Heat treatment of welded joints of gas turbine elements

Our company's specialists were sent on a business trip to the Yamalo-Nenets Autonomous District to perform local heat treatment after completing repair welding work.
According to the technical specifications, the heat treatment of the welded joints was carried out with uniform heating, holding, and constant temperature control throughout the entire heat treatment process. The heat treatment was performed at a heating rate of 150°C per hour, with a holding temperature of 980°C (1 hour), and a cooling rate of no more than 150°C per hour. A similar type of work was performed by our employees in 2018.
During the heat treatment of welded joints, our company's specialists constantly monitor the heating and cooling rates, and the temperature is recorded using reliable temperature recording devices.
