Are you gearing up to tackle the AWS Certified Welding Inspector (CWI) exam? If so, you're about to enter the realm of a challenging test that can significantly impact your career in the welding industry. As an American Welding Society (AWS) certification, the CWI exam holds immense value and demands thorough preparation to ensure success.

In this article, I'll share valuable pointers on how to pass the CWI exam, including dos and don'ts based on my personal experience. Let's dive in.

The first crucial step is selecting the appropriate code book to work with. You have two options: the AWS D1.1 and the API 1104. While many may suggest the API 1104 due to its relatively thinner size, I personally recommend using the AWS D1.1, which is the structural steel welding code.

Why choose the AWS D1.1? Firstly, by opting for this code book, you eliminate approximately half of the material, as the second half primarily consists of annexes that are not frequently utilized. Moreover, and perhaps most importantly, the AWS D1.1 code book contains an index at the back, unlike the API 1104. This index serves as a valuable resource when you encounter questions related to specific code sections. Having easy access to the index can significantly aid your navigation through the code book during the exam.

While the choice of code book ultimately lies with you, I strongly suggest utilizing the AWS D1.1. I personally passed the CWI exam on my first attempt at the age of 23 back in 2005 using this code book. On the other hand, I encountered individuals who were attempting the exam for the sixth time while using the API 1104. The difference in approach and outcomes convinced me of the advantages of the AWS D1.1.

Now, let's delve into the structure of the CWI exam. The exam is divided into four parts: Fundamentals, Practical, Code, and an Essay section. Each section grants you two hours, summing up to a total of six hours for the entire exam. Time management is critical during the test, as candidates often underestimate the time required to complete each section.

To optimize your time, I recommend initially going through the questions and completing the ones you can answer quickly. This strategy allows you to allocate more time to the challenging questions later. Many candidates make the mistake of fixating on a single question for an extended period, which can impede progress. Remember, it's difficult to finish within the two-hour time frame per section, so prioritize wisely.

Regarding the Code section, which requires thorough understanding and application, I personally revisited it four times during the exam. Each time, I tackled the questions I was confident about and progressively devoted more time to the trickier ones. Utilize the inside cover of your code book to write notes or add tabs to mark relevant sections. Additionally, highlighting the information you believe may be questioned can serve as a useful strategy.

The CWI exam is undoubtedly challenging, but with meticulous preparation, strategic time management, and a deep understanding of the code book, success is attainable. As you embark on your journey to become a certified welding inspector, remember that diligence and dedication are key.

In the upcoming articles, I will delve further into each section of the CWI exam, providing you with valuable insights and additional tips to bolster your preparation.

Stay tuned for the next installment, where we will unravel the Fundamentals section of the AWS CWI exam.

Understanding the meaning and interpretation of welding symbols is crucial, as they play a vital role in the industry.

Moving on to the Practical section, you'll face a unique challenge. Here, you'll be presented with plastic specimens of weld replicas, accompanied by a separate book that contains the correct code specifications. It's important to note that the plastic specimens may not be entirely accurate, as they may have been tampered with or damaged over time. Therefore, exercise caution and pay close attention to detail when measuring dimensions, assessing discontinuities, or evaluating reinforcement requirements. Consult the accompanying book for accurate information pertaining to each specimen.

The Practical section has proven to be a stumbling block for many candidates. While some found it relatively manageable, others struggled to achieve the desired results. Keep in mind that everyone's experience may vary. It's crucial to invest time and effort into understanding the code and accurately interpreting the requirements for each specimen.

Previously, failing the Practical section meant retaking the entire exam. However, there is a recent change in policy. If you achieve an average score of 72 or higher across all sections and pass two out of the three major sections, you will have the opportunity to retake only the section you failed. This revision offers some respite to candidates and allows them to focus on improving specific areas of weakness.
