Fume generation in CO2 arc welding by flux-cored wire.
QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 1984 The effects of welding parameters and wire compositions on the fume emission rate of CO2 arc welding by flux-cored wire, have been studied. In addition, high-speed photographs of the welding arcs have been observed in relation to an investigation of fume generation mechanism.As the welding current and arc voltage are raised the fume emission rate ...
