AWS A5.8M-A5.8:2019 pdf download.Specification for Filler Metals for Brazing and Braze Welding
1. General Requirements
1.1 Scope. This specification prescribes requirements for the classification of filler metals for brazing and braze welding. It includes brazing tiller metals for brazing with or without a flux and in all protective atmospheres for various applications, including those for vacuum service. In the case of composite products — flux cored wire or rods. jlu.v-coated rods. iransfir tape’, or paste — this standard covers only the filler metal that forms part of such products.
1.2 Units of Measurement. This specification makes use of both the International System of Units (SI) and (J.S. Customary Units. 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 A5.8M uses the International System of Units. The specification A5.8 uses U.S. Customary Units. The latter arc shown within brackets ([ ]) or in appropriate columns in tables and figures. Standard dimensions based on either system may be used for the sizing or packaging of brazing filler metal, or both, under A5.8M or A5.8 specifications.
1.3 Safety. Safety issues and concerns are addressed in this standard, although health issues and concerns are beyond the scope of this standard. Some safety and health information can be found in non-mandatory Annex B, clauses 135 and 1310.
Safety and Health information is available from the following sources:
American Welding Society:
(1) ANSI Z49. I, Safi’tv in iJWding. Cutting. and Allied Processes
(2) AWS Safety and health Fact Sheets (see Annex B. clause BlO)
(3) Other safety and health information on the AWS website
Material or Equipment Manufacturers:
(1) Safety Data Sheets supplied by the materials manufacturers
(2) Operating Manuals supplied by equipment manufacturers Applicable Regulatory Agencies
Work performed in accordance with this standard may involve the use of materials that have been deemed hazardous, and may involve operations or equipment that may cause injury or death. This standard does not purport to address all safety and health risks that may be encountered. The user of this standard should establish an appropriate safety program to address such risks as well as to meet applicable regulatory requirements. ANSI Z49.l should be considered when developing the safety program.
