Abstract

Characteristics of organosilicon sealant of VGO-1 brand, which is employed in the preparation of glue-welded joints through contact welding are considered. Preparation conditions of glue-welded joints are given and it is determined that there is a decrease in the magnitude of welding current and an increase in the time of welding and electrode contact pressure upon welding of steel specimens of 08kp brand by the VGO-1 sealant. Structural studies of the sealant after exposure at various temperatures show that the sealant possesses high frost resistance at –30°C in the air and a satisfactory frost resistance at –50°C in the liquid. The swelling degree of the sealant after 20 days of exposure in medical ethyl alcohol is less than 4.5%.
