Welding Fume Production as a Function of Electrode Coating Composition (original) (raw)

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.
