Effects of Basic Electrode Coating Formulation on Fume Emission Rate and Composition in Manual Metal Arc Welding of Steel

TWI Industrial Member Report Summary 319/1986

By G J Carter

Background

The project has examined variables affecting fume emission during manual metal arc (MMA) welding with emphasis on the effect of electrode formulation on fume emission rate and composition. The overall aim has been to define important factors in the design of consumables providing reduced emission rate and fume toxicity. Following earlier work on the welding of steel using rutile consumables, the present report describes studies relating specifically to basic consumables.
