Guide for Estimating Welding Emissions for EPA Ventilation Permit Reporting
standard by American Welding Society, 02/25/2003
This guide outlines methods of estimating airborneemissions from the arc welding process. This documentdoes not cover disposal of collected wastes from thewelding process, including collected welding fume.Emissions from sources other than the welding consumable(such as zinc oxide from galvanized material) cannotbe estimated based upon process or consumable dataalone and should be addressed by onsite testing (Method4). These estimates do not consider gaseous emissionsthat may be present in welding such as ozone, carbondioxide, argon, oxides of nitrogen or other gases. Thisdocument does not discuss safety issues; for moreinformation, see ANSI Z49.1, Safety in Welding, Cutting,and Allied Processes. This standard makes use of theU.S. Customary Units. Approximate mathematicalequivalents in the International System of Units (SI) areprovided for comparison in parentheses ( ) or in appropriatecolumns in tables or figures.
