本规范规定了保护金属电弧焊用覆盖（焊剂涂层）E1100、E3003和E4033铝合金焊条的分类要求。分类试验是对芯线进行化学分析，以及对坡口焊接试验组件进行拉伸和弯曲试验，每个类别使用两种尺寸的焊条制作。规定了标准电极尺寸、电极标识和化学成分限值。本规范使用美国惯用单位和国际单位制（SI）。由于这些系统并不等同，因此每个系统必须独立使用。

This specification prescribes requirements for the classification of covered (flux coated) E1100, E3003, and E4033 aluminum-alloy electrodes for for shielded metal arc welding. Tests conducted for classiciation are chemical analysis of the core wire as well as tensile and bend tests from groove weld test assemblies fabricated with each of two sizes of electrode for each classification. Standard electrode sizes, electrode identification, and chemical composition limits are specified. This specification makes use of both US Customary Units and the International System of Units (SI). Since these are not equivalent, each system must be used independently of the other.
