白车身试制点焊工艺及焊钳选型研究

Research on Spot Welding Technology and Electrode Holder Selection for Body in White of Trial Production

电阻点焊被广泛应用于白车身焊接试制中,其焊接质量直接影响白车身的尺寸精度,从而对汽车的整个试制及研发过程产生影响。因此文章基于白车身试制,对电阻点焊工艺进行了简要介绍,分析了手动点焊钳的基本结构,并且结合实例对手动点焊钳的选型进行详细阐述。

Resistance spot welding is widely used in BIW welding trial production.Its welding quality directly affects the dimensional accuracy.It has an impact on the whole trial production and research and development process of automobiles.Therefore,based on BIW trial production,the resistance spot welding process is briefly introduced.Then the basic structure of the manual electrode holder is analyzed,and the selection of the electrode holder is described in detail with examples.
