Abstract

PURPOSE: To shorten the leaving time after gas sealing to improve the detection sensitivity, by detecting leakage of detection gas from the external after detection gas is sealed under the state where a part of the internal welding line of the joint welding part is not welded, in leakage test.
CONSTITUTION: In the leakage test method for the welded structure such as vessel 10 keeping internal pressure, part 12 of 100mm or less at approximately 1Wseveral mm intervals where internal welding line 11 of the welding part of the joint forming the cavity is not welded is provided and is set to welding residue, and this part is arranged in several positions. Meanwhile, external welding line 13 is welded completely. After sealing detection gas, leakage test is performed from the external. Detection gas invades the cavity of the joint and so on from nonwelded part 12 rapidly; and if a detect exists in welding line 13, detection gas is detected rapidly. Nonwelded part 12 is allowed to weld after leakage test.
