The investigation focused on the characterization of the microstructure and chemical composition changes after annealing. The research was conducted on the Inconel 625 weld overlay deposited on a boiler steel. The annealing was performed for 10 h at temperatures from 600 to 1000°C. The microstructure and chemical composition were examined by scanning electron microscope and transmission electron microscope equipped with an energy dispersive X-ray spectrometer. Weld overlays were produced by an innovative method of cold metal transfer.
