This guide outlines 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 (Method 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 document does not discuss safety issues; for more information, see ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes. This standard makes use of the 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 or figures.
