INVESTIGATION ON WELDING FUMES FROM COVERED ELECTRODE AND DEVELOPMENT OF LOW FUME ELECTRODES
In recent years, there has been an increasing number of papers published on fumes as more importance is attached to welding fumes from the covered electrodes. This paper deals with the investigation of the quantity, chemical composition and shapes of fumes from the covered electrodes commonly used in Japan, analysis of the relationship between the chemical composition of the covering and the fume generation, and considerations on reduction of fumes. Eventually, three types of fume controlled covered electrode were developed on the basis of the information and knowledge obtained through these experiments. For this investigation, sixty one brands of covered electrodes for both mild steel and high tensile strength steel were selected. Diameter of the electrode was 5 mm.
