Abstract: The two-piece lifting gate is easy to form electrophoretic flow marks at the welding joints of two sheet metal pieces, which affects the appearance quality of the product and increases the cost of manual grinding in the following process. This paper analyzes the mechanism and reasons of electrophoresis flow marks of two-piece lifting gate, and proposes the design requirements of the two-piece lifting gate through the summary analysis of the problem of electrophoretic flow marks, which provides a reference scheme to solve the problem of electrophoretic flow marks.
