To understand the proper use and interpretation of ASME B & PV Section IX Code - Welding Qualifications, this course start with a 2-day review of the Code and the welding portions of related ASME construction codes ( Section I, VIII-1, B31.3), followed by one day of studying the welding metallurgy that ASME IX is based on. It is also intended to prepare exam candidates for the ABSA Welding Examiner Paper #4 on Regulations and Codes and some 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 ABSA Welding Examiner, Pressure Equipment Inspector and CSA W178.2 exam candidates, although it is not a prerequisite that you be an exam candidate.
THIS COURSE WILL COVERED THE FOLLOWING TOPIC :
Safety Codes Acts
- Overview of Design Construction and Installation of Boiler and Pressure Vessel Regulations
- Pressure Welders Regulation
General Review to ASME IX
- general requirements
- procedure qualifications
- performance qualifications
- welding data
Basic Metallurgy of Carbon and Alloy Steels
- basic carbon steel metallurgy
- using the Fe-Fe3C phase diagram in practical terms
- common heat treatments for carbon steel
- low temperature notch toughness and grain size (ASTM No.)

Welding Metallurgy of Carbon and Alloy Steels
- the weld, heat affected zone, preheating and postweld heat treat in practical terms
Base Metal and Filler Metal Specifications
(ASME Section II Parts A and C)
- classification of steels - UNS, SAE, ASTM, ASME
- ASME SA-106, SA-516, SA-333, SA-387, and SA-312
- AWS classification of filler metals, SFA No., F No., and A No.
- ASME SFA-5.1 and SFA-5.5

ASSIGNMENTS, TUTORIALS AND WORKSHOP :
Several workshops covering WPS, PQR and WPQ sample exam questions will be conducted, with take-home assignments handed out at the class. A review of the take home assignments will be covered the following mornings.
Each attendee will participate in a group workshop to write new construction and maintenance welding procedures in accordance with ASME Section I - Power Boilers, ASME Section VIII - Pressure Vessels, ASME B31.1 - Power Boilers and ASME B31.3 - Process Piping. These welding procedures will be reviewed and discussed in detail during the class.
REQUIRED CODE DOCUMENTS :
All participants must bring the ASME Section IX code book to this class.
A course notebook will be provided to all participants.
