Comparative study of TIG and SMAW root welding passes on ductile iron cast weldability
Metalurgija, 2017 This work compares the weldability of ductile iron when: (I) a root weld is applied with a tungsten inert gas (TIG) process using an Inconel 625 source rod and filler welds are subsequently applied using coated electrodes with 97,6%Ni; and (II) welds on ...
