For many gas and arc welding processes, the fume concentration in the immediate vicinity of the weld is well above its exposure limit. The amount of fume generated is determined primarily by welding process, consumable and welding procedure. However, the following aspects are likely to influence the degree to which the welder is exposed to fume:

Proper storage of both opened and unopened packages of welding consumables is crucial. It should avoid quality issues such as porosity, excessive slag fluidity, rough weld surface, difficult slag removal and more importantly, elevated levels of diffusible hydrogen which can lead to cracking. Adequate storage, handling and re-conditioning of electrodes vary according to type. The […]
