摘要：
The document discusses the possibility of contact area estimation during resistance spot welding employing post-weld 3D measurement of electrode indentation. Experimental welding of a common type of mild zinc-coated steel was conducted using two different electrode tip types varying welding time, RMS current and number of successive welds. The other parameters (clamping force, voltage, pre- and post-weld time, weld-piece thickness) were constant. The results show that this approach gives valuable information on the conditions under which the weld-spot was formed.
