Emission of Dust and Gases in Tubular Cored Wire Welding of Steel

Matusiak J, Rams B.

International Journal of Occupational Safety and Ergonomics

2003

Vol. 9, No. 3

333--350

The emission of dusts and gases, which are generated during tubular cored wire welding and which are hazardous to health and the environment, were studied. Tests included various kinds of tubular electrode wires used for welding steel, that is, rutile flux cored wires, basic flux cored wires, and metal cored wires for welding unalloyed, low-alloy, and high-alloy steels as well as self shielded flux cored wires used for welding low-alloy steels. The research results make it possible to assess the influence of the type of wire and welding conditions on the emission volume and to compare chemical hazards generated during tubular cored wire welding with those typical for other arc welding processes.
