时效硬化或沉淀硬化合金的设计目的是为工程师提供适用于从剃须刀刀片到航天器等各种产品的材料。本报告总结了焊接这些材料的推荐程序。由于材料的历史和冶金条件已被证明是PH材料成功焊接的主要因素，因此讨论的很大一部分与所涉及的冶金因素有关。奥氏体合金钢A-286的焊接尤其如此。焊后处理在可销售五金件的一致焊接中也极其重要。众所周知，良好的焊缝在热处理和老化过程中会开裂。对于讨论的每种材料，报告概述了一个程序，如果遵循该程序，将产生机械和射线可接受的焊接件。

The age-hardenable or precipitation-hardening alloys were designed to provide engineers with suitable materials for a wide range of products-from razor blades to space vehicles. This report summarizes the recommended procedures for welding these materials. Since the history and metallurgical condition of the material have been shown to be primary factors in the successful welding of the PH materials, a large portion of the discussion concerns itself with the metallurgical factors which are involved. This is especially true of the welding of the austenitic alloy steel A-286. Post-weld treatment is also extremely important in the consistent welding of salable hardware. Sound welds have been known to crack during heat treating and aging operations. For each material discussed, the report outlines a procedure which, if followed, results in the production of mechanically and radiographically acceptable weldments.
