Heat treatment of the welds of 4 gas turbine elements

Another successful local heat treatment of welds was performed at the customer's site.  

 Our company's specialists performed heat treatment of the welded joints of four gas turbine elements (two heating zones on each element) with a metal thickness of 10 mm. 

 The correct installation of heating elements, thermometers, and thermal insulation materials ensured uniform heating, holding, and monitoring. 

The heat treatment was carried out at a heating rate of 150 °C/hour, a holding temperature of 980 °C (1 hour), and a cooling rate of 150 °C/hour to a temperature of 400 °C (then under insulation, without monitoring).

 During the heat treatment, the heating and cooling rates, temperature, and holding time were constantly monitored using high-quality temperature control and recording devices.
