the code text, so for Part C you still need your own code book, in the edition your exam uses.

Is this official AWS material?

No. It's independent study material, not affiliated with or endorsed by the American Welding Society. It doesn't give you a certificate or credit hours: the CWI certification comes only from AWS, after you pass the exam.

Does it replace a CWI seminar or course?

No. It's for studying and reviewing alongside your seminar, your course or the official publications. For Part B it shows how each gauge sits and how to read it, drawn the way you hold it. You still practice with real gauges and weld samples.

Are the practice questions the real exam questions?

No. They're written for this book, in the style of Part A and Part C, and each one comes with the answer explained.

When and how do I get it?

The book and the 2 bonus books arrive as PDFs by email, at the address you enter at checkout.

Do I have to pay every month?

No. It's a one-time payment.

Can I have it on paper?

Yes. It's a PDF you can print at home or at a print shop and keep at the shop.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.
