Abstract
PURPOSE:To readily perform the inspection of the welded joints of double tubes by inserting jigs, which comprise fitting a film on the surface of a thin base plate and mountign an expandable or shrinkable bag-form material on the back into the annular part of the double tube and setting the film in the welded joint part by the expansion of the bag.
