Abstract

Abstract. The article presents the results of an experimental study of steel welded belts between saw blades of a 5LP linter machine under tension. The WAW-1000D universal testing machine was used to determine the practical tensile strength of welded steel belts (St3) between the saw blades of the 5 LP linter machine. Analysis of the results of experimental studies of welded steel belts between saw blades with a thickness of 1.5 mm and 2 mm using electric arc welding and kempi – showed that, in order to stretch welded belts up to 5 mm, 2820 N is necessary for a sample of 1.5 mm under arc welding and kempi 2900 N, and for a sample of 2 mm, it is necessary 3260 N for electric arc and 4440 N for kampi welding. The results of studies of welded belts under tension make it possible to use gaskets of electric arc and kampi, when welding steel belts. The preference is given to the technology of welding belts of steel gaskets using an electric arc in a carbon dioxide environment - kempi since it provides a minimum thermal stress in the welding zone.
