  • Content of Cr and Cr (VI) in a welding fume by different Cr content in an experimental coating of a Cr-Ni rutile electrode = Vsebnost Cr in Cr (VI) v varilnem dimu pri različni vsebnosti Cr v plašču rutilne elektrode Cr-Ni

    In the SMAW welding process welding fumes are generated, harmful to human health and the environment. A welding fume is a mixture of gaseous and solid phases, which are generated during most of the ... electric-arc-welding processes. This article presents the researches of the particles that constitute the solid-phase-welding fumes. The change in the chemical composition of an electrode and its components (the coating and the core) can affect the chemical composition of the particles in welding fumes. The largest amount of fumes, about 80 %, is generated from electrodes and, accordingly, the focus of research was the influence of the chemical composition of an electrode on the chemical composition of the welding-fume particles. This paper presents the research results obtained for the content of Cr and Cr (VI) oxide particles in welding fumes. The experimental work on six variants of commercial electrodes E 23 12 2 LR 12, a welding chamber collecting fume particles and a chemical analysis of the particles were applied according to the standard EN15011. The aim was to determine an experimental welding electrode that should generate the welding-fume particles with the lowest content of Cr and Cr (VI) oxide.
