Characterisation of a low hydrogen electrode - role of coating factor on the welding performance and resultant properties
Low hydrogen electrode, coating factor, tensile strength, impact toughness, corrosion behaviour
Low hydrogen electrodes corresponding to E7018 were produced with three different coating factors. The effect of coating factor on the performance of the welding electrode and properties of resultant weldments was assessed. Midst the low (LCF-1.575), medium (MCF-1.770) and high (HCF-2.075) coating factor electrodes produced, the HCF electrode offered better shielding effect; however, it did not provide the best toughness. The relatively inferior impact properties of HCF welds are on account of inclusions, arising from higher quantum of slag, and associated cleaning issues. On the other hand, the inadequate shielding caused the poor impact properties of LCF welds. The corrosion behaviour of these weld metals (LCF, MCF and HCF) seems to be influenced by the cleanliness (inclusion level) and, in general, the weld metals showed inferior corrosion resistance compared to the parent metal.
