There are two types of front fillet test specimen, one is Splice type, the other is Cross type. But there is difference of breaking strength of the two types, inspite of same sized fillet. Test was then made to study the stress distribution of the two types fillets, and to study above mentioned point by it's result. Thickness of specimens was 10mm, size of fillets were 30mm and 50mm, and those were devided into Splice type (FS) and Cross type (FC). Test Results : According to wire strain gauge, (1) Yielding of fillet went on from inside to outside. (2) Breaking strength of FS were higher than FC, but stress concentration of inside of fillet was inverse. We consider, the difference of stress concentation is due to shape of non-welded slit between base metals each other. (3) Average breaking angle of FS fillet was 24°50' and shape was linear, but shape of breaking fillet of FC was very different from FS. (4) Breaking strength of long spliced specimens were higher than short, inspire of same sized fillet and same FS type.
