Abstract
The results of metrological control of welded sheet joints of studies at low-frequency processing are presented. During fusion welding, a field of residual elastic stresses is created in structures, which are extremely unevenly distributed in them. To equalize the stresses, stabilization is performed using special vibration exciters (vibrators) based on low-frequency mechanical vibrations. This provides dimensional stabilization of welded structures made of low carbon steel. The author investigated the process of vibration hardening of welded sheet joints with several combinations of adjustable parameters. As a result, graphs of accelerations and vibration amplitudes of the exciter and the system were obtained. An assessment of the influence of alternating stresses on the value of residual stresses in the welded joint is given. The theoretical studies of the vibration molding process have been confirmed.
