THE INFLUENCE OF THE ELECTRODE TYPES ON THE CARBON MONOXIDE FORMATION DURING THE WELDING PROCESS

A study on the dependence of carbon monoxide concentration in working area magnitude welding current and time while using electrodes different types was conducted order to choose methods means for protection welders. An analysis latest research publications air pollution by aerosols gases generated during arc performed. For experimental determination concentrations area, an individual gas detector-analyzer used. The results laboratory conditions full factorial planning FFE2 type experiment are presented. Based obtained regression models, graphical dependences were constructed when most common brands electrodes. It established that largest amount is formed at a 200 with having rutile-cellulose coating, second place - basic third rutile coating; after 5 minutes electric 100 A, larger this coating. make it possible practically modes ensure minimum levels emissions. complex modern solutions reducing given, which consists use neutralization methods, ventilation means, appropriate respiratory protection, as well controlling environment state work.
