AWS F1.6:2017

This document assists companies in estimating emissions from welding processes for EPA reporting purposes by choosing the simplest applicable method and following its steps. Example calculations are included.
Scope : 1.1 Scope. This guide outlines four methods of estimating airborne emissions from the arc welding process. This document does not cover disposal of collected wastes from the welding process, including collected welding fume. Emissions from sources other than the welding consumable (such as zinc oxide from galvanized material) cannot be estimated based upon process or consumable data alone and should be addressed by onsite testing (see 3.3.4). These estimates do not consider gaseous emissions that may be present in welding such as ozone, carbon dioxide, argon, oxides of nitrogen, or other gases. This standard makes sole use of U.S. Customary Units. Approximate mathematical equivalents in the International System of Units (SI) are provided for comparison in parentheses or in appropriate columns in tables and figures. 1.2 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
