Abstract

PURPOSE: To close the damaged pressure-welded part perfectly and easily by cutting off the pressure-welded part of a plug and pipe hole then again explosively welding said part with a new plug for explosive welding when the part pressure-welding the pipe hole part of a pipe plate and the plug by an explosive pressure welding method is damaged.
CONSTITUTION: A pipe hole of 24mm diameter is perced in a pipe plate 1 of 95mm thickness, and a plug 3 of 2.5mm thickness and 21mm outside diameter (however, the outside diameter on the closing side is 23.8mm) of the same material is inserted therein. A plastic-made case (b) filled with gunpowder (a) is inserted and the gunpowder (a) is exploded by a detonator (c), whereby the plug 3 is pressure-welded to the inside wall of the pipe hole. If at this time the pipe plate 1 side in the position of the pressure-welded part 7 causes work hardening about 0.3mm from the pressure- welded interface and causes cracking or the like, the plug 3 and pipe hole are cut off about 0.5mm with a cutting blade 6 having a guide bar 5 at the end simultaneously. Next, a plug 9 of 2.5mm thickness and 22mm outsiee diameter for reexplosive welding is inserted, and is again explosively welded at the size similar to before, whereby the defective plug is made into a proper plug and the pipe hole is perfectly closed.
