Body of Knowledge


For CWI’s and SCWI’s (3 and 6 year cycles):

The renewal process is an important part of maintaining your certification. SCWI’s and CWI’s maintain their certification by submitting an approved renewal application to the Certification Department. The application must be submitted by the expiration date of the current certification and no earlier than 11 months prior to the expiration date of that certification.

To qualify for renewal, the CWI or SCWI shall attest to having no period of continuous inactivity greater than two years during the previous three years of certification in activities described in AWS B5.1. This work experience must be documented in the Qualifying Work Experience section of the application. Resumes are not accepted.

A 60-day administrative extension period is allowed. During this time, certification will be considered as expired. Renewals submitted after the administrative 60-day grace period but within one year of expiration may be accepted for renewal; however, administrative late fees may apply. If all renewal requirements have been met, certification will be reactivated.

AWS may send a renewal notice, but if not received, it remains the responsibility of the SCWI or CWI to renew on time.

For further information concerning the CWI or SCWI certification renewal, please refer to AWS QC1.


As an AWS Senior Certified Welding Inspector, you must renew your certification every three years. Every nine years, you must recertify, by one of options indicated below. An approved 9-year recertification application must be in the AWS Certification Department by the expiration date of the current certification and no earlier than (11) months prior to the expiration date of the current certification.

A 60-day administrative extension period is allowed. During this time, certification will be considered as expired. If the paperwork is received on time and all renewal or recertification requirements have been met, certification will be reactivated.

  1. 9-Year Recertification by taking Parts A&B of the SCWI Exam: Candidates will need to test to both Parts A&B of the SCWI exam and achieve at least the minimum 72% composite average to recertify. Reference the SCWI Body of Knowledge for a list of acceptable preparatory materials.
  1. 9-Year Recertification by Endorsement: You can take an endorsement exam to recertify. You can apply for this option up to (11) months prior to your expiration date. Passing one of these exams meets the requirements for recertification. Endorsements require passing a two-hour exam on one of the following:

AWS D1.1 Structural Steel
AWS D1.2 Structural Aluminum
AWS D1.5 Bridges
AWS D15.1 Railroad
AWS D17.1 Aerospace
API 1104 Pipelines
ASME Section IX, B31.1 and B31.3 Boiler & Pressure Vessel
ASME Section VIII, Div. 1 & Section IX Boiler & Pressure Vessel
Structural Drawing Reading

All endorsement exams (with the exception of Structural Drawing Reading) will be offered all over the US in convenient locations using computer based testing with our partners at Prometric. After your application has been submitted to AWS and approved, you will be provided with an Authorization to Test (ATT) letter in order to schedule your appointment through Prometric at one of their centers. Prometric session fees will apply at the time you schedule your appointment.

Important Note: AWS QC1 defines endorsements as "Indication of an additional skill documented in writing and added to one's certification credential(s)". In fulfilling the 9-year recertification requirement, endorsements cannot be taken to the codebook to which your CWI certification was attained.

  1. 9-Year Recertification by Accumulated Continuing Education: If you have kept yourself up to date in the inspection profession by attending classes and seminars related to welding, your education requirements may be satisfied. You need 80 contact hours (PDHs) of seminars, courses or online courses such as those found through American Welding Online ( that meet the requirements of QC1 Section 16.

The course content must be in one or more of the subject areas as defined in the Education and Experience Requirements of the B5.1, Specification for the Qualification of Welding Inspectors Section 5.

  1. Endorsements or Certifications Achieved Prior to 9-Year Recertification:
  • Endorsements: Certified Welding Inspectors who have previously taken and passed one or more endorsement exams prior to the nine-year cycle may apply for recertification without having to meet further examination, professional development hour, or seminar requirements.
  • Certified Radiographic Interpreter: At any time during your nine-year cycle, if you meet the prerequisites, you can apply to become certified as an AWS Certified Radiographic Interpreter (CRI). This is a valuable certification that fulfills your nine-year requirement.
  1. 9-Year Recertification Course: If your certification expires within the next seven (11) months and you aren’t going to recertify through examination or haven’t accumulated 80 PDHs in the past nine years, the AWS 9-year recertification course is for you. Upon completion of the course, you will receive an AWS Certificate of Completion for the course. Your new wallet card, certificate, and stamp will be mailed to you. Your certification number and renewal month will not change.

Note: DO NOT mail the full 9yr Recertification application if completing the online registration.
