In the dynamic world of welding, the American Welding Society’s (AWS) Certified Welding Inspector (CWI) credential stands out as one of the most prestigious and sought-after certifications. This credential signifies that the holder has demonstrated the required knowledge, skills, and abilities to excel in this critical role.
The Role of a Certified Welding Inspector
As a CWI, individuals are responsible for ensuring that welded structures and components meet the specified acceptance criteria outlined in various codes, standards, and other requirements. These professionals play a pivotal role in maintaining safety, reducing risk, and ensuring that projects adhere to technical specifications developed by AWS industry experts.
CWIs are expected to possess a deep understanding of welding processes, procedures, welder qualifications, materials, and weld testing limitations. Additionally, they must be skilled in reading blueprint drawings, preparing and maintaining records, generating reports, and making sound judgments.
Certification Process and Requirements
To become a CWI, candidates must pass a comprehensive three-part examination, which includes the Fundamentals Exam, the Practical Exam, and the Code Book Exam. Each component is designed to assess the candidate’s knowledge and proficiency in various aspects of welding inspection.
Becoming a Certified Welding Inspector (CWI) requires candidates to successfully complete a rigorous three-part examination process administered by the American Welding Society (AWS).
Part A: Fundamentals Exam
The Part A Fundamentals Exam is a computer-based test that consists of 150 questions covering a wide range of topics, including:
- Destructive Testing
- Fabrication Math
- Safety in Welding
- Metallurgy
- Nondestructive Testing
- Understanding Welding Symbols
- Welding Procedures and Qualifications
- Welding Fundamentals
Part B: Practical Exam
The Part B Practical Exam is a hands-on assessment where candidates perform various welding-related activities and answer 46 questions related to those tasks. The activities include:
- Application of Welding Procedure Specifications (WPSs) and Procedure Qualification Records (PQRs)
- Use of Inspection Tools and Methods
- Execution of Required Welds
Part C: Code Book Exam
The Part C Code Book Exam is an open-book test that evaluates the candidate’s ability to locate and understand information in specific code books, such as:
- AWS D1.1 – Structural Steel Code
- API 1104 – Welding of Pipelines and Related Facilities
- AWS D1.2 – Structural Aluminum Code
- AWS D1.5 – Bridge Welding Code
- AWS D15.1 – Railroad
- AWS D17.1 – Aerospace
- ASME BPVC Section IX, B31.1, and B31.3
- ISO Standards
To successfully earn the CWI credential, candidates must achieve a minimum score of 72% on each of the three exam parts.
The comprehensive nature of the CWI certification process ensures that holders of this credential possess the necessary knowledge, skills, and abilities to effectively perform welding inspections and maintain the highest safety standards in the welding industry.
To be eligible for the CWI certification, applicants must meet specific education and work experience requirements. These include a combination of formal education, such as a bachelor’s degree in welding engineering or technology, and relevant work experience in the welding industry.
Maintaining the CWI Credential
The CWI certification is valid for nine years, after which the holder is responsible for managing the renewal and recertification processes. This ensures that CWIs stay up-to-date with the latest industry developments and maintain their expertise.
The renewal process involves providing the necessary documentation and making the required payments, while the recertification process may involve passing additional exams or completing specific endorsements.
The Significance of the CWI Certification
The CWI credential is highly valued in the welding industry, as it demonstrates the holder’s commitment to excellence, attention to detail, and dedication to maintaining the highest safety standards. By employing or contracting CWIs, organizations can enhance their safety protocols, reduce risk, and ensure that their welding projects meet the stringent requirements set forth by industry experts.
