Certified Welding Inspector Exam Prep Course - Minnesota

How Does our CWI Exam Prep Course Work?

Our CWI Exam Prep Course follows the blended learning philosophy. Our course is a combination of online and hands on training.

The course begins with a 60-hour online series of modules that students can move through at their own pace.

Each module includes PowerPoint presentations with in depth discussion by an instructor, ‘flashcard reviews’ and graded quizzes so you can evaluate your progress throughout the course. All of AINDT’s practice quizzes are pulled from our vast exam bank consisting of several hundred questions. Our online portion of the CWI Exam Prep Course provides in-depth training on the following critical topics:

Part A Fundamentals Online

Part B Hands-on

The AWS CWI NEW Part B portion of the exam has elevated the difficulty of flaw evaluation and specification interpretation. Because of this, AINDT offers an onsite 40-hour prep course specifically devoted to the Part B hands-on evaluation of practical weld specimens, WPS/PQR evaluation and interpretation to Part B specific documents used in the CWI Exam.

Included with the online training will be a walkthrough of the Book of Specifications to ensure that students have a full understanding of the purpose and usage of this “mock” specification and how it is utilized for the hands-on Part B. Additionally, AINDT has developed our own version of the Book of Exhibits and Weld Replicas which aligns with the CWI Exam. We will address how the Part B exam is structured and provide ample time examining the weld replicas using the same tools that will be provided by AWS during the exam. Our primary focus will be on measuring and evaluating the weld replicas, however we will also continuously review both Fundamentals and Code requirements to ensure all parts of the CWI body of knowledge is fresh in your head on exam day.

Following the onsite training, you will be provided the opportunity to take the AWS CWI exam at our facility the Saturday immediately following our CWI Exam Prep Course.

Part C Code Book Online

Navigating and understanding technical welding standards can be a daunting task, that is why we include an in-depth review of each clause with insight from an experienced instructor who has worked to these standards which will better help you understand the meaning and reason behind various requirements.

The code book online training will include a walk through of the welding code of your choice. Included in this training will be a review of how best to become proficient at code navigation, with tips on tabbing, highlighting and notes to include in your code. Currently our Part C training consists of either AWS D1.1-2015 or API 1104-21st edition.

Practice Exams

Upon completion of each part of the online training, students will be provided a timed exam replicating the Parts A and C of the CWI exam. This exam will be graded the same way as the CWI exam and may be taken as many times as the student wants. All of our exam questions are pulled from an exam bank ensuring that you will receive a combination of different exam questions each time.
