Investigations on Fume Formation Rate in Shielded Metal Arc Welding Process Using Different Electrodes


Article Preview

Welding is one of the major processes used in the manufacturing industry. The base materials, welding consumable materials and physical and chemical phenomena, which are connected with high temperature and UV radiation, are emission source of welding fumes. The particulate solid dust and various gases are included in welding fumes. This paper addresses the experimental investigation made to study the process parameters on formation and composition of fumes during shielded Metal Arc welding (SMAW) of stainless steel. The process variables include electrode diameter and welding current. It was observed that, the welding current and electrode diameter have a positive effect on the fume formation that is, increase in welding current and electrode diameter caused an increase in the concentration. All the metallic constituents attached to it also exhibited the same behavior.
