摘要： A method of manufacturing a shrouded turbine blade is disclosed. In an embodiment, the method comprises casting a shrouded turbine blade including a shrouding. The shrouding includes an abutment face. The method includes welding a coating composed of a different material than the shrouded turbine blade onto the abutment face. The method includes applying hot isostatic pressing to the abutment face after welding the coating. The hot isostatic pressing is sufficient to heal internal defects in the abutment face. The method includes machining the shrouded turbine blade after applying hot isostatic pressing.
