An inspection method for a welded joint formed between a pair of base metals () with a groove part () and an abutment face () being formed on a joint surface Wc between the pair of base metals. The method includes the steps of: forming a recessed groove () opening to a surface of the base metals in advance at one end of the abutment face; irradiating the joint surface Wc with an X-ray generator () placed on a groove part formation side (an exterior space O side) toward the joint surface Wc after at least one pass Pof build-up welding is performed on the groove parts (); and determining the presence or absence of incomplete penetration in the welded joint part W based on an image formed on a photosensitive film () by radiation penetrating the joint surface Wc.
