3. Definitions and General Provisions 3.1 Definitions. All of the terms listed in this clause are used in various parts of this document and require definition for correct interpretation of the text. Most of these terms are not contained in AWS A3.0, Standard Welding Terms and Defi- nitions, Including Terms for Adhesive Bonding, Brazing, Soldering, Thermal Cutting, and Thermal Spraying. A-numbers. A classification system of weld metal analysis used for procedure qualification. buttering. The deposition of weld metal on one or both faces of the joint prior to preparation of the joint for final welding. Buyer or Owner. The person, company, or agency that purchases the rotating equipment. Engineer. The responsible technical authority. F-numbers. A grouping of electrodes and welding rods based on their usability characteristics, which fundamentally determine the ability of welders to make satisfactory welds with a given filler metal. This grouping system is used to reduce the number of welding procedure and performance qualifications where this can logically be done. Referred to the same as in AWS B2.1/B2.1M, Specification for Welding Procedure and Performance Qualification. Fabricator. The person, shop, Contractor, or agency performing the actual welding. The person may be employed by the Manufacturer’s company or the Fabricator may be an independent shop doing work on a subcontract basis. Referred to as the Employer in AWS B2.1/B2.1M, Specification for Welding Procedure and Performance Qualification.heat treatment. A combination of heating and cooling operations applied to a metal or alloy in the solid state to obtain desired conditions or properties. Inspector. The person designated by the Manufacturer, Owner, or Repair Organization who shall ascertain that all fabri- cation by welding is performed in conformance to the requirements of this specification. M-numbers. A classification system that groups base metals for welding procedure and performance qualification on the basis of mechanical properties, chemical composition, and metallurgical compatibility to minimize the number of welding qualifications where this can logically be done. Under this system, base metals have been divided into gen- eral categories (e.g., Material numbers M-1, M-1A, M-2, M-2A, M-3, etc.) and further subdivided into groups. Referred to the same as in AWS B2.1/B2.1M, Specification for Welding Procedure and Performance Qualification.Manufacturer. The person, company, or agency responsible for the design and performance of a rotating component. Referred to as the Employer in AWS B2.1/B2.1M, Specification for Welding Procedure and Performance Qualification. postweld heat treatment. Any heat treatment subsequent to welding. temperature maintenance. Practice of maintaining a specified temperature for some specified time interval after weld- ing is finished or until postweld heat treatment is initiated, if postweld heat treatment is required. Repair Organization. The organization that provides repair or modification to a rotating component. Referred to as the Employer in AWS B2.1/B2.1M, Specification for Welding Procedure and Performance Qualification. User. The person, company, or agency that utilizes the rotating equipment.4.1.1 Materials selected for use in welded fabrication of rotating elements shall conform to the specifications estab- lished by a recognized material specifying organization (i.e., ASTM, ASME, API, etc.). Materials other than those so covered may be used upon agreement between Owner and Manufacturer, Fabricator, or Repair Organization.AWS D14.6/D14.6M pdf download.
