about spot welding

greenspun.com : LUSENET : Resistance Welding : One Thread

dear sir/madam I visited your web at internet. It was wonderful. I study metallurgy engineering in Ms in Iran. I am doing a research work in one of the automobile companeis in Iran about spot welding.I have investigated a lot but i didnt get any good result.the problem is that: the outer and inner paneles of automobile which are made of steel are subjected to spot weld after heming, but these spot welds dont create any nuggets. my question is that how we can create a good spot welding with changing of welding parameters.( the thickness of each sheet in under 2mm). i look forward to hearing from you. your sincerely sedigheh bagheri
