阻焊.可焊性.第1部分:金属材料的电阻点焊、缝焊和凸焊的可焊性评定

[中文适用范围]： 本文件规定了评估无涂层和涂层金属的电阻点焊、缝焊和凸焊的一般可焊性的程序。 本文件中描述的测试的目的是 a) 比较不同金属的冶金可焊性，b) 评估不同部件设计的可焊性，例如尺寸配置、层叠、投影几何形状等，c) 研究效果焊接参数（例如焊接电流、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））的变化对可焊性的影响，和/或 d) 比较电阻焊设备的性能。 所使用的测试程序的精确细节取决于将相对于所获得的焊接结果评估项目a)至d)的哪一方面。 [外文原描述]： This document specifies procedures for assessing the generic weldability for resistance spot, seam and projection welding of uncoated and coated metals. The purpose of the tests described in this document are to a) compare the metallurgical weldability of different metals, b) assess the weldability of differing component designs, e.g. dimensional configuration, stack-up, projection geometry, etc., c) investigate the effect of changes in welding parameters such as welding current, weld time, electrode force or complex welding schedules including pulse welding, current stepping etc. on weldability, and/or d) compare the performance of resistance welding equipment. Precise details of the test procedure to be used depend on which aspect of items a) to d) will be evaluated relative to the welding result obtained.
