<p>ISO 18278-1:2004 recommends procedures for determining the generic weldability for resistance spot, seam and projection welding of metallic materials.</p>
<p>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.</p>
<p>The weldability of metallic materials in resistance welding is defined in terms of:</p>
<ul><li>the ability to make the weld in the first place;</li><li>the ability to continue making welds;</li><li>the ability of the weld to withstand the imposed service stresses.</li></ul>
<p>The procedures recommended in ISO 18278-1:2004 can be used to:</p>
<ul><li>compare the weldability of different metallic materials;</li><li>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;</li><li>determine the weldability of a material when any welding configuration is changed e.g. electrode material and/or shape, water cooling requirements etc.;</li><li>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.</li></ul>
