Welding is one of the processes which cause multivarious problems to health. It requires considerable attention because of its severe hazards. During welding very harmful fumes and heat are emitted which have adverse effects on the health of the welder and people working in his vicinity. In the present work microfibre glass filter paper (GF/A) was found to be the preferable media for sampling of the fumes from mild steel electric welding electrodes for the evaluation of the trace elemental composition of the fumes. Using neutron activation analysis considerable amounts of the most harmful elements such as Ba, Co, Cr, Sb, Rb, Sc, As and Fe were observed.
