This can easily lead to strip breaking at the weld seam in the cold rolling process. In this paper, a finite element model of roll and strip with weld seam is established to investigate the mechanism of strip breaking at weld seam due to thickness difference. By simulating the working conditions in the rolling process for weld seam with different thickness differences, the evolution of the stress state of the weld seam in the rolling process under each working condition is analyzed. The influence of thickness difference in the rolling process of the weld seam is revealed, and the effect of thickness difference on the risk of strip breaking at weld seam during the rolling process is further discussed. According to the research results, the optimization method of strip head and tail shear length was designed and applied to the industrial site. After application, the accident rate of strip breaking is reduced and the effect is as expected. <\/jats:p>","DOI":"10.1142\/s1793962323500228","type":"journal-article","created":{"date-parts":[[2022,6,17]],"date-time":"2022-06-17T09:14:13Z","timestamp":1655457253000},"source":"Crossref","is-referenced-by-count":1,"title":["Research on the effect of thickness difference of weld seam on strip breaking during rolling in PL-TCM"],"prefix":"10.1142","volume":"14","author":[{"given":"Zedong","family":"Wu","sequence":"first","affiliation":[{"name":"National Engineering Technology Research, Center of Flat Rolling Equipment, University of Science and Technology Beijing, Beijing 100083, P.
