Abstract

1285911 Welding by pressure BABCOCK & WILCOX CO 19 Sept 1969 [20 Sept 1968] 46303/69 Index F2P 23F P27 A plug for obturating a passage comprises a hollow cylindrical body 14 having radially extending flanges 18 and is inserted in a tube 12 with explosive material 31, 32, 33 detonated within the plug to expand a zone of the plug into explosion welded relation with a corresponding zone of the passage wall. The explosive material comprises a block 31 and sheets 32, 33. The plug wall is of uniform thickness except for the end which is firstt inserted which is of increasing thickness towards a closed hemispherical nose 17. Filler pieces 35, 36 of foam plastic are inserted to support the explosive material.
