The National Shipbuilding Research Program. Shipyard Welding Emission Factor Development
Abstract
The shipbuilding and repair industry in the United States uses a large variety of rods and wires when joining metal pieces by welding. Additionally, various types of welding processes are also employed depending upon the type(s) of metals being joined and the required performance standard of the weld. Depending upon the types of rod and wire used and the welding process employed, different types and quantities of air emissions will be generated. Some types of emissions that are generated from welding have been recognized as having potential human health effects. The type and severity of these health effects will vary depending upon the duration and concentration of the exposure of any particular hazardous substance. Therefore, in order to more accurately estimate any potential health effect derived from welding emissions, it is important to accurately quantify the emission rate (grams of emission per second of process, when expressed as a function of time; or grams of emissions per lbs of welding rod/wire, when expressed as a function of mass). Atlantic Marine, Inc. (AMI), in association with LFR Levine Fricke (LFR), and Dana M. Austin Environmental Consulting (AECI) conducted a series of tests to develop emission factors for shipyard welding operations. Tests were conducted in a controlled environment where steel components will be welded to simulate typical shipyard welding conditions.
