Air Emissions Factors and Quantification

AP-42 Chapter 12: Metallurgical Industry - Frequent Questions

I would like to estimate emissions from electric arc welding operations for a client, but I could not find an emission factor for the electrode type in their operation. I have already checked tables 12.19-1 and 12.19-2 of AP 42. Any suggestions?

Select the welding rod that comes closest to the welding rod your client is using. Be sure to have them select a rod that is flux coated if their rod is flux coated and vice versa. Be sure to have them select a rod that can be used to weld the same base metal that they are welding.
