Inconel 713C precision castings are used as aircraft engine components exposed to high temperatures and the aggressive exhaust gas
environment. Industrial experience has shown that precision-cast components of such complexity contain casting defects like
microshrinkage, porosity, and cracks. This necessitates the development of repair technologies for castings of this type. This paper
presents the results of metallographic examinations of melted areas and clad welds on the Inconel 713C nickel-based superalloy, made by
TIG, plasma arc, and laser. The cladding process was carried out on model test plates in order to determine the technological and materialrelated
problems connected with the weldability of Inconel 713C. The studies included analyses of the macro- and microstructure of the
clad welds, the base materials, and the heat-affected zones. The results of the structural analyses of the clad welds indicate that Inconel
713C should be classified as a low-weldability material. In the clad welds made by laser, cracks were identified mainly in the heat-affected
zone and at the melted zone interface, crystals were formed on partially-melted grains. Cracks of this type were not identified in the clad
welds made using the plasma-arc method. It has been concluded that due to the possibility of manual cladding and the absence of welding
imperfections, the technology having the greatest potential for application is plasma-arc cladding.
