AWS C3.3 PDF

These recommended practices encompass those procedures that should be followed in the design, manufacture, and examination of brazed joints for critical components in order to assure their reliability in service.

The procedures recommended represent the best current practice and are necessary to the control of brazed joint quality. These practices are applicable to all products and brazing processes. Whenever any or some of these practices are omitted when producing critical components, the omission should be the result of a rational decision, not the result of a lack of knowledge of the best practice.
