ISO 14327:2004 specifies procedures for determining the weldability lobe for producing quality welds. The tests are used in particular to determine the weldability lobe for coated/uncoated steels, stainless steels and aluminium and its alloys but may also be used for other metallic materials.The aim of this procedure is to allow determination of the range of welding parameters which give rise to an acceptable weld quality as defined within precise limits. The procedure can be used to determine:The influence of electrode material, electrode shape and dimensions on the available welding range for a particular material and welding machine.The influence of material type and thickness on the available welding range when using a particular combination of welding electrodes and welding machine.The influence of welding machine type, or electrode cooling on the available welding range for a particular material using a particular electrode shape.The available welding range in a production situation.

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.
