A Study on Fume Generation Rates and Particle Size Distributions at Flux Cored Arc Welding on Stainless Steel

  • 9

A study was conducted for the effects of currents and voltages on the fume generation rates at CO₂ flux cored arc welding on stainless steel. Fume size distributions were also studied. Experiments were run in well designed welding fume box. Six types of flux cored wires were used and three levels of currents and voltages were given. Fume generation rates of domestic flux cored wires are 0.2-0.3 g/min at the lowest input energy and 0.81~0.85 g/min at the highest input energy tested. Fume generation rates could be related to the welding current with secondary power function and to the input energy with primary power function. Flux cored wires, when melted by arc, transfered into the deposited metal(82 ~92% ), slag(9~13% ), spatter(l~6% ), and fume(0.5~1 % ) respectively. Fulx cored welding fumes are all respirable particulate mass.
