Register for CASTI Training Programs
CASTI provides exam preparation training to help candidates pass the CSA W178.2 Level 1 Welding Inspector Certification Exams and the ASME B31.3 (Process Piping) Code Endorsement Exam. Our blended learning program combines online training with practice questions and e-instructor support, and traditional classroom training with hands-on experience using physical weld samples. CASTI training programs are separate from the certification exams, which are administered by the Canadian Welding Bureau (CWB).
Recognition for Exam Exemption
Passing CASTI's CSA W178.2 Level 1 Welding Inspector Preparation Course qualifies exam candidates for exemption from the closed-book "Basic Welding Inspection and Basic Welding Fundamentals" exam. To pass the CASTI course, students must:
- complete and submit all pre-classroom online lessons prior to the course start date and receive an average mark of 70% or more,
- attend all in-classroom training days, and
- receive a minimum mark of 70% on the Welding Inspection closed-book (2 hr) final exam on the last day of the in-classroom training.

What is a CSA W178.2 Welding Inspector?
To perform welding inspection work in Canada, all welding inspectors must be certified to the CSA W178.2 standard. There are three levels of inspectors:
- Level 1 - required to work under the supervision of a Level 2 or Level 3 welding inspector
- Level 2 - able to perform welding inspection independently
- Level 3 - able to perform welding inspection and review contractors' inspection and test plans
It is recommended to review the CSA W178.2 standard for more information on the different levels of welding inspectors.
