标准范围

本文件规定了可用于点焊、缝焊和凸焊工艺焊接工艺规范评定的试验。注:本程序适用于浮雕凸焊。它们也可用于实体投影，例如螺母焊接、螺柱焊接。交叉焊丝焊接。本文件规定了本文件涵盖的所有实际焊接操作的试验条件和合格焊接工艺的有效范围。它包括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–搭接缝焊接；-？222–压缝焊接；-？223–准备搭接焊缝焊接；-？224–线缝焊；-225–箔式对接焊缝；-？226–带条缝焊；-？23–凸焊；-？231–间接凸焊；-？232–直接投影焊接。

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.
