标准范围

本文件规定了制造铝板组件、挤压件（加工硬化和时效硬化合金）和/或铸造材料（包括两种或三种金属厚度）时的电阻点焊要求，其中待焊接部件的最大单板厚度在0.6 mm至6 mm范围内。本文件适用于厚度比小于或等于3:1的不同厚度板材或板材的焊接。适用于总厚度小于或等于9 mm的三种厚度的焊接。使用以下类型的机器进行焊接属于本文件的范围:-底座焊接机；-枪焊工；-由机器人或自动送料设备送料的自动焊接设备；-多焊工；-机器人焊工。有关适当焊接设备的信息见附录A，点焊条件见附录B。后者仅供参考，可能需要根据制造的使用条件、焊接设备的类型、二次回路的特性、电极材料和几何形状进行修改。涂层材料（例如镀锌或阳极氧化材料）的焊接不在本文件范围内。

This document specifies requirements for resistance spot welding in the fabrication of assemblies of aluminium sheet, extrusions (both work- and age-hardening alloys) and/or cast material comprising two or three thicknesses of metal, where the maximum single (sheet) thickness of components to be welded is within the range 0,6 mm to 6 mm.This document is applicable to the welding of sheets or plates of dissimilar thickness where the thickness ratio is less than or equal to 3:1. It applies to the welding of three thicknesses where the total thickness is less than or equal to 9 mm.Welding with the following types of machines is within the scope of this document:— pedestal welding machines;— gun welders;— automatic welding equipment where the components are fed by robots or automatic feeding equipment;— multi-welders;— robotic welders.Information on appropriate welding equipment is given in Annex A and on spot welding conditions in Annex B. The latter are for guidance only and can require modification depending on service conditions of the fabrication, type of welding equipment, characteristics of the secondary circuit, electrode material and geometry.The welding of coated material, e.g. zinc-coated or anodized material, is outside the scope of this document.
