标准范围

ISO 18278-1:20 04推荐了确定金属材料电阻点焊、缝焊和凸焊的一般可焊性的程序。本程序适用于评估单个厚度小于或等于5mm的无涂层/涂层钢、不锈钢和非铁合金（如铝、钛、镁和镍）及其合金）的可焊性。金属材料在电阻焊中的可焊性定义为:首先进行焊接的能力；继续进行焊接的能力；焊缝承受施加的工作应力的能力。ISO 18278-1:20 04中推荐的程序可用于:比较不同金属材料的焊接性；比较特定焊接设备的焊接响应，并允许在不同设备之间进行比较，并确定不同焊接设备的静态/动态特性的影响；当任何焊接配置改变时，例如电极材料和/或形状、水冷要求等，确定材料的可焊性；研究焊接参数如焊接电流、焊接时间、电极力或复杂焊接方案（包括脉冲焊接、电流步进等）的影响。对焊接性。

ISO 18278-1:2004 recommends procedures for determining the generic weldability for resistance spot, seam and projection welding of metallic materials.This procedure is applicable for the assessment of the weldability of uncoated/coated steels, stainless steels and non-ferrous alloys such as aluminium, titanium, magnesium and nickel and their alloys of single thickness lower than or equal to 5 mm.The weldability of metallic materials in resistance welding is defined in terms of:

• the ability to make the weld in the first place;
• the ability to continue making welds;
• the ability of the weld to withstand the imposed service stresses.

• compare the weldability of different metallic materials;
• compare the welding response of particular welding equipment and allow comparisons between different equipment and determine the influence of the static/dynamic properties of different welding equipment;
• determine the weldability of a material when any welding configuration is changed e.g. electrode material and/or shape, water cooling requirements etc.;
• investigate the effect of welding parameters such as welding current, weld time, electrode force or complex welding schedules including pulse welding, current stepping etc. on weldability.
