Evaluation of operational parameters role on the emission of fumes

Industrial health, 2018

Electric arc welding is a routine operation in the construction of metallic structures, but the fumes generated during the welding process can threaten the health of welders. Fumes are undesirable products of the majority of welding operations and may have various detrimental effects on health. The purpose of this study was to investigate the effect of operational parameters of the shielded metal arc welding (SMAW) process on the emission of fumes. A dust monitor was used to measure the number and mass concentration of fumes generated by SMAW. Measurements were made at the distances of 23 cm (hood inlet) and 41 cm (welder's breathing zone) from the weld point, with different values assigned to three operational parameters, namely current intensity, travel speed, and heat input (HI). Number concentration (NC) decreased with the increase in particle size. The highest mass concentrations (MC) were observed for MC1 (0.35-0.5 μm) and MC8 (Larger than 6.5 μm). For reducing exposures t...

Welding Fume Production as a Function of Electrode Coating Composition

2008

All welding parameters are optimised to achieve satisfactory weld joint quality. Electrode coating at MMAW (metal manual arc welding) procedure has several functions: electric, metalurgical and protective function. During MMAW welding significant amount of welding fume is generated. Chemical structure of welding fume depends of welding consuments engaged in process. Many components of welding fume are hazardous for welders’ health and enviroment. Quantity and chemical composition of welding fume are determined by european standards. Changing coating structure affects on welding fume chemical composition. Electrode coating structure differs by manufacturer.
