Relationships between coating composition,all weld metal properties,operational behaviour,and diffusible hydrogen in weld metal from rutile electrodes of types ANSI/AWS A5.1–91 E6013 and E7024
Manual rutile electrodes of types ANSI/AWS A5.1– 91 E6013 and E7024, which represent the highest percentage by weight of the total production of manual electrodes, have been manufactured for many years. Nevertheless, there are few publications of systematic studies to relate coating composition, operating behav iour, all weld metal properties, and diffusible hydrogen in the deposit. It is only recently that information of this kind has become available (as, for example, for E7018 electrodes). The present work is intended to summarise and review all studies on manual rutile electrodes presented in Subcommission II–A of the International Institute of Welding from 1994 to 1997. The aim is to contribute to a better understanding of the metallurgy of weld metal deposited by C–Mn steel welding electrodes.
