Application of finite element method, the mechanism of metal flow and weld line movement of U-shape parts with transverse welding line and U-shape parts with longitudinal welding line was investigated, respectively. Research results show that: for U-shape parts with transverse welding line, amount of material pulled in is the main factor that affects the weld line movement, control the blank holder force of thin side is an effective method of control weld line movement. For U-shape parts with longitudinal welding line, amount of material stretch is the main factor that affects the weld line movement, application of segmental blank holder can achieve the purpose of control weld line movement, and pressurization of larger blank holder force on the thick side than thin side.
