This document provides methods for determination of welding heat input, both in the case of traditional welding systems and those employing waveform-controlled welding. It is intended that this specification be referenced by other qualification and fabrication welding standards requiring the measurement and calculation of heat input for maintenance of distortion and weldment properties such as strength, toughness, and corrosion-resistance.

This specification provides the requirements for qualification of Brazing Procedure Specifications (BPSs). This specification also provides requirements for the performance qualification of brazers and brazing operators. This specification is intended for use where referenced by a product standard or contract document. Employers shall be responsible for the brazing done by their organization, including the use of qualified brazing procedures, qualified brazers, and qualified brazing operators. It is the Employer's responsibility to assure that BPSs meet any additional requirements of the Referencing Document. Each Employer shall maintain the applicable BPSs, Brazing Procedure Qualification Records (BPQRs), and Brazing Performance Qualification (BPQ)s during the period of their use. When not otherwise specified by the Referencing Document, the edition of this specification to be used shall be established in accordance with the following: (1) editions may be used at any time after the effective date of issue; (2) the latest edition of this document should be used for new contracts; (3) editions established by contract date may be used during the entire term of the contract, or the provisions of later editions may be used when agreed upon by the contracting parties. This document is intended for use with the following brazing processes: (1) Torch Brazing (TB) (2) Furnace Brazing (FB) (3) Induction Brazing (IB) (4) Resistance Brazing (RB) (5) Dip Brazing (DB) (6) Infrared Brazing (IRB) (7) Diffusion Brazing (DFB)

This Recommended Practices is a collection of data and procedures that are intended to assist the user in setting up resistance welding equipment to produce resistance welded production parts. While the recommendations included are not expected to be final procedures for every production part or every welding machine, they serve as starting points from which a user can establish acceptable welding machine settings for specific production welding applications. In some cases, recommended machine data is not available. In these instances, some description of the process is given to assist the reader in determining if the process might be suitable for the application.
