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 r epresent 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, oper ating behaviour, all weld metal propel ties, and diffusible hydrogen in the deposit. It is only recently that information of this kind has become avai lable las, 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 t o 1997. The aim is to contribute to a better understanding of the metallurg y of weld metal deposited by C-Mn steel welding electrodes.
