National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Engineering Control of Welding Fumes.

PB88205935

Publication Date	1974
Personal Author	Astleford, W.
Page Count	124
Abstract	An experimental investigation was conducted to define satisfactory criteria for the control of welding and cutting fumes using local exhaust ventilation methods. Based on the tests with breathing level fume samples, shielded manual metal arc welding on carbon steel and stainless steel, and gas shielded arc welding on carbon steel were judged to constitute the greatest potential health hazards. Analysis of breathing zone fume samples indicated that the prevailing standard of capture velocity, i.e. 100 feet per minute, is extremely effective on controlling fume concentrations. Ventilation system requirements were derived on the basis of a given set of ground rules which included environmental conditions and base materials. Recommendations are made for development of criteria for welding in confined spaces, welding with mixed facilities, and welding on paint-primed and zinc coated base metals.
