ICS Code (Welding, brazing and soldering in general): 25.160.01
ISBN (print): 978-0-87171-820-4
scope:

This code provides qualification, workmanship, and inspection requirements for both arc welding (Part A) and braze welding (Part B), as they apply to the fabrication, manufacture, and erection of nonstructural sheet metal components and systems. 1.1.1 This code was developed to provide standardized requirements for the qualification, production, and acceptance of welding or braze welding of nonstructural sheet metal components. 1.1.2 General applications of this code are in the following industrial areas: (1) Heating, ventilating, and air conditioning systems (2) Food processing equipment (3) Architectural sheet metal and similar applications (4) Other nonstructural sheet metal applications This code covers sheet metal thicknesses up to and including 0.2391 in [6.07 mm]. Also covered are the attachment of accessories and components of the system, and joining or attachment of any member, regardless of thickness, whose sole purpose is stiffening, supporting, or reinforcing the sheet metal. 1.1.2.1 Limitations/Exceptions. This code is not intended to apply: (1) Where negative pressure or positive pressure exceeds 5 psi [30 kPa], which is approximately 120 in [3 m] of standing water (2) Where structural requirements apply (Note: AWS D1.3/D1.3M, Structural Welding Code-Sheet Steel is intended for such applications) (3) Where sheet metal products related to automotive applications are concerned (4) Where brazing qualifications are specified to be in accordance with AWS B2.2/B2.2M, Specification for Brazing Procedure and Performance Qualification (5) Where soldering qualifications are specified to be in accordance with AWS B2.3/B2.3M, Specification for Soldering Procedure and Performance Qualification 1.1.3 This code requires values to be specified by the Engineer for weld type, size, and location of the application. See subclauses 8.2, 8.4, 13.1, and 13.3. 1.1.4 Symbols used in this code shall be in accordance with the latest edition of AWS A2.4, Standard Symbols for Welding, Brazing, and Nondestructive Examination. 1.2 Units of Measurement. This standard makes use of both the U.S. Customary Units and International System of Units (SI). The latter are shown within brackets ([ ]) or in appropriate columns in tables and figures. The measurements are not exact equivalents; therefore, each system must be used independently. AWS D9.1/D9.1M:2018 1.3 Safety. Safety and health issues and concerns are beyond the scope of this standard and therefore are not 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 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 Z49.1 should be considered when developing the safety program
