回顾了超高强度钢（220000-300000 psi）的发展，并开发了用于其制造的焊接金属。提出了六种不同类型的超高强度焊缝金属，并对以下性能进行了研究:横向和全焊缝金属拉伸和屈服强度、延展性、硬度、横向和纵向弯曲性能、夏比V型缺口冲击测量的韧性、Jominy硬度、晶粒度测定和Lehigh约束裂纹试验。 大多数试验都是在不同温度下回火的焊缝金属上进行的。

The development of ultra-high-strength steels (220,000 - 300,000 psi) is reviewed and weld metal developed for use in their fabrication. Six different types of ultra-high-strength weld metal are proposed and the following properties investigated: Transverse and all-weld metal tensile and yield strengths, ductility, hardness, transverse and longitudinal bending properties, toughness as measured by the Charpy V-notch impact, Jominy hardness, grain size determination and Lehigh restrained cracking tests. Most of the tests were made on the weld metal tempered over a wide range of temperatures.
