The finished U-stiffener need to be assembled into bridge-face assembly. For the purpose of automatic large volume production, the U-stiffener assembly machine, U-stiffener multi-head welding machine can be used. Considering the effect of welding distortion, there are two kinds of technology for selection: one is to straightening woth flame uniformly after assembly, Another is to take use of anti-distortion fixture post welding, which can achieve straightness of the work-piece.
