The joining technique of FeCrAl-ODS stainless steel is considered to be the indispensable technology in the development of the accident tolerant fuel cladding for LWRs. In this study, the strength of end cap joining part welded by the conventional EB weld was measured and X-ray CT checks were performed to the end cap joining part to obtain the relationship between the strength and the microstructure. The end cap welding condition was considered from the obtained results.
