AWS Certified Welding Inspector (CWI)

Introduction

This course is preparing Welding Inspectors for the American Welding Society (AWS) Examination, in order to certify them as “AWS Certified Welding Inspector”. This course is a combination of the following three courses which jointly constitute this Certified Welding Inspector Exam Preparation course: - 1. Fundamental Welding Inspection Preparation Course: This course is designed as a preparation for the AWS CWI (QC-1) Exam, part A, Fundamental Welding Inspection Exam. The participant will learn how to take the exam and the basic fundamentals of welding inspection. Information for inspector training is emphasized in this dual goal course 2. Practical Welding Inspection Preparation Course: This course is designed as a preparation for the AWS CWI (QC-1) Exam, Part B, Practical Welding Inspection (hands-on) Exam. This course is a must for the nine-year renewal CWI. The participant will learn how to use the tools required for the exam, as well as the AWS Specifications Book 3. API 1104 Preparation Course: This course is designed as a preparation for the AWS CWI (QC-1) Part C Code Book Exam. The participant will learn how to use the code book to solve inspection problems.  The participant will receive in-depth instruction pertaining to passing the AWS CWI (QC-1) exam, as well as insight into the intricacies students may expect to encounter in the working environment. This course is offered as both an in-house and an open enrollment class. Additionally, quizzes are given at the end of each section; homework is handed out at the end of each class day, and is reviewed at the beginning of the following day, and a practice” exam is administered at the end of the course.

Objectives

By the end of this training course, participants will be able to:

• Prepare for the AWS welding inspector exam and have enough knowledge and skills to pass such exam in order to get the AWS Welding Inspector Certification
• Discuss the aspects of welding inspection, CWI and CWE tests as well as the skills, responsibilities and qualities of an effective inspector
• Carryout safe practices for welding inspectors as well as the method of metal joining and cutting processes
• Identify the weld joint geometry and welding symbols including the features, terminology and application
• Employ documentation governing weld inspection and qualification and describe the metal properties and destructive testing
• Distinguish the various metric practices for welding inspector
• Explain the welding metallurgy for the welding inspector, weld and base metal discontinuities and illustrate visual inspection and other NDE methods and symbols
• Recognize welding of pipelines and related facilities in accordance with API 1104
• Use tools properly for measuring and weld examination

Training Methodology

This training course will be conducted along interactive training principles. There will be a variance of lectures and practical individual and group exercises. Experiences from different areas will be discussed. There will be many opportunities for discussion and sharing experiences.

Who Should Attend?

The course is intended for inspection, piping and welding engineers who are seeking AWS CWI (QC-1) certification. Other engineers, managers and technical staffs who are dealing with welding and fabrication will also benefit.
