E-mail: inpat59@ukr.netThe paper discusses approaches to assessing the quality of both the welding process itself and the defects that arise during it. The prospects for using the acoustic emission (AE) method to control the welding process and assess the condition of welded joints are shown. The results of previous AE studies during static tensile testing of metal samples to complete failure and during the welding process using the EMA technical diagnostic system are analyzed. The high sensitivity of the AE method to the occurrence and development of defects is demonstrated. Promising tasks for the development of welded joint control using modern AE systems, automation of the process of control and decision-making regarding the quality of welding and the determination of welded joint defects are identified. 19 Ref., 1 Tabl., 2 Fig.
