Development of Laser Welding Techniques for Joining Armor.

Abstract

The laboratory feasibility of heavy penetration laser welding was recently demonstrated in low strength steel. The objective of this program is the establishment of laser welding process parameters that will produce a sound, cost-effective joint with ballistic potential in 1-1/2 in. armor plate. Sufficient production, test, and operational data will be prepared to permit a detailed analysis of the achievement of this objective and repeatability of the process. Ballistic testing is not within the scope of this initial work. The program material is MIL-A-12560C(MR) (Mn-Mo) 1-1/2 in. armor plate. The program welding electrode is MIL-E-19822. A 20 deg V-joint will serve as the initial configuration for laser filler wire welding. Work will be accomplished with a 10.6 micron beam from a 15 kW CO2 laser.
