IMPORTANT: All exam candidates must apply directly to the American Welding Society (AWS) to write the examination. This course helps candidates prepare for the code endorsement exam only.

Why Should I Attend

Additional code endorsements strengthen professional credentials and creates more job opportunities by widening the inspector's scope of qualification.


To prepare participants to write the ASME Section IX, B31.1, and B31.3 code endorsement exam for AWS Certified Welding Inspector (CWI) and Senior Certified Welding Inspector (SCWI) certifications.


Each participant will receive a certificate with 1.6 Continuing Education Units (CEUs) accredited by the International Association of Continuing Education and Training (IACET) for completing all online lessons and practice exams.

Who Should Attend

Participants who want to obtain the AWS CWI certification or supplement their AWS CWI and SCWI inspection credentials.

This course will also assist active AWS CWI and SCWI certification holders who intend to pursue reciprocity towards a CSA W178.2 Welding Inspector certification. AWS inspectors should be aware that CSA W178.2 limits inspectors to work within their specific code endorsement certifications. However, code endorsements under your AWS certification will also be recognized for reciprocity.

For information regarding the AWS-CSA reciprocity for welding inspector certification, please visit AWS Certified Welding Inspector career path page for more details.
