Mastering Armor Steel Welding for Combat Vehicles

These metals perform exactly as designed when welders follow qualified procedures and control the heat
May 2026
By: BRENT WILLIAMS

Modern ground combat vehicles are being redesigned for a battlefield that demands lighter, smarter, and tougher platforms. This shift has accelerated the use of high-strength, low-alloy (HSLA) quenched-and-tempered armor steels, such as MIL-DTL-12560 rolled homogeneous armor (RHA) and MIL-DTL-46100 high hardness armor (HHA).

While these materials offer exceptional ballistic performance, their engineered strength and toughness depend on strict control of heat during welding. This article explains how these ste..
