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 with edges
tapered at angles of 60◦
.
