Automatically performing crack control of non-magnetic forged parts by means of liquid penetrant method with the help of camera

Nowadays, with the decrease of oil reserves, the technology of fuels such as electricity and hydrogen is developing day by day. Recently, with the increase in electric vehicle production in the automotive industry, parts produced from steel alloys used in automobiles have been replaced by lighter alloys such as aluminum. It is of great importance to perform crack control of such non-magnetic alloys safely, quickly and economically. Crack control of non-magnetic materials can be performed with liquid penetrant method, which is one of the non-destructive testing methods. The most important feature of the liquid penetrant crack control method, which is superior to other non-destructive testing methods, is that we can apply it economically to non-metal (non-magnetic materials) materials. In this thesis, it is aimed to perform the crack control of forged parts produced from austenitic stainless steel and aluminum raw materials automatically with the help of a camera using the liquid penetrant method. Liquid penetrant applied, non-magnetic forged materials were checked for cracks with the help of a camera, their detectability was verified and a line design was made in order to control in accordance with mass production.
