ASME BPVC Section IX–An Introduction to Welding Qualification

This course is intended for engineers, supervisors, quality assurance/control personnel, auditors, and other technical personnels.


This online, self-learning course explains the layout, scope, and use of Section IX of the ASME Boiler and Pressure Vessel Code. It explains and demonstrates the rules for qualification of welding procedures and personnel. The course also discusses basic rules for the use of Section IX in conjunction with other construction codes. These rules include the identification of responsibilities for procedure and personnel qualification and which activities can be subcontracted by the manufacturer.

Basic characteristics of the welding processes will be presented as a basis for understanding the essential and nonessential variables that are listed for the qualification of procedures and personnel. Some basic metallurgy will be presented to explain the philosophy supporting the essential variable rules of the Code. Examples of welding procedure and personnel qualification documentation will then be presented showing how the essential and nonessential variables are to be identified and documented. Finally, a brief discussion and demonstration will be conducted to show how supplementary essential variables can be addressed when impact toughness is required.
