Helps prepare you for the CWI/CWE Exam (Part B) This workshop provides hands-on training in the use of weld measurement tools and plastic weld replicas to determine the sizes of various weld discontinuities. Students will compare what they find to the criteria in a sample codebook to determine the acceptability or rejection criteria of the sample weldments. The workshop also includes a sample practical examination to prepare test candidates for Part B (Practical Applications) of the CWI examination. By attending this workshop, you can learn: Use of inspection tools. How to ensure compliance with the applicable code. Dos and don’ts of documentation. When a discontinuity is acceptable. When a discontinuity can be rejected. Why visual inspection can be the most effective NDE technique.

API 1104 Code Clinic ( 1.5 DAY)

Helps prepare you for the CWI Exam (Part C) if you are testing to API 1104 This four-hour course covers general provisions of API 1104, including qualification of welding procedures for welds containing filler-metal additions, design and preparation of the joint for production welding, nondestructive testing and acceptance standards, and automatic welding with and without filler-metal additions. Candidates will be given the Course material for training before the workshop and are supposed to come with a thorough reading in the class.

What Books Recommended to Study for CWI Test?

What Books Do I Need to Study for CWI Test? 

I would suggest the "Welding Inspector's Handbook" available from American Welding Society AWS. If you take the American Welding Society Certified Welding Inspector Training seminar, you will be given a stack of books to study.

If you don't take the CWI Training seminar, Buy the following books:

  • Welding Inspection Technology and Workbook
  • AWS A2.4 Welding and NDT Symbols
  • AWS A3.0 Terms and Definitions
To pass the CWI Exam, you will need to get 72% marks from Each Part.
Go to the AWS American Welding Society website, they have downloadable versions of Part B, and other aids.  Click Here to Downloads Free AWS CWI Books from American Welding Society online bookstore
There is lots of welding symbols questions, maybe 16. So know those cold. Lots of questions on welding processed, too.
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.
I understand it used to be harder, with much more math. The one week immediately preceding the tests is invaluable. They really drum it into your head.
The AWS CWI Training Seminar is definitely worth it. And then the one week class AWS CWI gives right before the test is excellent.
There are three parts of tests involved, and they have to be completed in 2 hours each part. The first part is (Part A) General Knowledge and is 150 questions closed book.
The second part is Part B, The Part B is practical test. Part B is the accumulate welding standard GTAW referral. This is where most candidates who miss the test mess up. Part of the reason is the samples are pretty beat up and may confuse candidates. With the good preparation it will go well. Another part is if you have so many years of experience in inspecting, it may well work against you. As GTAW mentions, accept or reject based on the supplied test only. Some of the porosity is unbelievably huge, but depending on the criteria is acceptable.
The third is Part C, The Part C is your Code section. I tested with API 1104 (Welding of Pipelines and Related Facilities) and it sounds like you will be also. Both Part B and Part C is open book, so memorization of formulae won't be an issue.

Questions related to Pipe Fittings: -

1. How can flanges be classified based on Pipe Attachment?

 Answer: -

Flanges can be classified based on pipe attachment as: -
Slip – on. : - The Slip-on type flanges are attached by welding inside as well as outside. These flanges are of forged construction.
Socket Weld. : - The Socket Weld flanges are welded on one side only. These are used for small bore lines only.

22. What is the difference between Pipe and Tube?

Answer: -
Pipe is identified by NB and thickness is defined by Schedule whereas Tube is identified by OD & its thickness as BWG (Brimingham wire gauge or 1/100 inch).

23. From which size onwards NB of pipe is equal to OD of Pipe?

Answer: -
From the size 14” and onwards NB = OD of pipe.

24. What should be the radius of long radius elbow?

Answer:
1.5D (Where “D” is the diameter of the pipe.)

25. What should be the radius of short radius elbow?

Answer:-
1D(Where “D” is the diameter of the pipe.)

26. What is the basis of using of short radius & long radius elbow?

Answer:-
Long radius elbow are used for small pressure drop whereas short radius elbow are used for high pressure drops. For catalyst flows vary long radius elbows are used.

27. Normally where do we use the following?

(1) Eccentric reducers.   (2) Concentric reducers.

Answer:
  1. Eccentric reducers = Pump suction to avoid Cavitation, To maintain elevation (BOP) in rack.
  2. Concentric reducers = Pump discharge, vertical pipeline etc.

28. Concentric reducer is used in pump suction. (Yes / No). Explain.

Answer:
No. Air pockets may form if concentric reducer is used at pump suction, which results in cavitation
and cause damage to Pump. To avoid this problem, Eccentric Reducer with flat side up (FSU) is
used in Pump Suction.

Answer: -
Above 18” ERW pipes are used. Below 18” seamless pipes are used. Seamless pipes can sustain
higher temperature & pressure.

31. What is the main use of ASTM A53 & A106 Gr.B pipes?

Answer: -
ASTM A53 pipes are mainly used for utility services whereas A106 Gr. B pipes are used for high
Pressure & high temperature services.

32. From which side of pipe will you take a branch connection?

Answer:- 
When fluid is Gas, Air or Steam and Cryogenic Service – Topside.
When Fluid is Liquid – Bottom Side.

33. Why don’t we take a branch for Cryogenic Service from bottom side though the fluid is in liquid state?

Answer: -
There is the chance of ice formation during normal operation and since ice flows from the bottom of the pipe it will block the branch pipe connection.

33. Why do we provide High Point Vent (HPV) and Low Point Drain (LPD) in piping?

Answer:
HPV – For removing Air during Hydro-test.
LPD – For draining water after conducting Hydro-test.

34. What do you mean by Jacketed Piping?

Answer: -
Piping which is recognized as providing the most uniform application of heat to the process, as well
as maintaining the most uniform processing temperatures where steam tracing is not capable of
maintaining the temperature of fluid constant. Usually used for molten sulphur, Polymers service.

35. What is the minimum distance to be maintained between two welds in a pipe?

Answer: -
The thumb rule is that the minimum distance between adjacent butt welds is 1D. If not, it is never
closer than 1-1/2". This is supposedly to prevent the overlap of HAZs. Minimum spacing of
circumferential welds between centerlines shall not be less than 4 times the pipe wall thickness or
25 mm whichever is greater.

36. What do you mean by IBR and which lines comes under IBR purview?

Answer: -
IBR: Indian Boiler Regulation Act.
Steam lines with conditions listed bellow comes under IBR purview : –
  • Lines for which design pressure is 3.5 kg/sq. cm and above.
  • Line size above 10” having design pressure 1.0 kg/sq. cm and above.
  • Boiler feed water lines to steam generator, condensate lines to steam generator and flash drum.

37. What are Weldolet and Sockolet? And where they are used?

Answer:-
Weldolet and Sockolet are basically self-reinforced fittings.
Weldolet is used for Butt weld branch connection where standard tee is not available due to size
restrictions and the piping is of critical / high-pressure service. Sockolet is used for socket welding
branch connection, which require reinforcing pad.

38. What is the MOC for Superheated high pressure Steam Lines?

Answer:- 
A 335 Gr. P I / P 11, Composition: Cr. – ½ Mo (P1) / 1¼ Cr. – ½ Mo (P11)

39. What is the normal upstream and downstream straight length of orifice flow meter?

Answer: -
Upstream - 15D Downstream - 5D
