Ductile Cast Iron 350/4 using SMAW
International Journal for Research in Applied Science and Engineering Technology, 2022 Abstract: This article examines the weldability of ductile cast iron when the root weld is applied with a tungsten inert gas (TIG) welding process employing an Inconel 625 source rod, and when thefiller welds are applied with electrodes coated with 97.6% Ni. The welds were performed on ductile cast iron specimen test plates sized 300 mm × 90 mm × 10 mm
