American Welding Society® CERTIFICATION U.S. CUSTOMARY BOS [aws.org](aws.org) CERTIFIED WELDING INSPECTOR (CWI) PART B PRACTICAL BOOK OF SPECIFICATIONS (BOS) 2017 DO NOT WRITE ON THIS BOOK FOREWORD This Part B Book of Specifications is intended to be used as a reference book for taking the hands-on practical examination that is part of the CWI certification examinations. This practical examination simulates actual hands-on inspection and document reviews performed by the Certified Welding Inspector (CWI) . You are expected to evaluate the acceptability of test specimens and documents for both procedure and welder qualifications and production welding by using standard measurement tools, visual inspection, and documents found in the Book of Exhibits. Acceptability is based upon the information contained in this Book of Specifications. The practical examination will test your ability to carry out these functions. Although this Book of Specifications is formatted to look like a real codebook, it is not a real codebook and it should not be used as one. While some clauses in this Book of Specifications appear to be similar to codebooks that you are familiar with, read this Book of Specifications very carefully and do not rely on your memory to make decisions with regards to answers on this examination. Review the organization of this Part B Book of Specifications. There are specific clauses that relate to workmanship and visual inspection criteria in three applications: Structural, Pipeline, and Pressure Piping. There are general clauses for inspection, procedure, and performance qualification that apply to all three applications. As this Book of Specifications applies to three applications, terms and definitions are not limited to AWS A3 .0, Standard Welding Terms and Definitions. In addition to the main body of the specification, there are annexes, tables, and figures that are important in your examination decisions. They are numbered uniquely so as to avoid confusion. Make sure that you have located all the necessary annexes, tables, and figures before you answer any question. A Book of Exhibits is used in the exam and contains examples of various documents and photos including but not limited to WPS’s, PQR’s WQTR’s, heat treat charts, and NDE methods. Neither the test specimens nor the Book of Exhibits are available for review prior to the examination. For some questions, narratives will give you information upon which you will be asked specific questions. The question may make reference to locations on certain specimens included in your test kit or refer to documents within the Book of Exhibits. In addition to the Book of Exhibits, all test kits have standard measuring tools necessary to complete the examination. IMPORTANT 1. Read each question carefully and completely, including every choice provided. There will only be one correct answer. Be careful to transfer your choice of answer to the correct location on the answer sheet. 2. The weld replicas in the assigned test kit are made of plastic to assure that every test candidate receives the exact same specimens. As a consequence of the replication process, there may be color variations from actual weld metal and visible seams from the plastic assembly process. Ignore any pinholes, seams, glue squeezed out, or color variations in your determination of a correct answer. 3. You are expected to know how to use and apply each measuring and inspection instrument in the examination kit including knowing how to properly zero the instrument where relevant. 4. Use the margins or blank pages in your examination booklet to perform any required calculations. Do not write in this booklet. This page is intentionally blank.
