What is Plasma Transferred Arc Repair Welding of The Nickel-Base Superalloy IN-738LC about?

This document studies the effect of plasma transferred arc welding (PTA) on repairing the nickel-base superalloy IN-738LC. PTA welding was used with various parameters on IN-738LC specimens to study weld-pool shapes, microstructures, and mechanical properties. Results showed PTA welded specimens exhibited 96% tensile strength of the base material and minimized cracking susceptibility through optimized welding parameters.
