Q. Which functions used for coating?
• Improves arc stability by providing certain chemical which have this ability, by ionizing the path of arc.• Provides a protective gaseous atmosphere to prevent O2, H2 and N2 pick-up by the molten metal.• Provides a protective slag over hot metal.• Provides flux, which helps to remove oxides and other impurities from the molten weld metal.• Reduces spatter of weld metal- when coating burns off slower than core.• Acts as deoxidizers.• Adds alloying elements.• Increases deposition efficiency.• Slows down the cooling rate of weld (due to protective layer of slag) to prevent hardening.• Coatings are normally insulators of electricity and so permit the use pf electrodes in narrow grooves etc.
