I completed my internship at CTN GROUP, which manufactures machinery and machinery equipment for iron and steel, cement and power plants, under the Quality Control Engineering unit. In this process, I closely examined the processes carried out under Project Engineering and Production Engineering. In the Quality Control unit, I observed and experienced the measurement and reporting of the produced parts, ndt processes, welding processes and painting processes, as well as the quality control of these processes and the preparation of the quality file.
