标准摘要
[中文适用范围]: 本文件规定了可用于点焊、缝焊和凸焊工艺的焊接工艺规范鉴定的测试。 注:这些程序是针对压花凸焊而编写的。 它们也适用于固体突出,例如螺母焊接、螺柱焊接。 交叉丝焊接。 本文件规定了本文件涵盖的所有实际焊接操作的测试条件和合格焊接工艺的有效性限制。 它涵盖 ISO 4063 中定义的以下电阻焊工艺: ——21 – 电阻点焊; ——211——间接点焊; ——212——直接点焊; ——22——电阻缝焊; ——221——搭接缝焊; ——222——压缝缝焊; ——223——预搭接缝焊; ——224——线缝焊; ——225——箔片对接缝焊; ——226——带钢缝焊; ——23——凸焊; ——231——间接凸焊; ——232 – 直接凸焊。 [外文原描述]: This document specifies the tests which can be used for qualification of welding procedure specifications for spot, seam, and projection welding processes. NOTE The procedures are written for embossed projection welding. They can be adapted for solid projections as well, e.g. nut welding, stud welding. cross wire welding. This document defines the conditions for carrying out tests and the limits of validity of a qualified welding procedure for all practical welding operations covered by this document. It covers the following resistance welding processes, as defined in ISO 4063: — 21 – resistance spot welding; — 211 – indirect spot welding; — 212 – direct spot welding; — 22 – resistance seam welding; — 221 – lap seam welding; — 222 – mash seam welding; — 223 – Prep-lap seam welding; — 224 – Wire seam welding; — 225 – foil butt-seam welding; — 226 – seam welding with strip; — 23 – projection welding; — 231 – indirect projection welding; — 232 – direct projection welding.
