scope:

1.1 Scope. This specification presents the minimum fabrication and quality requirements for the furnace brazing of materials such as steels, stainless steels, nickel, nickel alloys, copper, copper alloys, and heat- or corrosion-resistant materials as well as other materials that can be adequately furnace brazed. Note that the furnace brazing of aluminum alloys is addressed in AWS C3.7M/C3.7, Specification for Aluminum Brazing. The purpose of this specification is to standardize furnace brazing process requirements and brazed joint quality requirements for all applications requiring brazed joints of assured quality. This document establishes minimum requirements for processes and products with a minimum of explanatory information so that sources of ambiguity are minimized. It assigns responsibility for the ultimate quality of the brazed product to a single organization and permits that organization to modify requirements if appropriate to the application. It requires proper documentation of any such modifications. 1.2 Units of Measurement. This standard makes use of both the International System of Units (SI) and U.S. Customary Units. The latter are shown in brackets ([ ]) or in appropriate columns in tables and figures. The measurements may not be exact equivalents; therefore each system must be used independently. 1.3 Safety. Safety and health issues and concerns are beyond the scope of this standard; some safety and health information is provided, but such issues are not fully addressed herein. Safety and Health information is available from the following sources: American Welding Society: (1) ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes (2) AWS Safety and Health Fact Sheets (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: (1) United States Department of Labor, Occupational Safety & Health Administration (OSHA) (2) Equivalent agencies of other countries and individual states 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 Z49.1 should be considered when developing the safety program. See 5.6 for additional safety and health information. 1.4 Ordering Information. The purchaser shall provide the following information to the brazer: 1) Parent metal alloy and condition 2) Brazing Filler Metal The following information is optional or has default requirements in this document; therefore, the purchaser may specify alternate requirements: 1) Brazed joint classification (Clause 4) 2) Cosmetic criteria 3) Fillet size 4) Areas to be free of excess brazing filler metal 5) Flux type or restrictions on use of flux 6) Heating or cooling rates7) Postbraze heat treatment 8) Pre- or postbraze cleaning methods9) Method of nondestructive examination 10) Name of the Organization Having Quality Responsibility 11) Part Number and quantity of parts
