1.范围1。1本标准规定了气体保护电弧焊用固体碳钢填充金属的分类和认证要求。术语“电极”用于GMAW工艺的连续导线。术语“棒”指用于GTAW、PAW和类似工艺的直线长度或连续导线。（另见附录A第A4条。）1.2本标准中分类的焊条和焊条用于气体保护电弧焊。这并不是为了阻止其与任何其他工艺或任何其他保护气体或其合适的保护气体组合一起使用。1.3本标准涵盖的填充金属根据（a）填充金属的化学要求（表1）进行分类；（b）机械性能

1. Scope1.1 This Standard prescribes requirements for the classification and certification of solid carbon steel filler metals for gas-shielded arc welding. The term ""electrode"" is used for continuous wire for the GMAW process. The term ""rod"" refers to straight lengths, or continuous wire, used for GTAW, PAW, and similar processes. (See also Appendix A, Clause A4.)1.2 Welding electrodes and rods classified in this Standard are intended for gas-shielded arc welding. This is not intended to preclude their use with any other process or any other shielding gas, or combination of shielding gases, for which they are found suitable.1.3 Filler metals covered by this Standard are classified according to (a) the chemical requirements of filler metal (Table 1); and (b) the mechanical properti
