Effects of heat input on metallurgical behavior in HAZ of multi-pass and multi-layer welded IN-939 superalloy
The hot components of a gas turbine are susceptible to damage in the high-temperature environment of turbine engine operation. Given that these components are relatively costly to manufacture, they are often repaired than replaced when damaged. Fusion welding is an economical method for repairing th...
