Abstract:   (1018 Views)

Cellulose is a natural biopolymer with the general (C6H10O5)n formula, which according to AWS A5.5 standard, more than 40wt% of coating of cellulosic electrodes is consisted of cellulose. In this study to evaluate the effect of cellulose type on the performance of E8010-P1 cellulosic electrode, equal  amounts  of two celluloses with the same commercial properties but produced by two different companies, were used for production of two E8010-P1 electrodes.Experimental studies illustrate significant difference between structural and mechanical properties of deposited weld metals from these electrodes. FTIR, DTA and XRD testes of as-received celluloses show despite the same brandforthese celluloses, their properties such as bonds types,thermal behavior and crystallinity are different that cause variation ofweld metal penetrate and tensile strength around 25±2% and 5±2%respectively.

Keywords: E8010-P1, cellulose, weld penetration, microstructure, FTIR, XRD, DTA.
