Tension testing of steel welded belts of the saw gaskets of a linter machine

Abstract

The results of tensile testing of steel welded belts of saw blades of a linter machine are presented in the article. A universal testing machine was used to find the tensile stability of steel welded belts of saw gaskets of a linter machine. The results of tensile tests on the study of steel welded belts of gaskets with a thickness of 1.5 mm and 2 mm using electric arc welding and kemppi welding (a carbon dioxide welding technology) showed that in order to stretch welded belts up to 5 mm, 2820 N is necessary for a thickness of belts of 1.5 mm for electric arc welding, and 2900 N for kemppi; with a thickness of 2 mm, 3260 N is necessary for electric arc welding and 4440 N for kemppi welding. The results of the tensile tests of welded belts showed that when welding the belts of steel gaskets, both electric arc and kemppi welding can be used. In the production of steel belts of gaskets, it is appropriate to use kemppi, because the minimum thermal stress is reached in the welding zone.
