Abstract

This specification covers brazing, inspection of brazed joints, and qualifying of brazers, brazing operators, and brazing procedures. <br><u>Criticality</u>. - Brazing performed to this specification shall be classified by criticality as follows: <br>a. Class A - Critical Application. A brazed joint is critical where a failure of any portion would cause loss of system, loss of a major component, loss of control, unintentional release of critical stores, or hazard to personnel. (Except as defined otherwise on the engineering drawings or in the procurement documents, all brazing shall be considered Class A.) <br>b. Class B - Semicritical Application. A brazed joint is semicritical when the failure would reduce overall efficiency of the system but loss of system or hazard to personnel would not be experienced. <br>c. Class C - Noncritical Application. A brazed joint is noncritical where failure would not affect system efficiency or create hazard to personnel. <br><u>Processes</u>. This specification covers requirements applicable to the following brazing processes: <br>a. Torch brazing <br>b. Furnace brazing <br>c. Induction brazing (except aerospace tubing fittings as defined in KSC-SPEC-Z-0006) <br>d. Resistance brazing <br>e. Dip brazing <br>f. Infrared brazing<b><u>Intended Use:</u></b> This specification covers brazing, inspection of brazed joints, and qualification of brazing procedures, brazers, and brazing operators for general brazing in Classes A, B, and C.<br>
