Abstract

In this study, the effect of Si content in rutile coating of shielded metal arc welding (SMAW) on mechanical properties, especially on impact toughness, is presented. In this investigation, four rutile-coated electrodes of the AWS A5.1 E6013 type were prepared by reducing silicon gradually in their coatings without exceeding the AWS A5.1 and ISO 2560 limits. Four test pads were prepared using the four electrodes with different compositions to determine the mechanical properties of the welds. Tensile and Charpy V-notch tests were conducted in order to determine mechanical properties. Experimental results showed that the impact toughness of E6013 weld metal at -20 0C improved by reducing silicon. The results suggested that decreasing Si content increased slag basicity and kept, or even improved the typical excellent operational characteristics of E6013-type electrodes.
