CO_2气体保护焊丝表面质量分析及润滑材料研究

Surface quality analysis of CO_2 gas shielded welding wires and study of lubricating materials

本文应用电子扫描试验技术及能谱分析方法，从不同工艺条件下生产的镀钢焊丝的表面分析入手，揭示了焊丝表面的形貌，研究和分析了产生缺陷的原因。结果表明，拉拔过程中的固体润滑剂的性能直接影响着表面质量，在此基础上研制出较为理想的长链双分子层结构纽带型润滑剂，提高了润滑的多种性能，本文还对润滑剂尼厚度进行了理论计算，并对各物理因素对厚度的影响进行了分析讨论，提出了一种润滑膜厚度的试验分析方法。

In this papcr the clcctronic scanning tcchnique and cncrgy spectrum analysishavc becn employcd to analyzc the surface of the copper platcd welding wire pro-duccd undcr differcnt technological conditions with a viwe to studing the morphologyof wire and the causc of defect occurring. The ressults show that the propcrties of thesolid lubricant used during drawing excrts a dircct influcnce on the wire surface quali-ty. On this basis、a more satisfactory twistincss bele lubricant with bilavcr is dcvcl-opcd.This lubricant can improve many of the propertics of lubricating film,This pa-per has also made a thcorctical calculation of the thickness of lubricating film as wellas an analysis and discussion on the physical factors affecting the thickncss.Thc au-thors suggcst a method to test and analyzc the thickncss of lubricating film.
