Title
Specification for Filler Metals for Brazing and Braze Welding

American Welding Society

Publication Date:
Jan 1, 2004

Scope:

This specification prescribes requirements for the classification of filler metals for brazing and braze welding. It includes filler metals for brazing with or without a flux and in all protective atmospheres for various applications, including those for vacuum service.(Footnote 1) The prefix "RB" indicates that the filler metal is suitable for use both as brazing rod for braze welding and as a brazing filler metal.

Safety and health issues and concerns are beyond the scope of this standard and, therefore, are not fully addressed herein. Some safety and health information can be found in the nonmandatory annex sections A5 and A10. Safety and health information is available from other sources, including, but not limited to, ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes, and applicable federal and state regulations.

This specification makes use of both U.S. Customary Units and the International System of Units (SI). The measurements are not exact equivalents; therefore, each system must be used independently of the other without combining in any way when referring to material properties. The specification with the designation A5.8 uses U.S. Customary Units. The specification A5.8M uses SI Units. The latter are shown within brackets [ ] or in appropriate columns in tables and figures. Standard dimensions based on either system may be used for sizing of filler metal or packaging or both under A5.8 or A5.8M specifications.

Footnote 1. - Filler metals for vacuum service are for devices operating in vacuum service, regardless of the atmosphere used in making the joint.
