The SCWI Certification lasts 9 years, with renewals required at years 3 and 6. AWS sends reminders 6 months and 3 months prior to each renewal. Renewal requires continuous employment in the relevant activities and documented work experience stated in the requirements section. Renewal applications should be sent at least 60 days before the expiration date but can be submitted up to 11 months in advance. If late, a 60-day extension is available, during which the certification is considered "Expired." Applications after this period incur administrative late fees. Once all renewal requirements are met and fees paid, the certification is reactivated.

The renewal application can be completed at MyAWS Portal. Here you may also check your SCWI credentials, application, or exam registration status.

Adding an Endorsement

Endorsements are supplemental inspection credentials available to all AWS Certified Welding Inspectors (CWIs) and Senior Certified Welding Inspectors (SCWIs), that document an individual’s additional knowledge, skill, or ability.

Successful completion of an endorsement exam, taken up to 11 months before the SCWI’s certification's expiration date, satisfies the recertification requirements. However, for purposes of recertification, SCWIs cannot use the same endorsement codebook that was used to obtain their CWI certification.

Select from our catalog the endorsement you are interested in to see requirements, reference materials, and other relevant information. Applicants who choose to submit their application to AWS headquarters via email (PDF) or mail carrier (paper) will be subject to an additional processing fee of $125.

SCWI Recertification Guide

There are several options available to SCWIs wishing to achieve recertification after nine years.

1. Recertification by taking a committee-approved endorsement during the previous nine years of certification.
2. Recertification by achieving sufficient professional development hours (PDHs) during the previous nine years of certification.
3. Recertification by taking the 9-year AWS Recertification Seminar prior to the certification expiration date.
4. Recertification by achieving a previous Certified Radiographic Certification.  

SCWI Recertification by Adding an Endorsement

Adding an endorsement to your SCWI certification is another way to achieve recertification. You can choose one endorsement from a comprehensive list, including but not limited to:

• AWS D1.1 Structural Steel
• AWS D1.2 Structural Aluminum
• AWS D1.5 Bridge Welding
• ASME Section IX, B31.1 and B31.3 Boiler & Pressure Vessel

Please note, the pursuit of an endorsement must be different from the codebook used for achieving your current active CWI certification. All endorsement exams are offered at Prometric Exam Centers.

9-Year Recertification by Accumulated Professional Development Hours (PDH)

A SCWI can accumulate 80 contact hours through seminars, courses, or online platforms like AWS’s Education Portal to fulfill recertification requirements.

Endorsements or Certifications Achieved Prior to 9-Year Recertification

A SCWI who has passed one or more endorsement exams prior to the nine-year cycle can apply for recertification without additional examination or PDH requirements. Additionally, becoming an AWS Certified Radiographic Interpreter (CRI) during the nine-year cycle fulfills the recertification requirement. Learn more about CRI here

9-Year Recertification Course

Another option is to register for and successfully complete the AWS 9-Year Recertification Course.
