Questions and answers
Is Section IX a standalone code?
Section IX is a qualification standard. Construction codes (Section I, Section III, Section VIII, etc.) reference Section IX whenever they require qualified welding, brazing, or fusing procedures and personnel.
Do I need Section V along with Section IX?
Section IX qualifies the procedure and personnel; Section V provides the nondestructive examination methods used during fabrication and inspection. Many code-compliant programs use both together.
Does Section IX cover plastic fusing?
Yes. In addition to welding and brazing, Section IX includes qualification rules for plastic fusing procedures and personnel.
