摘要

In this work, the influence of the performance of the welder on the quality of the stringer bead layer of a control welded joint with real-time registration of process parameters is studied. The analysis, identification and description of the problem areas in the welder’s performance that led to the unsatisfactory quality of the stringer bead layer were evaluated. The causes of the errors of the welder related to factors such as: lack of time, physical overload, level of training, psychological state, and sensory deprivation come to the foreground. Real-time monitoring of welding process parameters with the help of modern software and hardware systems allowed to compare statistical data corresponding to defect-free weld sections with similar data of weld sections with defects. The data obtained revealed the causes of defect formation related to violations of welding techniques. At the same time, the welding parameters corresponded to the established values. A methodological approach to determining the influence of the human factor on the reliability of the production system, in particular on reliability indicators such as the probability of failure-free operation of the system and its duration, was proposed. With this approach it is possible to develop specific recommendations for the organization of welding production in order to reduce the influence of the human factor on the quality of welds. These are organizational measures that involve the division of the welder’s work functions according to the type of work between the welder and support personnel (weld inspectors, grinders, and fitters, etc.).
