| Abstract: | The objective of this work was to measure the out - of - plane distortion and introduce a distortion control measure during welding fabrication. In this paper, a measurement method was defined, the primary distortion modes were identified for the side - wall of carriage, the finite element analysis for predicting distortion in carriage structure was developed. Finally, the method for reducing distortion ais introduced. |
