ASME Section IX (Welding and Brazing Qualifications)

June 13, 2017

 

ASME Section IXScope

ASME Section IX consists of two parts—Part QW and Part QB—which deal with welding and brazing, respectively. In addition, ASME Section IX contains mandatory and nonmandatory appendixes.

ASME Section IX requirements relate to the qualification of welders, welding operators, brazers, and brazing operators and the procedures used in welding and brazing. They establish the basic criteria for welding and brazing observed in the preparation of welding and brazing requirements that affect procedure and performance.

ASME Section IX is a supplemental code. The requirements of ASME Section IX apply when referenced by the governing code or standard or when specified in purchaser’s specification. It is usually referenced in other sections of the ASME Boiler and Pressure Vessel Code and the ASME B31, Pressure Piping Code.

 

Effective Edition, Addenda, and Code Cases

The applicable edition and addenda of ASME Section IX shall correspond to the edition and addenda of the referencing code. However, the later or the latest edition or addenda of ASME Section IX may be used, provided it is acceptable to the enforcement authorities having jurisdiction.

For safety-related items of an operating nuclear power plant, application of ASME Section IX will be in accordance with the requirements of ASME Section XI, Rules for Inservice Inspection of Nuclear Power Plant Components.

For nonsafety-related items, the following guidelines apply:

  • Editions are effective and may be used on or after the date of publication on the title page.

  • Addenda are effective and may be used on or after the date of issue.

  • Addenda and revisions become mandatory as minimum requirements six months after the date of issue, except for pressure vessels or boilers contracted for prior to the end of the six-month period.

  • Code cases may be used beginning with the date of their approval by the ASME.

  • Use of revisions and addenda and code cases that are less restrictive than former requirements must not be made without assurance they have been accepted by the proper authorities in the jurisdiction where the item is to be installed.
