8、ng in Building Construction, was published by the American Welding Society in 1928. Since that time, the D1.1 has undergone numerous revisions, upgrades, and name changes, ultimately culminating in the latest version: AWS D1.1/ D1.1M:2015, Structural Welding Code Steel. Individuals who seek certific

9、ation as a Certified Welding Inspector (CWI) need to select a code for the Part C: Code Applications Exam. This Code Clinic Reference Manual (CCRM) is designed to guide individuals through the D1.1/D1.1M:2015 code and provide them with the strategies and skills necessary to competently navigate the

10、D1.1 code in an exam or at work. From here forth, the use of D1.1 implies the D1.1/D1.1M:2015 edition. While many of the techniques and advice provided in this reference manual can be applied to virtually any code and specification, the information contained herein is meant to solely reference the A

11、WS D1.1. This edition of the D1.1 Code Clinic Reference Manual supersedes previous editions of the CCRM. The skill set obtained through this program, as either part of the AWS Certified Welding Inspector Seminar or through individual self-study, will allow individuals to quickly and accurately ident

12、ify specifications related to their current code work. The purpose of the D1.1 Code Clinic Reference Manual is both to prepare the individual to sit for the “Code Applications Exam” portion of the Certified Welding Inspector examination or the D1.1 endorsement exam. Endorsements are supplemental ins

13、pection credentials available to all AWS Certified Welding Inspectors (CWIs) and Senior Certified Welding Inspectors (SCWIs) to enhance an individuals credentials. For instance, a CWI or SCWI may demonstrate competency in additional AWS, ASME, or API codes and list this endorsement on their wallet c

14、ard. OBJECTIVES The express purpose of the Code Clinic Reference Manual is to instruct the reader on efficiently and effectively navigating the D1.1 code. By the end of the program the reader should be able to: 1) Identify the nine (9) clauses of the D1.1 code and describe the content of each clause

15、. 2) Effectively implement the system taught in this reference manual for identifying keywords. 3) Utilize the index, table of contents, and list of tables and figures to identify specific areas of the code. 4) Differentiate information located in the D1.1 text, tables, and figures. 5) Prepare the D

16、1.1 code for a given examination by tabbing and highlighting the appropriate sections. 6) Confidently, efficiently, and accurately navigate the D1.1 code. WHAT THIS BOOK IS NOT While the D1.1 Code Clinic Reference Manual is designed to provide a thorough examination of navigation techniques and meth

17、odologies, the CCRM is not: 6 1) A short cut. Simply reviewing this reference manual will not substantially help you pass the exam. Individuals should be able to understand and apply criteria from the D1.1 code. HOW TO PREPARE? Preparing for the D1.1 Code Applications Exam, much like the layout of t

18、his workbook, is divided into five phases: 1) Understanding the exam and the code 2) Familiarizing oneself with the individual clauses 3) Strategizing techniques for answering questions 4) Preparing oneself and the authentic copy of the D1.1 code 5) Practicing, practicing, and practicing UNDERSTANDI

19、NG The Code Clinic Reference Manual begins with an analysis of the D1.1 Code Applications Exam and a basic overview of the code structure, which are the foundation of this program. These topics are reviewed in Chapters 2 and 3 respectively. Chapter 2 “Putting the Test into Perspective” provides a de

20、tailed description of the D1.1 Code Applications Exam structure, making a direct connection between the exams body of knowledge and how to prepare for it. The chapter enables the readers to: See the exam from the test makers perspective. Understand the way AWS has structured the test, including the

21、type of questions, exam length, and time requirements. Develop fundamental testing strategies, such as exam pacing and benchmarking. Chapter 3 “The Code: An Overview” facilitates the utilization of the code by breaking down its structure and major components. The chapter includes: A basic top-level

22、overview of each of the 9 major clauses, including the major topics and topic areas. A description of the codes clauses, including their interrelationships, allowing the reader to view the code from a practical perspective and thereby locate information more efficiently and accurately. FAMILIARIZING

23、 The next 9 chapters, 4 through 12, provide an in-depth description of the 9 clauses in the D1.1 code: General Requirements, Design of Welded Connections, Prequalification of WPSs, Qualification, Fabrication, Inspection, Stud Welding, Strengthening and Repair of Existing Structures, and Tubular Stru

24、ctures. It should be noted that Clause 9, “Tubular Structures,” is a new clause for the 23rd edition. 7 The tubular provisions, tables, and figures were removed from the other clauses and condensed into this new clause, and a corresponding new commentary was created in the Commentary to AWS Structur

25、al Welding Code Steel section of the code. Each chapter focuses on a single clause and identifies: The purpose of the clause. Why is this clause necessary? What information can be found in this clause? The structure of the clause. What are the major topics? What information is found in the text, tab

26、les, and figures? The important topics. What information is especially relevant to a welding inspector and where is that information located? STRATEGIZING Chapters 13, 14, and 15 will equip the reader with test taking strategies geared specifically to the AWS D1.1 Code Applications Exam. These chapt

27、ers focus on utilizing the codes structure to the readers advantage in locating the pertinent information in the most efficient manner. Chapter 13 “Attacking the Question” provides: Strategies to help the reader understand the questions prompt. What is the question really asking? Strategies for iden

28、tifying the keywords in a question. What words should the reader use to start looking for an answer? Chapter 14 “Using the Index and Table of Contents” provides: Strategies for locating information efficiently in the code. What are the most efficient ways to refer to the Index and Table of contents?

