Underwater Explosive Welding Using Detonating Code

Abstract:

Detonating code, which is a flexible code with an explosive core, is normally used to transmit the ignition of explosives with high detonation velocity 6 km/s. Therefore it is difficult to use detonating code for the explosive welding of common metals toward the detonating direction since the welding velocity exceeds the sound velocity of metals. Hence, an explosive welding method using underwater shock wave generated by the detonation of detonating code was tried. In the present investigation, the details of the experimental setup and results are reported. And the welding conditions are discussed through numerical simulation. From these results it is observed that the above technique is suitable to weld thin metal plates with relatively less explosives.
