... Vessel Code that applies to nuclear components. Every stage of the fabrication was stringently controlled, as were the choice of parent metal and filler wires. The root pass of the fillet weld was made by the tungsten inert gas welding, followed by manual metal arc welding with basic coated electrodes...

.... In addition, GPU also communicated that the weld was a single “V” type with a shallow (≃ 20°) edge preparation. The filler metal used was an E308 Grinnell Consumable Insert and welded with ER308 electrode ( Table 1 ). The welding process used was GTAW (Gas Tungsten Arc Welding). The repair area was in its R-2...
