Explosive Testing of Welds

Abstract

The objective of this program was the development of an alternative test method for testing sample weld plates for weld procedure qualification, using shaped charges instead of the Ballistic Weld Test Procedure of MIL-STD- 1941(MR). The proposed method would have reduced turnaround time and cost by allowing locally conducted testing, achieving weld test results in a much shorter time. Charge placement would have been accurately controlled, eliminating the need for duplicate samples because impact locations were unacceptable. Testing to date indicates that the charge sizes required to form an impression similar to the ballistic projectile would result in too much noise and ground vibration for local use. Also, the measured weld damage and impression depth do not appear to be consistent with charge size. Keywords: Ballistic weld test procedures; Armor plate; Shaped charges; Projectile impact test; Terminal ballistics; Explosions.