29、 How does the reader determine whether to refer to the Index or Table of Contents first? Chapter 15 “Text, Tables, and Figures” provides: Strategies for predicting where an answer will be found within a clause. Should the reader expect the answer to be found in a section of text, table, or figure? T

30、ogether these 3 chapters provide an effective system for quickly locating information in the D1.1 code that will transcend the exam itself, and provide a systematic approach that can be efficiently utilized in the field. PREPARING The last chapters of the code clinic, Chapters 16 and 17, focus on he

31、lping you prepare yourself and the D1.1 code for the certification examination. Chapter 16, “Tabbing and Highlighting,” covers the dos and 8 donts on tabbing and highlighting the D1.1 code. Chapter 17, “Test Taking Tips”, includes general test taking tips that are critical for any multiple choice ex

32、am (the D1.1 exam included) as well as strategies that can be used to put oneself in the right mind-frame before and during the exam. PRACTICING The single most important aspect of preparing for the D1.1 Code Applications Exam is practice, practice, practice. The last section of the clinic contains

33、3 sample D1.1 tests of varying length and complexity that can be used to practice for the exam while simulating a test day environment. 9 Chapter 2 Putting the Exam into Perspective What is Being Tested? . Exam Pacing Its not about Getting an “A”. . Breaking Down the D1.1 Code Applications Exam 10 W

34、elding inspectors have a wide range of duties, and they play an essential role in welding quality before, during, and after welding. A welding inspector needs to be able to interpret and assess the conformance of documents such as welding procedure specifications, welding procedure and performance q

35、ualification records, material/weld mechanical testing reports, and inspection procedures and reports to a set of requirements like the D1.1 code. A “code” is a systematic set of specifications, methods, guidelines, and best practices organized into one standard for a defined range of industrial app

36、lications, like steel structures, bridges, pressure vessels, or pipelines. The D1.1 Code Applications Exam assesses the individuals competencies to navigate, identify, understand, and apply the code using “open book” questions. Individuals are expected to bring and use their own authentic copy of th

37、e D1.1 code (which is also improperly referred to as a codebook or code book) while taking the exam. AWS allows test takers to prepare their authentic copy of the D1.1 code in any method they choose prior to taking the D1.1 Code Applications Exam. Chapter 16 of this workbook will provide general met

38、hods for tabbing, highlighting, and preparing your code. The first step in preparing for any examination is putting the exam into perspective by identifying the number of questions on the exam, the time allotted for completion, the required passing rate, and the type(s) of questions. D1.1 Code Exam

39、Facts Number of Questions Time Allotted Passing Score Type of Questions 46-60 2 hours 72% Multiple Choice Image 2.1 Establishing this baseline of information will allow test takers to develop efficiency and time management strategies, as well as allow them to walk into the exam with a positive mind-

40、frame. Chapter 3 examines the D1.1 Code Applications Exam structure and content at length, providing test takers with a positive first step in the development of a preparation plan. What is Being Tested? Preparations for an exam should always begin by asking the simple question: “What is being teste

41、d?” Oftentimes, test takers focus too much on the exam topics, and not enough on the “desired outcome.” AWS recognizes that in a real world scenario, welding inspectors would never be expected to memorize the D1.1 code. Therefore, measuring a test takers ability to memorize the particulars of the co

42、de would not be an accurate representation as to how well they would fulfill their job duties. Instead, AWS designed the D1.1 Code Applications Exam to measure how efficiently the test taker can understand the question being asked, locate the appropriate information, and interpret the code criteria.

43、 In other words, it measures how well the test taker can navigate and apply the code. 11 A test takers time is better spent developing navigational strategies and understanding the code layout, and learning what sections of what clauses apply to inspectors duties. Test takers need to pay attention t

44、o details as many clause requirements have essential criteria listed in tables, figures, footnotes, or via cross-references. Test takers need to learn how to use the index fast to locate the correct criteria based on the question, interpret the relevant requirements (or criteria), and then carefully

45、 select the best answer. Exam Pacing While AWS does not provide the exact number of questions that will appear on the D1.1 Code Applications Exam, they do provide a range. As of the printing of this book, the D1.1 exam will contain between 46 and 60 multiple choice questions. AWS certification exams

46、, including the Code Application Exams, are designed by expert volunteers from the welding industry. These volunteers vigilantly monitor exam results and test takers feedback in order to ensure the most relevant, accurate, and complete tests possible. At times, the volunteer committees may find it n

47、ecessary to change the parameters of a given exam. Always verify information, such as the question number range, with the certification exam information on AWSs Certification webpage and the information the Certification Department mails to all exam participants. The D1.1 Code Applications Exam, muc

48、h like all AWS certification exams, is a timed test. Test takers are provided 2 hours to complete as many questions as possible. Combining the time allotted with the range of possible questions provides test takers with a key piece of information: time allotted per question. Calculating the “time al

49、lotted per question” will dictate the testing pace for the exam, ensuring that test takers effectively manage their time. In order to calculate the “time allotted per question,” divide the total time allowed by the number of questions on the test. The answer will be in a decimal format. The whole number equals the number of minutes. Take the remainder and multiply it by 60 to determine the number of seconds. For example, 120 minutes 46 questions = 2.60. The whole number 2 equals 2 whole minutes. The value of .60 when
