Ultrasonic Weld Sealing of M55 Stab Detonators

Abstract

Ultrasonic ring welding was investigated as a means for hermetically sealing the M55 detonator, in an effort to find a more economical, less labor- intensive method of sealing. The current method utilizes the manual application of lacquer for sealing, which is tedious, subject to non-uniformity and requires a separate work station. Ultrasonic welding did not provide reproducible leak- tight welds because of the lack of rigid support in the detonator configuration for adequate clamping force application during welding. An alternative which would offer a higher probability of success, would be to alter the detonator configuration to provide an outside flange on the cup, so that the cover disc can be welded t o the flange. In this configuration, a solid anvil can support the flange thereby enabling the application of a suitable clamping force.
