9% nickel alloy steels used for shell plate of LNG storage tanks are welded with dissimilar inconel hastelloy welding rod and the weldment shows similar characteristic with the dissimilar metal weld of low carbon steel and austenitic stainless. Abnormal-type indications are sometimes shown on the film during radiographic testing of the weldments. In this study identified whether real indications or abnormal-type indications using mask, double film by X-ray and γ-ray, also proposed radiographic film interpretation and cause of abnormal-type indications
