The Rutile ElectrodeThe Cellulosic ElectrodeConclusion of The ComparisonAdditional Guidance and Best Practice in The Use of Cellulosic ElectrodesThe difference between the E6012 and E6013 electrodes is that the E6012 covering contains sodium, while the covering of E6013 contains potassium. They can both run under direct current (DC+) but only the latter is suitable for running under alternative current (AC). Working with a constant current is recommended to counterbalance the unsteadiness of the welders hand. With a high proportion of titanium dioxide (also called titania) the rutile electrode gives a smooth bead surface, easily removal slaSee more on twi-globalComparison of the use of rutile and cellulosic electrodes effects of cellulosic and basic flux on the structure(steel) Types of Electrodes and Their CompositionsThe Rutile ElectrodeThe Cellulosic ElectrodeConclusion of The ComparisonAdditional Guidance and Best Practice in The Use of Cellulosic ElectrodesConclusionReferencesMany types of manual metal arc (MMA) electrodes are available on the market. Depending on the main constituent of their flux, they are grouped into three categories cellulosic, rutile and basic. All electrodes consist of a core wire (typically 2.56mm diameter) coated by a flux. The core wire is generally made of low-quality riming steel and the fluxes contain many elements allowing refinement of the weld microstructure.

E6010 electrodes are sometimes called stove pipe electrodes. This position can enhance the weld and helps to improve efficiency and productivity, thanks to quick cooling of the slag.Comparison of the use of Rutile and Cellulosic Electrodes effects of cellulosic and basic flux on the structure

Cellulose and wood flours burn during welding and form carbon oxides, which, as inert gases, protect the weld from oxidation. Since cellulose burns completely, cellulosic coatings produce less slag and are therefore suitable for extreme welding positions.(plate) Competitive Exclusion and Metabolic Dependency among effects of cellulosic and basic flux on the structure(steel) Microorganisms that degrade cellulose utilize extracellular reactions that yield free by-products which can promote interactions with noncellulolytic organisms.

AbstractIntroductionExperimentalResults and DiscussionConclusionThe effect of the concentration of sulfuric acid (SA) and temperature on structure and properties of cellulose (MCC) had been studied. Investigations showed that solubility of the initial sample at the room temperature increased gradually in the range of the acid concentration from 50 to 60wt.% SA. When SA concentration reached 65wt.%, then MCC sample dissolved completely. Cellulose regenerated from 65wt.% SA had an amorphized structure and was characterized by high enzymatic digestibility.
