what books do i need for cwi test 1

[myfastcar]

im taking the cwi test in april 09 and was wondering if i need any other books other than welding of pipeline and related factlities 20th edition and and are there any parts i need to focus more on thanks alot

I would recommend the "Welding Inspector's Handbook" available from AWS.

If you take the AWS seminar, you will be given a stack of books to study.

If you don't take the seminar, buy the following:

Welding Inspection Technology and Workbook
AWS A2.4 Welding and NDT Symbols
AWS A3.0 Terms and Definitions

You will have to know how to use a micrometer and dial caliper

Calculate cross sectional area of a round and rectangular piece.
Calculate ultimate tensile strength, elongation, and reduction in area using both US customary units as well as metric conversions.
The hard part will be to identify various weld discontinuities using plastic weld replicas and measure weld sizes, undercut, etc.

You will be provided with a "welding standard" that is a compilation of AWS D1.1, ASME Section IX, and a little API thrown in for good measure. The trick is to read the specification without allowing your day to day experience influence your decision on accepting or rejecting welds. Use only the criteria listed in the specification.

Good luck, and you will if you study the material well in advance of the examination.

Best regards - Al

AWS has a publication specifically written to prepare candidates for the CWI exam, titled 'Certification Manual for Welding Inspectors' CM-2000. The suggestions from GTAW are all valid but if I could only have one, this would be it.

The AWS seminar is definitely worth it. And then the one week class AWS gives right before the test is excellent.

I just went through the whole thing. I tested December 12th, and got my grades back the 27th.

There are three tests involved, and they have to be completed in 2 hours each. The first part is General Knowledge and is 150 questions closed book. (Part A)

The second part is Part B, the practical test. Part B is the compiled welding standard GTAW mentions. This is where most people who miss the test mess up. Part of the reason is the samples are pretty beat up and may confuse people. With the proper preparation it'll go well. Another part is if you have lots of experience in inspecting, it may well work against you. As GTAW mentions, accept or reject based on the supplied criteria only. Some of the porosity is unbelievably huge, but depending on the criteria is acceptable.

Part C is your Code section. I tested with API 1104 and it sounds like you will be also. Both Part B and Part C are open book, so memorization of formulae won't be an issue.

I understand it used to be harder, with much more math. The one week immediately preceeding the tests is invaluable. They really drum it into your head.

There are a lot of welding symbols questions, maybe 16. So know those cold. Lots of questions on welding processed, too.

To pass, you'll need to get 72 on each test.

Go to the AWS site, they have downloadable versions of Part B, and other aids.

Hope this helps, and good luck with your test!

IM signed up to take cwi seminarat the hobart site in oh. I've been putting this off for the last ten years an now my GI Bill is about to expire. So its now or never. I've been a welder for 15yrs mainly nuclear. The inspection terms an def. are not a problem but the math has always held me back. Any pointers? How many people pass on there first attempt?

Don't let the math intimidate you. The most significant math you'll run into is computing throat depth and areas of fillet welds...requiring a little geometry or trigonometry. Learn some basic right triangle relationships (sine, cosine, hypotenuse, area, etc.)

Good luck.
