Improving the quality of control of welded joints in the production of mechanical engineering products

The purpose of the work is to develop an automated quality control system for welded joints of cable car structures designed and manufactured at the Skado LLC enterprise (Samara) in order to improve the quality of control. The analysis of requirements for welded structures and welded joints of cable cars is carried out, methods of control of welded joints are considered. A block diagram of an automated system for quality control of welded joints based on the method of ultrasonic testing has been developed. The analysis of ultrasonic sensors on phased arrays is carried out. The sensors and actuators of the system are selected. A scheme for interfacing system elements with a programmable logic controller has been developed. The structure of the system and the scheme of interfacing the system elements with the programmable logic controller are described. A method for performing control has been developed.
