This is an introductory course that provides a basic understanding of the proper use and interpretation of ASME Section IX - Welding Qualifications Code and its related ASME construction codes. To accomplish this objective, the course starts with a 2-day review of ASME Section IX, followed by one day of studying the base metal metallurgy and welding metallurgy that ASME Section IX is based on. The fourth day covers the welding portions of related ASME construction codes (Section VIII-1, B31.1, and B31.3) and how ASME Section IX interacts with each, including the metallurgy previously covered through a series of workshops. This course is also intended to prepare exam candidates for ABSA Welding Examiner Paper #4 on Regulations and Codes and most parts of Paper #2 covering properties and structures of metals, welding metallurgy and material specifications (i.e., steel manufacturing will not be covered).
Who Should Attend
Inspectors, welders, welding supervisors, quality control personnel, technologists, and engineers involved with new welding procedure and welder qualifications for new fabrication, repairs, maintenance, and inspection for pressure vessel or piping. This course is also designed to assist preparing exam candidates for Alberta Welding Examiner (Papers 2 and 4) and CSA W47.1 Welding Engineer certifications.
CSA W47.1 Welding Engineers:
The CSA W47.1 Suggested Areas of Study for Welding Engineers are covered by the two following CASTI courses that are approved by the Canadian Welding Bureau (CWB):
- ASME Section IX - Welding Codes and Metallurgy (this course), and
- Welding Fundamentals
For more information please see Getting Started: CSA W47.1 Welding Engineer.
Each participant will receive a digital CASTI Certificate of Completion with 32 Professional Development Hours (PDHs) for attending all 4 days of the training course.
