AWS A5.32M-A5.32:2011 pdf download.Welding Consumables - Gases and Gas Mixtures for Fusion Welding and Allied Processes
1. Scope
AWS A5.32M-A5.32 specifies requirements for the classification of gases and gas mixtures used in fusion welding and allied processes including, but not limited to:
一gas tungsten arc welding一GTAW;
一gas metal arc welding一GMAW;
一flux cored arc welding一FCA w;
一plasma are welding一PAW;
一plasma arc cutting一PAC;
一laser beam welding一LBW;
一laser beam cutting一LBC;
一arc braze welding一ABW;
一electrogas welding一EGW.
The purpose of this Standard is to classify and designate these gases and gas mixtures in accordance with their chemical properties and metallurgical behavior as the basis for correct selection by the user and to simplifty the possible qualifica-tion procedures. The modes of application for gas shielded welding processes include, but are not limited to: manual,semiautomatic, mechanized, and cautomatic weld methods.
Gas purities and mixing tolerances are specified as delivered by the supplier (manufacturer) and not at the point of use.Gases or gas mixtures may be supplied in either liquid or gaseous form, but when used for welding and alied processes,the gases are always used in the gaseous form.
Fuel gases, such as acetylene, natural gas, propane, etc., and resonator gases, as used in gas lasers, are not covered by thisStandard.
Transportation and handling of gases and containers shall be in accordance with local, national, and regional standards and regulations as required.
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 cannex clause A5. Safety and health information is available from other sources, including, but not limited to: Safety and Health Fact Sheets listed in A8.3, ANSI Z49.1 Safety in Welding, Cutting and Allied Processes', and applicable federal and state regulations.
This specification makes use of both the Intermnational System of Units (SI) and U.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 A5.32M uses SI Units. The specification with the designation A5.32 uses U.S. Customary 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 packaging or both under A5.32M or A5.32 specifications.AWS A5.32M-A5.32 pdf download.
