The test results found that the increase in grain size of the coarse, heat-affected zone decreased the hardness of the welded joint by about 30 HV. The tensile strength of the repair-welded joints was reduced by 20 MPa compared to the welded joints. For the high cycle fatigue behavior, the fatigue life of repair-welded joints is lower than that of the welded joints under the same dynamic load. The fracture positions of toe repair-welded joints were all at the weld root, while the fracture positions of the deck repair-welded joints were at the weld toe and weld root, with the same proportion. The fatigue life of toe repair-welded joints is reduced more than that of deck repair-welded joints. The traction structural stress method was used to analyze fatigue data of the welded and repair-welded joints, and the influence of angular misalignment on was considered. The fatigue data with and without AM are all within the \u00b195% confidence interval of the master S-N curve.<\/jats:p>","DOI":"10.3390\/ma16103682","type":"journal-article","created":{"date-parts":[[2023,5,12]],"date-time":"2023-05-12T01:30:29Z","timestamp":1683855029000},"page":"3682","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Influence of Repair Welding on the Fatigue Behavior of S355J2 T-Joints"],"prefix":"10.3390","volume":"16","author":[{"given":"Peng","family":"Zhao","sequence":"first","affiliation":[{"name":"School of Ocean Engineering, Harbin Institute of Technology, Weihai 264209, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Banglong","family":"Yu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Advanced Welding and Joining, Harbin Institute of Technology, Harbin 150001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1147-5477","authenticated-orcid":false,"given":"Ping","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Ocean Engineering, Harbin Institute of Technology, Weihai 264209, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Ocean Engineering, Harbin Institute of Technology, Weihai 264209, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoguo","family":"Song","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Advanced Welding and Joining, Harbin Institute of Technology, Harbin 150001, China"},{"name":"Shandong Institute of Shipbuilding Technology, Weihai 264209, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"109304","DOI":"10.1016\/j.engstruct.2019.109304","article-title":"An equivalent structural stress-based fatigue evaluation framework for rib-to-deck welded joints in orthotropic steel deck","volume":"196","author":"Li","year":"2019","journal-title":"Eng.
