铍铝合金具有良好刚度、密度和热学特性，主要应用于航空、航天等军工领域。铍铝合金精密铸造会存在缩松、热裂、渣孔、气孔、浇不足、尺寸偏差等缺陷，焊接是修补缺陷最直接、最有效的方法之一。铍铝合金焊接产品使用原料仅为加工产品的20%，同时也减少了许多后续处理，国内通过技术攻关，克服了铍铝合金的焊接的技术难点，铸造产品缺陷的修复，逐渐实现了力学性能与本体相当，能够有效地控制虚焊、裂纹、焊透性、豁口等缺陷。其次，对于许多形状复杂，性能要求较高的铍铝产品来说，单纯的铸造已不能满足性能需求，可以通过高性能铍铝部件进行焊接组装获得近净形产品有较高的实用价值。本规范填补了国内外在金属铍检验领域的空白，对提升金属铍铝合金材料研发、应用与生产，提供有力支撑。
