This course focuses on imparting a comprehensive understanding of ‘stated’ and ‘implied’ requirements (i.e. Content and Intent) of the Welding Qualification code. The candidates would gain insight into ASME Section IX to facilitate interpreting, understanding and complying with the Code rules. The program covers a quick review of common welding processes, their merits and demerits, detailed methodology of Procedure and Performance Qualifications; step by-step explanation for preparation of WPS, PQR and WPQ records. The course covers detailed Road Maps for the review of welding qualifications for different Processes, and extensive case studies for application of the Road Map. Attendees will come away from this course with a clear understanding of the methodology of using Section IX and how code requirements are to be ad-dressed. Emphasis will be placed on writing welding procedures, prepare welding specifications and welder qualifications.

By the end of this course delegates will be able to:

• • To introduce participants to the purpose and methodology of Welding Qualifications
  • Learn how to understand, interpret, and comply with ASME Section IX requirements
  • How to conduct Procedure and Welder Tests, and certification of welders
  • To provide step-by step approach in preparation of WPS, PQR, and WPQ records
  • To know Essential, Non-essential and Supplementary Essential Variables, and their use
  • Review welding processes / variables and basic welding metallurgy
  • Review, scrutinize and accept or reject sub-contractor’s Welding procedures and Welders

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 ABSA Welding Examiner, Pressure Equipment Inspector and CSA W178.2 exam candidates
