摘　　要：电泳流痕问题是车身涂装过程中的一大顽疾,严重的流痕不但会影响外观还会降低车身品质。造成电泳流痕的因素有多种,包括车身钣金结构(间隙)、电泳液特性、电泳后清洗工艺、UF液含漆量和烘烤温度等。以车身B柱过线孔部位为例,对钣金间隙对电泳流痕的影响进行了重点研究。Electrophoretic flow mark in car-body coating process is one of the major ills that will not only affect the appearance but also reduce the body quality. There are many factors that cause electrophoretic flow mark, including car-body structure （gap）, electrophoretic liquid characteristics, electrophoresis after cleaning process, UF liquid containing amount of paint and baking temperature. In this paper, taking wire via body B column for example, in view of the key research on the relationship about the sheet metal gap and electrophoretic flow marks.
