In spite of the strong demands for the establishment of joiningtechnology between F82H and SUS316L,there have been severalstudies about this dissimilar joint [5–9].Nogami et al.[5] reportedthat F82H and SUS316L could be successfully butt welded by usingelectron beam where the electron beam (EB) has to be shiftedto SUS316L.Also,Hara et al.[6] suggested that,by shifting EB appropriately,the weld metal consisted of the austenitic phase,so that the mechanical properties of F82H/SUS316L joint mightbe improved.In addition,the authors revealed that F82H/SUS316Lbutt-joint could be generated using high-power fiber laser insteadof EB and the composition of weld metal became the mixture ofaustenitic and ferritic phases by shifting the laser beam to SUS316L[7].Moreover,Furuya et al.[8] indicated that F82H and SUS316Lcould be welded by using TIG welding where a filler metal type-Y309 was employed and there were not any harmful weld defectssuch as overlaps,undercuts or macro-cracks and micro-cracks.Meanwhile,Fujii et al.[9] reported that F82H and SUS316 platescould be lap jointed by using the friction stir welding (FSW) anda sound dissimilar joint could be obtained with a smooth jointinterface and no mixed microstructure by controlling the joiningtemperature precisely.
